Apparently people are uploading malware to users computers in order to
modify ads displayed on websites they visit with their own ad.
"Techshout.com reports that a new, deceptive Trojan Horse program has
surfaced. The program is engineered to produce fake Google ads that are
formatted to look like legitimate ones. The ads are incorporated in
Google AdSense, the program that lets website owners display ads from
Google's list of advertisers. The Trojan Horse apparently downloads
itself onto an unsuspecting computer through a web page and then
replaces the original ads with its own set of malicious ads." –
