where can i find the uninstall utility… ???

Here is the direct link

The link to the page on the Uninstall Utility was posted by Pondus.

Having found the uninstall utility (aswclear.exe), on the page that you download it from it states that you should run it from safe mode. avast doesn’t run in safe mode so there is no self-defence module running either to stop the uninstall utility from doing its job.
