Hey Im a newb just wanted to report I am getting the same problem after the update, but also as Yahoo! is my home page, anytime I simply click to yahoo.com, it comes up and states a Trojan horse was found !
file name-
http://m.www.yahoo.com/\{gzip}Malware name- JS:ScriptIP-inf [Trj]
Malware type- Trojan Horse
VPS version- 091227-0, 12/27/2009
Kinda freaked me out at first, but I'm hoping this is related to the issue on this thread.
I downloaded the Malwarebytes' Anti-Malware program and found 0 objects out of 97851.
I use firefox but it does the same on IE.
