Now, this is not the first time this is happened, but it is uncommon enough that it warrants discussing. When Antivirus 2009 is installed, it will install a Internet Explorer browser helper object called C:\Windows\System32\winsrc.dll. This program will automatically load when Internet Explorer starts, and when you visit certain sites, it will insert its own information into the web pages that are retrieved. Currently the information that is inserted into the Google home page and search results is a misleading advertisement for Antivirus 2009. The current text of the advertisement is:
Google TipsThe advertisement is actually one big link that if clicked will bring you to a page at the hxxp://microsoft.browserprotectioncenter.com/ site that says you are infected and should purchase Antivirus 2009.
Google has detected unregistered Antivirus 2009 copy on your computer. Google recommends you to activate Antivirus 2009 to protect your PC from malicious intrusions from the Internet.
The tactic being used by this Rogue is to trick the infected user into thinking a well known and highly trusted brand, like Google, is actually endorsing their products. In reality, though, this is just another scam being used to steal your money. If you are infected with Antivirus 2009, you should use the following guide to remove the malware for free. If you have already paid for the software, please contact your credit card company immediately and dispute the charges.
