Which is the same as what Pondus posted, but seems that the OP didn't "catch" it.
I got that allright, but it'll just remove Avast from my pc.. Or does it as well remove any other leftover?
I think you are mixing things/posts here. One thing is removing avast's leftovers following the instructions from
http://www.avast.com/uninstall-utility.
What
Pondus also posted, in
REPLY#1, was that you probably have/had some other pre-installed antivirus. You should uninstall that antivirus, and whether you actually got to use it ever, or disabled it immediately, you should anyway run the respective removal utility for that other antivirus, the one pre-installed in your system (like, for example, Norton Symantec, or any other).
For that other antivirus, that most probably left you with remnants, you should review if you already uninstalled it from "Add/Remove Programs", then reboot, and then read the appropriate instruction in the respective "info" link (according to that other antivirus), located at
http://singularlabs.com/uninstallers/security-software/. With the respective info, run the respective removal utility for that other pre-installed antivirus.
Then, when your system is really free from conflicts, install avast anew (clean latest stable install, with no previous registry keys, no "avast" folders, no "alwil" folders),
reboot, report back, and if there is still another problem, then we can give you more instructions.
Let's hope we were clear enough this time.
