OK, I ran both scanners once, then reinstalled Avast and turned on MS firewall. I didn't see your post about scanning twice, so after installing Avast I ran them both again.
Sorry, but how do I use regedit to scan for leftovers? (after installing Avast) I go to Run, type regedit, and in there I do see a KasperskyLab entry, and under it a 'protected' folder. Do I highlight that and hit Delete? I don't see any Comodo in there.
Under Microsoft, I don't see anything named MSE.
also how do I create a backup of registry?
really appreciate the handholding during all of this :-)
