Avast leaves a lot of garbage behind the computer and in the registry. Especially troublesome registry entries can, for example, be an obstacle to installing another antivirus Avast after. In such cases, you can use a particular utility, Avast! Clear.
Sometimes, it's impossible to uninstall Avast using the ADD/REMOVE PROGRAMS in the control panel. In this case, you can use this uninstallation utility, avastclear.
This is a particular tool that has been designed to be used to get rid of and, in the case of Avast! Antivirus Free and Professional, or Avast! Internet Security. Installing the app is unnecessary as it is a standalone tool – fire it up, and it will quickly remove any files or registry entries left behind.
You should first run through the regular uninstaller for your avast! Tool, or you will find that this utility has no effect. If you have other anti-malware software installed, Avast Clear (Uninstall Utility) may be flagged as suspicious, but it is perfectly safe.
Download avastclear.exe on your desktop
Start Windows in Safe Mode
Open (execute) the uninstall utility
If you installed Avast in a different folder than the default, browse for it. (Note: Be careful! It will delete the content of any folder you choose!)
