If MacKeeper Antivirus detects any malicious items, you’ll see their full list on your screen.

What to do with any items Antivirus finds

You can either delete the infected items or move them to quarantine. For security reasons, we recommend deleting all infected items.


1. Check if infected files are important for the system


If you suspect that the file marked as infected is important for an application or the macOS system, you can put it into quarantine. To check if the infected items are important for the system, you can check their location by pressing ^(Control) and clicking the file then selecting Reveal in Finder.


2. Decide if you want to delete or quarantine the files


If the file is located in any user folder (Downloads, Documents, Pictures, Music, Desktop, Trash etc.), feel free to delete it.


If the file is located in any other folders, you may quarantine it to avoid the app or system misbehavior. Quarantined files cannot damage the system as they are blocked.


3. Select the infected files to delete or quarantine


By default, MacKeeper selects all detected items. If you want to manually review each one and go through item-by-item, deselect the Check All checkbox, and select the items you want to delete or quarantine.


4. To delete infected items, click the white Delete button at the bottom of the list and confirm it in the confirmation window 


Next, you’ll see a “Deleting Completed” message. Note that if you didn’t delete all infected items, you’ll see the Proceed button. Click it to continue with the remaining items.


5. To quarantine infected items, click the blue Quarantine button at the bottom of the list


Once you’re done with deleting or quarantining all found items, you can click the Restart button. This starts a new Mac virus scan to make sure your Mac is safe. 

How to access the Antivirus Quarantine

The files you put into quarantine don’t disappear. Here’s how to access them:

  1. Open Antivirus and click the Review button
  2. Click the white Restore button to take the infected file out of quarantine — note, it might affect your Mac’s security
  3. Click the blue Delete button to completely remove the selected file from your Mac
