Searchers beware: Those photos of celebrities or funny cat pictures that turn up in your Google image search results might not be photos at all, but fake antivirus alerts. Evidence appears to indicate that a similar scam to one we blogged about last November may be working its way up the Google food chain into other forms of search results.
Throughout the day we’ve been looking for links such as these; Each malicious URL we found funnels the browser into the same fakealert, which itself leads to the same rogue antivirus product. Each time we revisited the site, we ended up with what was essentially the same equally nasty rogue antivirus application, sometimes in a different skin, sometimes with a different name. Early in the day we were pulling down something called Total Security. By the afternoon, the tool’s name had morphed to become Security Tool.
The rogue’s behavior on an infected system is obnoxious in the extreme. It hides the desktop by covering everything over with its own wallpaper, and blocks your ability to right-click the desktop, so it’s more difficult to revert the desktop’s appearance by changing your Display Properties settings. It also disables the scroll wheel on the mouse, then blames that behavior on a massive infection it claims has taken over your PC. It prohibits most Internet-capable applications, or even tools like the Task Manager, from running, in the guise of its “firewall” component. Of course, it’s all smoke and mirrors, an attempt to convince you to spend from $50 to $90 on completely ineffective, utterly useless former-Soviet snake oil.
