In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, email messages are automatically protected against malware by EOP. EOP uses anti-malware policies for malware protection settings. For more information, see Anti-malware protection.
Admins can view, edit, and configure (but not delete) the default anti-malware policy to meet the needs of their organizations. For greater granularity, you can also create custom anti-malware policies that apply to specific users, groups, or domains in your organization. Custom policies always take precedence over the default policy, but you can change the priority (running order) of your custom policies.
You can configure anti-malware policies in the Security & Compliance Center or in PowerShell (Exchange Online PowerShell for Microsoft 365 organizations with mailboxes in Exchange Online; standalone EOP PowerShell for organizations without Exchange Online mailboxes).

To add more conditions, click Add condition and select from the remaining options.- Except if: To add exceptions for the rule, click Add exception, click on the Select one drop-down, and configure the exceptions. The settings and behavior are exactly like the conditions.
- When you're finished, click Save.
Use the Security & Compliance Center to view anti-malware policies
- In the Security & Compliance Center, go to Threat management > Policy > Anti-Malware.
- When you select a policy, information about the policy is displayed in the details pane. To see more information about the policy, click Edit .
- The Enabled property value, the Priority property value, and the settings on the Applied to tab are in the malware filter rule.
- The settings on the General and Settings tabs are in the malware filter policy.
Use the Security & Compliance Center to modify anti-malware policies
- In the Security & Compliance Center, go to Threat management > Policy > Anti-Malware.
- Select the policy, and then click Edit . For information about the settings, see the Use the Security & Compliance Center to create anti-malware policies section in this topic.Notes:
- Instead of everything on one page, the settings are divided among the General, Settings, and Applied to tabs. The Applied to tab isn't available in the default policy named Default (which is automatically applied to everyone).
- You can't rename the default policy.
Use the Security & Compliance Center to enable or disable anti-malware policies
- In the Security & Compliance Center, go to Threat management > Policy > Anti-Malware.
- Select the policy from the list, and then configure one of the following settings:
- Disable the policy: Clear the check box in the Enabled column. By default, anti-malware policies are enabled when you create them in the Security & Compliance Center.
- Enable the policy: Select the check box in the Enabled column.
Use the Security & Compliance Center to set the priority of custom anti-malware policies
By default, anti-malware policies are given a priority that's based on the order they were created in (newer polices are lower priority than older policies). A lower priority number indicates a higher priority for the policy, and policies are processed in priority order (higher priority policies are processed before lower priority policies). No two policies can have the same priority, and policy processing stops after the first policy is applied.
Notes:
- In the Security & Compliance Center, you can only change the priority of the anti-malware policy after you create it. In PowerShell, you can override the default priority when you create the malware filter rule (which can affect the priority of existing rules).
- In the Security & Compliance Center, anti-malware policies are processed in the order that they're displayed (the first policy has the Priority value 0). The default anti-malware policy named Default has the priority value Lowest, and you can't change it.
To change the priority of a policy, move the policy up or down in the list (you can't directly modify the Priority number in the Security & Compliance Center).
- In the Security & Compliance Center, go to Threat management > Policy > Anti-Malware.
- Select a policy, and then click Move up or Move down to move the rule up or down in the list.
Use the Security & Compliance Center to remove anti-malware policies
When you use the Security & Compliance Center to remove an anti-malware policy, the malware filter rule and the corresponding malware filter policy are both deleted.
- In the Security & Compliance Center, go to Threat management > Policy > Anti-Malware.
- Select the anti-malware policy you want to remove from the list, and then click Delete .
Use Exchange Online PowerShell or standalone EOP PowerShell to configure anti-malware policies
Use PowerShell to create anti-malware policies
Creating an anti-malware policy in PowerShell is a two-step process:
- Create the malware filter policy.
- Create the malware filter rule that specifies the malware filter policy that the rule applies to.
Notes:
- You can create a new malware filter rule and assign an existing, unassociated malware filter policy to it. A malware filter rule can't be associated with more than one malware filter policy.
- There are two settings that you can configure on new anti-malware policies in PowerShell that aren't available in the Security & Compliance Center until after you create the policy:
- Create the new policy as disabled (Enabled
$false
on the New-MalwareFilterRule cmdlet). - Set the priority of the policy during creation (Priority<Number>) on the New-MalwareFilterRule cmdlet).
