    Just like Saktinath said above, I installed CCleaner update and just as I was clicking “Continue” I noticed I forgot to uncheck “Install Avast too.”

    I had no ill-feeling against Avast before attempting to uninstall it, but NOW I HATE AVAST and recognize Avast as malware.

    Avast was installed surreptiously with CCleaner update. It has no “Uninstall” option as it is not detected in Windows “Apps & Features” & other Uninstall utilities like “Revo Uninstaller”/”CCleaner”. The coders of Avast have played a cruel joke with ordinary PC users. To remove it completely requires advanced knowledge of editing Registry entries. The other option is to wipe the hard disk. To sum up Avast is the worst Malware I’ve ever encountered.
