Getting bad URL warnings when running firefox

I get Avast warnings when running firefox.

I’ve run Malwarebytes Anti-malware + Farbar + aswMBR. (Scans only, waiting for replies before running removals/fixes).

I also get a warning from SysWOW64/rundll32.exe

Logs attached.

there seems to be a forum issue where posts sometimes disappear, it is reported and i guess they are looking for the bug
