Using Google chrome, everytime I open it up, I get a 'Trojan Horse Blocked' alert, says the infection is HTML:Iframe-inf and that the process is either:
http://www.facebook.com/plugins/likebox.php
or
R2.ace.advertising.com/
Both with a long string of code afterwards (that includes the http://www.singletrackworld.com url)
I thought this was just for STW, but it seems to be any web page I open in Chrome? I've done a full scan with Avast and it didn't find anything, any ideas what I should do next?
Again, just tried something else, opened Explorer and got the same error/alert message... WTF is going on?
