Does Microsoft Security Essentials work with other antivirus software?

Yes, you should uninstall McAfee Suite before installing Microsoft Security Essentials.

Microsoft Security Essentials is free software that helps protect against viruses, spyware, worms, and other malware or unwanted software. If you use Microsoft Security Essentials, you don’t need to install any other antivirus or antispyware software.

In fact, if you run more than one antivirus or antispyware program at once, it might affect your computer’s performance. For more information, see Uninstalling existing antivirus or antispyware programs before installing Microsoft Security Essentials.

Bottom line? You should choose one antivirus program. Obviously, we recommend Microsoft Security Essentials, but we’re not alone: others recommend it too.
