Sophos: Fake Norton antivirus is really a Trojan Horse
September 2008 by Marc Jacob
Hackers attempt to infect PCs of Googlers hunting for "free antivirus". IT security and control firm Sophos today warned internet users of downloading fake anti-virus products, following the discovery of a malicious Trojan horse that is posing as a free copy of Norton AntiVirus 2008.
Google adverts are being presented to internet users who search for "free antivirus", leading them to a professional-looking website that claims to offer an anti-virus product for download.
The website attempts to lure visiting computer users into installing a Trojan horse, Troj/FakeAV-AD, which will then present fake security alerts and urge users to purchase a "full version" of the software.
Sophos has produced a video demonstrating the risk to internet users.
