Follow-up on Comodo and XpAntivirus2008
The other day I reported that Comodo had revoked all certificates issued to WinFixer/SetupAHost ... as you can see below this is the report IE displays when the error occurs ... kudos to Comodo! ... Sandi has another example here

Now to follow-up on XpAntivirus2008 that I wrote about ... looks like they have been busy registering more sites, but using the exact same fake scanner results ...

Bharath's Security Blog has more details on the additional sites involved ...
