HTML:Script-inf on regsvr32.exe

Viruses and worms
1

Hi all, I’ve been struggling with malware and haven’t been able to get rid of it.

Avast keeps popping-up that it’s blocking infections from random sites at random times. I’ve never been on the sites that Avast is blocking. The infection comes up as HTML:Script-inf and the process is always C:\Windows\SysWOW64\regsvr32.exe.

Here’s a screenshot of the infection pop-up.

I’ve run full scans with Avast, Malwarebytes Anti-Malware, and AdWCleaner. None of them have been successful in finding the infection source.

Any help would be appreciated.
