It appears that a trojan, Trojan.Qhost.WU, causes an infected machine to redirect Google ad requests to a roque server.

The infected machine has an altered 'hosts' file which redirects the page2.googlesyndication.com hostname to a third party hostname.

New threat reported by Yahoo! News etc. is spreading:

"Advertisements placed by Google in Web pages are being hijacked by so-called trojan software that replaces the intended text with ads from a different provider, Romanian antivirus company BitDefender says.

The trojan redirects queries meant to be sent to Google servers to a rogue server, which displays ads from a third party instead of ads from Google, BitDefender said in a statement."

Anti-virus vendor BitDefender recognizes this Trojan horse as Trojan.Qhost.WU listing the description document here:
bitdefender.com/VIRUS-1000239- ...

The good news is that Google has canceled these malicious accounts.

It appears this is the week of Orkut, YouTube and AdSense related security vulnerabilities:(

The one thing that has me scratching my head is with the whole 'Google has cancelled these malicious accounts' part. If I have an edited HOSTS file how is Google going to know if my computer is redirecting all of the ad requests to a 3rd party site?

Oops, and the week of Google Toolbar, Google Web Toolkit Benchmark Reporting System and Gmail vs. IE cache vulnerability too.
