Here’s what our users ask

Check out the answers to the most popular questions asked about MacKeeper Antivirus.

Do I need an antivirus for Mac?

It’s true that Macs are not as prone to malware as other computers. Most Mac infections occur as a result of user behavior. Whereas a Windows system is easily susceptible to a so-called 'drive-by silent infection' that happens through no fault of the user, a Mac infection usually requires some deliberate (and thus avoidable) action. However, a Mac user must be highly computer literate in order to avoid all potential threats.

How can I check my Mac for viruses?

Step 1. Open MacKeeper, select the Antivirus feature, and click the blue Start Scan button in the right panel

Step 2. Wait until the scan is over

Step 3. Decide if you want to delete or quarantine the files.

Step 4. Press Delete or Move to Quarantine

Should I delete or quarantine located items?

When MacKeeper detects a virus, you have two options on how to treat it:

1. Delete This option is the one we recommend. MacKeeper rarely detects false viruses, that’s why we suggest that MacKeeper users delete files detected by MacKeeper's antivirus as they may potentially be harmful.

2. Move to Quarantine With this method, MacKeeper places a potentially harmful file into a special folder. The files from the Quarantine folder cannot be opened, thus become nearly impossible to harm your system. We recommend quarantining viruses if you are sure that MacKeeper has marked your personal file as harmful.

Also, you may try quarantining a harmful file to see if it affects any system processes. If it doesn’t and your system seems to work fine without it, you can safely delete the harmful file.

Safe Mac.
Fast Mac.
