When you visit certain pages, users get a message that their computer is infected with the virus and offer to download antivirus. After installing the program steals personal data, or forcing people to pay for the registration of a fake product. Experts pointed out that it's amazing how many people are becoming victims of fraud.
Manufacturers of fake antivirus products use search engines to force consumers to buy this useless software. If a user searches a popular word or name of the resource, written with spelling errors in the search results are displayed links to scam sites. Once a user enters such a resource on the screen of his computer pops up a message box that the PC "damaged and corrupted" any malicious software. Then invited to install an application that will eliminate a nonexistent threat. On average, users pay for the download of a fake anti-virus about $ 50.
Fake antivirus programs are often associated with other malicious software, which remains in the victim's computer, even after the payment. During the research specialists Usenix Workshop found 11 thousand domains associated with the spread of false detection. More than half of counterfeit software delivered to PCs via advertising. Experts recommend to be cautious when a site offers to download some additional software, and not to download antivirus software from an unknown site, if you have one already.
