Yeah, but I’ve read that MBAM 1.5 Free doesn’t provide real-time protection.
And no conflicts are found with Ad-Aware… uninstallation of Ad-Aware still results in the same problem detailed above in Avast. No other problems noted between Avast and Ad-Aware.

How about this:

It’s got real-time protection, faster scanning than MBAM, better detection rates on both Full and Smart scans than either Ad-Aware or MBAM, and is compatible with AV programs.
