Free antivirus srtuck on 0% screen

Quick scan always sticks on a screen saying scanning for malware 0% (and yet it also indicates that it is OK having been checked for viruses and malware). Can’t even stop the scan as it doesn’t respond at all.

I have attached a screen shot of the screen.

Have you tried repair and reboot? https://support.avast.com/en-eu/article/Repair-Antivirus

Hi Pondus and thank you, but I have tried that and it makes no difference (other than now the file it has stopped on is C:\Windows\ehome\mcupdate.exe

Do you have any McAfee programs installed?

No, that folder seems to be Media Centre

maybe a uninstall reboot and reinstall help? If not i dont know

Yeah, was hoping to avoid that, but suspect you are right.

Thanks.
