I've been running Avast (Free) and Microsoft Security Essentials (MSSE) together for several months. I recently built a new box and included Windows 7 Professional. I installed new apps for Avast and MSSE (did NOT install Windows Defender, but disabled it when it appeared), and everything ran fine until the last Avast update. Since then, I consistently receive threat warnings, listing 33 instances of msmpeng.exe, each defining a different trojan, worm, virus, info, etc.
I've been corresponding with Avast tech support, and tried their suggestions, but I still get the same threat warnings. When I run MalwareBytes and SuperAntiSpyware, neither one throws any flags. I don't want to uninstall Avast or MSSE, and thought about disabling all features except the mail scan in Avast. Anybody have problems like this?
