Hey Goat10,
Seems to be affecting the Jokers across the board.

I had exactly the same experience as Terracotta, Except it screwed my AH login up as well so I missed the 1st HS frame.

For the record my virus was called "backdoor.ftp99" Apparently this is a trojan not a virus and would not do what either you or I have experienced but my system did get back to some kind of normality after removing it so I am assuming the "cleanup" also removed whatever else was lurking. (I had to go back to an old version of AH and install the patches back to the current version though).
(If you like I'll send you the Virus so you can delete it)

TTFN