- A new malware filter policy that you create in PowerShell isn't visible in the Security & Compliance Center until you assign the policy to a malware filter rule.
Step 1: Use PowerShell to create a malware filter policy
Note: In EOP, the Action parameter values
DeleteMessage
, DeleteAttachmentAndUseDefaultAlert
, and DeleteAttachmentAndUseCustomAlert
don't delete messages. Instead, the messages are quarantined. For more information about retrieving quarantined messages, see Manage quarantined messages and files as an admin in EOP.To create a malware filter policy, use this syntax:
This example creates a new malware filter policy named Contoso Malware Filter Policy with these settings:
- Quarantine messages that contain malware without notifying the recipients (we aren't using the Action parameter, and the default value is
DeleteMessage
). - Don't notify the message sender when malware is detected in the message (we aren't using the EnableExternalSenderNotifications or EnableInternalSenderNotifications parameters, and the default value for both is
$false
). - Notify the administrator [email protected] when malware is detected in a message from an internal sender.
For detailed syntax and parameter information, see New-MalwareFilterPolicy.
Step 2: Use PowerShell to create a malware filter rule
To create a malware filter rule, use this syntax:
This example creates a new malware filter rule named Contoso Recipients with these settings:
- The malware filter policy named Contoso Malware Filter Policy is associated with the rule.
- The rule applies to recipients in the contoso.com domain.
For detailed syntax and parameter information, see New-MalwareFilterRule.
Use PowerShell to view malware filter policies
To return a summary list of all malware filter policies, run this command:
To return detailed information about a specific malware filter policy, use the this syntax:
This example returns all the property values for the malware filter policy named Executives.
This example returns only the specified properties for the same policy.
For detailed syntax and parameter information, see Get-MalwareFilterPolicy.
Use PowerShell to view malware filter rules
To return a summary list of all malware filter rules, run this command:
To filter the list by enabled or disabled rules, run the following commands:
To return detailed information about a specific malware filter rule, use this syntax:
This example returns all the property values for the malware filter rule named Executives.
This example returns only the specified properties for the same rule.
For detailed syntax and parameter information, see Get-MalwareFilterRule.
Use PowerShell to modify malware filter policies
Other than the following items, the same settings are available when you modify a malware filter policy in PowerShell as when you create the policy as described in the Step 1: Use PowerShell to create a malware filter policy section earlier in this topic.
- The MakeDefault switch that turns the specified policy into the default policy (applied to everyone, unmodifiable Lowest priority, and you can't delete it) is only available when you modify a malware filter policy in PowerShell.
- You can't rename a malware filter policy (the Set-MalwareFilterPolicy cmdlet has no Name parameter). When you rename an anti-malware policy in the Security & Compliance Center, you're only renaming the malware filter rule.
To modify a malware filter policy, use this syntax:
For detailed syntax and parameter information, see Set-MalwareFilterPolicy.
Use PowerShell to modify malware filter rules
The only setting that isn't available when you modify a malware filter rule in PowerShell is the Enabled parameter that allows you to create a disabled rule. To enable or disable existing malware filter rules, see the next section.
Otherwise, no additional settings are available when you modify a malware filter rule in PowerShell. The same settings are available when you create a rule as described in the Step 2: Use PowerShell to create a malware filter rule section earlier in this topic.
Pp file viewer. To modify a malware filter rule, use this syntax:
For detailed syntax and parameter information, see Set-MalwareFilterRule.
Use PowerShell to enable or disable malware filter rules
Enabling or disabling a malware filter rule in PowerShell enables or disables the whole anti-malware policy (the malware filter rule and the assigned malware filter policy). You can't enable or disable the default anti-malware policy (it's always always applied to all recipients).
To enable or disable a malware filter rule in PowerShell, use this syntax:
This example disables the malware filter rule named Marketing Department.
This example enables same rule.
For detailed syntax and parameter information, see Enable-MalwareFilterRule and Disable-MalwareFilterRule.
Use PowerShell to set the priority of malware filter rules
The highest priority value you can set on a rule is 0. The lowest value you can set depends on the number of rules. For example, if you have five rules, you can use the priority values 0 through 4. Changing the priority of an existing rule can have a cascading effect on other rules. For example, if you have five custom rules (priorities 0 through 4), and you change the priority of a rule to 2, the existing rule with priority 2 is changed to priority 3, and the rule with priority 3 is changed to priority 4.
