When I finished downloaded the "avastclear" then I boot into safe mode, but still, an error window appeared saying : "The avast! self protection module is enabled. For this reason, the operation cannot be completed" ---- When I open avast antivurus to disable that module, the avast suddenly closed, when i open it again, it suddenly closed again... I was able to uncheck the "enable self-protect module" but when avast! closes, that module is enabled again. PLEASE, HELP ME! What should I do? I need to uninstall Avast! as soon as possible. Please reply IMMEDIATELY!!
Thank You Very Much.
