Computer Viruses in Windows virtual machines

254 users found this article helpful



Parallels Desktop for Mac runs guest OS in special virtualized environment that emulates entire computer. This virtualized computer is as vulnerable to viruses as an usual PC running Windows. We highly recommend you to have antivirus (AV) software installed in the guest OS.

You may install any preferable antivirus software compatible with the version of Windows OS you are running in virtual machine.

Don't run multiple antivirus software in one OS: system performance will be significantly decreased due to AV software conflict.

NOTE: Please be aware that although computer viruses and similar malicious software cannot affect Mac OS X itself, it may corrupt Shared Folders content which is accessible from Windows side, so we recommend that you avoid storing any important data there (or at least create backups).
