Please report any scam domains to any antivirus company that will accept a report from regular people. Lots of them make web filters in browser extensions and/or their security products and appreciate information like that being submitted to them.
Addendum! If you see a scam call center impersonating one or more antivirus companies. Report the scam to antivirus companies too.
For some reason the link to comodo’s form shows up as an ad or something, sorry about that.
