I, alongside many well researched and security minded folk here, use Bufferzone pro.
If I had to choose between av and BZ, bz would win. However, I shouldn't need to make that choice. But, I think there may be compatibility issues between the two, since much of the install is in docs and settings, which I delete monthly anyway volutarily or other wise. Also, there may be background upgrading and storage into this area, meaning BZ will put into this virtual, disposable area, and confusing area, rather than into the immunet directory.
don't care what they are teaching you. Never design a program that puts settings and install into a disposable area. Backing up into this area is okay, but don't rely on the registry or docs and setting to be present on next boot! ---experienced PC user.
