Windows 7 - Over One Hundred Thousand Websites Infected.

Security researchers have detected a new mass injection attack that has compromised over 130,000 websites so far. A rogue IFrame is used to exploit visitors and infect their computers with a banking trojan.
The attack apparently began in late November and has grown at a steady pace since then. A Google search for the malicious frame performed two days ago revealed 125,000 results, while a new search today resulted in 131,000 hits. On the other hand, Yahoo! reports over 300,000 results for the same query.
