I am a long-time avast user, forced to switch to another AV because of repeating problems with System Restore on my main PC (windows 7/64). At the moment I’m trying MSE, since it seemed to me most likely it shouldn’t have problems with SR. And it works.

While waiting for the problem to be fixed, I’m still using free avast on an old netbook (with Syst. Restore disabled) and testing last beta version on a XP virtual machine (no problems with SR there).

That’s all.