To set the priority of a malware filter rule in PowerShell, use the following syntax:
This example sets the priority of the rule named Marketing Department to 2. All existing rules that have a priority less than or equal to 2 are decreased by 1 (their priority numbers are increased by 1).
Notes:
- To set the priority of a new rule when you create it, use the Priority parameter on the New-MalwareFilterRule cmdlet instead.
- The default malware filter policy doesn't have a corresponding malware filter rule, and it always has the unmodifiable priority value Lowest.
Use PowerShell to remove malware filter policies
When you use PowerShell to remove a malware filter policy, the corresponding malware filter rule isn't removed.
To remove a malware filter policy in PowerShell, use this syntax:
This example removes the malware filter policy named Marketing Department.
For detailed syntax and parameter information, see Remove-MalwareFilterPolicy.
Use PowerShell to remove malware filter rules
When you use PowerShell to remove a malware filter rule, the corresponding malware filter policy isn't removed.
To remove a malware filter rule in PowerShell, use this syntax:

This example removes the malware filter rule named Marketing Department.
For detailed syntax and parameter information, see Remove-MalwareFilterRule.
How do you know these procedures worked?
Use the EICAR.TXT file to verify your anti-malware policy settings
Important
The EICAR.TXT file is not a virus. The European Institute for Computer Antivirus Research (EICAR) developed this file to safely test anti-virus installations and settings.
- Open Notepad and paste the following text into an empty file:Be sure that these are the only text characters in the file. The file size should be 68 bytes.
- Save the file as EICAR.TXTIn your desktop anti-virus program, be sure to exclude the EICAR.TXT from scanning (otherwise, the file will be quarantined).
- Send an email message that contains the EICAR.TXT file as an attachment, using an email client that won't automatically block the file. Use your anti-malware policy settings to determine the following scenarios to test:
- Email from an internal mailbox to an internal recipient.
- Email from an internal mailbox to an external recipient.
- Email from an external mailbox to an internal recipient.
- Verify that the message was quarantined, and verify the recipient and sender notification results based on your anti-malware policy settings. For example:
- Recipients aren't notified, or recipients receive the original message with the EICAR.TXT attachment replaced by Malware Alert Text.txt that contains the default or customized text.
- Internal or external senders are notified with the default or customized notification messages.
- The admin email address that you specified is notified for internal or external message senders, with the default or customized notification messages.
- Delete the EICAR.TXT file after your testing is complete (so other users aren't unnecessarily alarmed by it).
Summary :
Are you bothered by virus attack? Do you want to recover files deleted by virus attack? If you are seeking solution to files deleted by virus attack, you should read this post. This post discusses how to recover files deleted by virus attack with a third-party tool or the Windows built-in tool.
Quick Navigation :
Maybe you have ever heard of computer virus, but never have a chance to experience it. Believe us, encountering virus is a fairly common occurrence. According to statistics, more than half of the computer users have the experience of being attacked by virus and some of them are even frequently bothered by it, failing to get rid of this issue.
Definitely, the most annoying thing during virus attack is claimed to be struggling to recover files deleted by virus attack.
Imagine this: your presentation files, which were planed to show in the company meeting the next day are totally lost from computer when virus is detected, how depressed you will be. These files may be finished after days of or even months of hard work. Besides, the lost files could be the symbol of people’s past good days, which may include an unforgettable memory of deceased friend. That means, the file is unique, it can never be recreated again.
Certainly, users who lose important data and are not willing to accept this fact and will try their best to recover missing files after virus attack at any cost.
How to Recover Files Deleted by Virus Attack
In this part, I will introduce two commonly used way to help you with files recovery after virus attack.
Recover Lost Files after Virus Attack with Third-party Tool
I feel it’s really necessary to introduce an effective and easy way to help you regain your lost files after getting attacked by virus. That is to recover files with MiniTool Power Data Recovery, a piece of powerful third-party tool that has been used and praised by tens of thousands of people.
I’ll show you how to finish the recovery work in two different situations.
Situation 1: the computer works fine after virus attack.
