When you're happy with your configuration, you can use the test file provided by eicar to verify that the two computers play nicely with each other in a threatening situation. I'd say, most important is for access to the threat to be denied in both computers, then you (the user) can use your preferred computer to deal with the threat. To avoid contention: configure at least one antivirus software title to not automatically move, remove or disinfect files that present a threat. On the contrary, it will only improve the safety of your PC.

Thank you for posting in Microsoft community. You dont have to worry about running into security vulnerabilities while using this software. Why can I not download the new Free Essential Version, Im already using the old New Free Classic Version. Dual protection of this type is OK, if there is no contention. Microsoft Security Essentials is a high-quality antivirus product that was developed to keep your computer secure. Rule of thumb: the antivirus software on your host computer (in this case, Sophos Anti-Virus Home Edition) will not protect the guest computer (in this case, Windows XP Pro) - and vice versa, Microsoft Security Essentials on Windows will not protect the Mac.īeing without antivirus software on either computer would be risky.ĭepending on the level of host/guest integration provided by the VM software (in this case, Parallels Desktop for Mac), files in certain areas may be protected by both computers.
