No, I have not seen anything that resolves this problem. I am sticking with 5.0.545 until I hear the Avast team acknowledge the problem and fix it.

To Daris: I upgraded from v4.8 by downloading and running the 6.0 installer. When that didn’t work, I uninstalled 6.0 using its deinstaller, then re-ran the installer. I tried uninstall/reinstall several times, and tried various options (e.g., load Avast after other services) and nothing helped.

BTW, why can’t we get older versions of Avast directly from this website? While the files are signed with MS digital signatures, I’d prefer to supplement that level of security by downloading directly from Avast.