The common issue is that some files, including text files, photos, audio files and videos are missing after your computer has been invaded by virus. And it’s often too late when you have finally detected it. The needed files may get lost without a warning and users got no way to cancel such deletion performed automatically by virus.
In this case, I strongly suggest you to follow this tutorial to recover virus deleted files from PC.
Step 1: download, install and run MiniTool Power Data Recovery as soon as possible to start recovery (please remember not to install this software to the drive which has been attacked by virus and included files waiting to be recovered).
Step 2: the main interface will appear and you need to choose a suitable option from the left-hand panel. You should figure out which is the most suitable one for your case.
- “This PC” should be selected if you need to recover data from existing partitions.
- “Removable Disk Drive” should be chosen to get back files from a removable disk.
- “Hard Disk Drive” is suitable for data recovery from a hard disk (internal and external).
- “CD/DVD Drive” can be used to retrieve files from damaged CD/DVD.
FYI: WD External Hard Drive Data Recovery Is Easy Enough.
Step 3: after that, please select the disk or partition to scan (by clicking on the “Scan” button) in order to find lost but needed files.
Step 4: when the scan processes, there will be more and more files found by the software and shown to you. At this time, you need to do two things:
- One is to look through the files to find and select needed ones.
- The other is to press the “Save” button in the lower right corner to set a new storage location for those selected files.
After all those steps are finished, you will see a prompt in software, indicating that the recovered work has been done and users are allowed to close the software right away.
Please read this if you are curious about how to recover files deleted permanently on Windows:

Learn the steps to recover permanently deleted files in Windows 10/8/7/XP/Vista after 'shift-delete' or 'empty recycle bin'.
Situation 2: the computer refuses to boot after virus attack.
A more serious problem is that the operating system becomes unbootable after the virus attack. This may happen because virus has damaged the OS, deleted essential boot files or changed the boot settings.
No matter what the reason is, the result would be – you are no longer allowed to enter your own computer by booting from the operating system you often use, so you totally lose access to your files saved on that hard drive, no matter it’s for work, for study or for entertainment, all gone.
If you run into operating system not found or other problems that result in a non-bootable computer, you can’t use the previous method to recover files. But the exciting news is that there’s a bootable edition of MiniTool Power Data Recovery, which can help you access the internal hard drive without booting operating system.
How to do the recovery:
- Firstly, you need to build a bootable CD/DVD/USB disk successfully on another computer.
- Then, you should disconnect the boot disk from that computer and connect it to the target computer which needs recovery.
- After that, you should restart the computer to enter BIOS and set it to boot from this CD/DVD0/USB drive, not the local drive.
- Finally, you should repeat the step 2 ~ step 4 mentioned in the previous method to recover the data you need.
Please read part 2 of Data Recovery From Corrupted Internal Hard Disk – Ultimate Guide to know the following things clearly:
- How to make a boot disk by using the snap-in WinPE Bootable Builder included in an advanced edition of Power Data Recovery. (Click to buy a license to get the snap-in WinPE Bootable Builder)
- How to boot from the disk you’ve made so as to enter the main interface of Power Data Recovery.
Recover Files Deleted by Virus Attack with Microsoft Solutions
In many ways the virus can attack on our computer and other kinds of data storage devices like USB flash drive. And when the virus is activated, it will start to delete files and ruin our OS. If any Windows 7 users discovered this, the first thing they should think of is how to recover deleted files and folders in Windows 7. Retrieving missing files could be a breeze, can you imagine that?
Actually, there’re lots of practical ways for you to find and recover Windows files (take Windows 7 as an example). Now, I’ll talk about two ways that Microsoft Windows provide.
Way 1: restore from a backup.
If you can’t find a file on your computer when you need it or you just performed an accidental deletion to the needed file, you may restore it from a backup (under the premise that they’re enabled Windows backup before).
Email Worm Virus
Here’s how to do to retrieve missing files in Windows 7 by using the Windows backup:
- Click on the Start button from the bottom left corner of computer screen and choose “Control Panel”.
- Choose “System and Security” from above interface and then click “Backup and Restore” from the following page.
- Now, choose “Select another backup to restore files from” or “Recover system setting or your computer” to finish recovery under guidance.
Tip: To use this method for deleted file recovery, users must Open System Restore and Set up backup in advance (before the files are missing).
Way 2: restore previous versions.
