i post an attachment i cant get the whole scan on it.
dear whom ever is in charge or has a clue why is avast still doing this ,it still shows up that i have a root-kit virus but i dont ,i guess i will get a different anti-virus i cant even run a scan on my machine or it will start saying i have a rootkit virus …
There is a well known bug with rootkit detection.
Until it’s solved, as a workaround, disable rootkit scanning in the Trobleshooting tab of program settings.