You can also try to restore files from previous version. What does this mean? Maybe most of you don’t know the hidden function of Windows – “Restore previous versions”.
To be honest, the previous versions are the copies of files and folders that saved by Windows itself automatically. When you find files in your computer hard disk are lost, you can try to restore the certain drive or folder to its previous versions, in which files are still there.
Here’s how to do the recovery by relying on previous version:
Step 1: get access to the computer hard drive through following two ways.
- One is clicking on Start button from the bottom left corner of computer screen and choosing “Computer”.
- The other is double clicking on “Computer” icon on desktop.
At this time, if users want to recover deleted folder from D drive, they could right click on D drive to see a pop-up menu, in which many options like “Open”, “Open in new window” and “Turn on BitLocker…” are included.
Step 2: find “Restore previous versions” option and choose it to continue.
Step 3: After seeing a list of available previous versions of files and folders, you should choose a favorable restore point to start recovering folder.
But the way, if you want to recover lost files after virus attack from a folder, you should do the following things:
- Enter the certain drive that included target folder before virus attack.
- Afterwards, navigate to the folder that was used to save the needing files.
- And then, right click on it and choose “Restore previous versions” to complete the recovery.
Please note the following things:
- Before restoring a file or folder to its previous version, you are suggested to select a certain previous version, and then click Open to view it in order to make sure that this is the version you actually need.
- But remember, you can’t open or copy previous versions of files and folders that were created by Windows Backup. The only thing you can do is to restore them.
- After you clicked on the “Restore” to restore files from a previous version, the current version will be replaced on computer. What’s more, the replacement can’t be cancel. So please think twice before you really do this.
Kill Virus for Security Concerns
In today’s era, where information and science is well developed, almost everyone is aware of the danger of virus and the importance of killing virus. But do you really know what time is the best time to kill virus?
The Best Time to Kill Virus
Knowing that virus may further ruin the data and operating system after its invasion, most of you think it would be better to kill virus as soon as you can by using powerful antivirus tools.
However, I don’t suggest you to do so. On the contrary, I recommend that you try every means you can to recover files deleted by virus attack firstly before performing any other operations.
Why don’t I suggest you to kill virus before retrieving missing files? The reason is easy-to-understand: antivirus programs may delete some useful files from your computer when removing virus for you. And this may cause secondary damage, deleing more files from computer and making some data gone for good.
Remove File Virus Doc.blower Windows 7
As a result, I suggest you to complete data recovery before they adopt antivirus programs to clean disk, unless the files deleted by virus are of no use.
Here are ransomeware prevention tips for you.
How Virus Enter Your Computer and Ruin Data
With the development of internet, the risk of being attacked by virus boosts. When you click on links sent from untrusted sites or in an anonymous email, you are actually giving way to the hidden computer virus.
There are other actions that are dangerous and may let computer virus invade your OS:
- Use pirated or unknown software/programs/applications.
- Use a new movable device on computer without checking security or killing virus.
- Continue visiting sites on which virus or abnormal operations are detected.
- Download files from network casually, even from unknown sites.
In fact, virus can get into our personal computer through plenty of new ways that you couldn’t think of. That’s why most users would like to roll up their sleeves and start to install a trusted antivirus program when they buy a new computer or reinstall the OS. After the virus entered computer, they may not be activated right away.
Virus Comes with Storage Media
In theory, viruses are attached to storage media like floppy disk and hard disk so as to constitute infection source and the transmission medium is decided by work environment. Virus is put into memory after invasion and the virus creator has already set up the trigger condition, which is diverse. It could be the clock, system date, user identifier or a system communication. When the condition becomes ripe, virus will start replicating itself to infected object and performing various sabotage activities, including:
- Destroying file system
- Changing file name
- Deleting data
Definitely, to recover files deleted by virus attack becomes an urgent thing.
Verdict
All in all, computer virus is more than just a data killer since it actually can cause serious problems to users’ disk and system. Computer virus is for computer what biological virus is for human body. It can put all of us in a tight spot, letting us worry about the ruin of hard work, the loss of unforgettable memory, financial losses, etc.
But you shouldn’t kill virus immediately after getting attacked since this is a dangerous action to your data. You should finish deleted or corrupt files recovery firstly and then do other things you like, such as cleaning the virus.
