I opened an additional tab in Google Chrome and tried to enter a football site in my Favorite, but it seems to redirect me to another site with the URL: Virusdefense.info. A screen popped up that said “System at risk” and asked me to call a support number. I attempted to close the tab and was challenged with the options of: “Leave this page” or “Stay on this page.” Although I clicked on “leave this page” two times, it continued to challenge me with the same two options. Is there really a virus in my computer? Is my data like bank information still safe? If this is a fake message, how do I get rid of it from my system?

Virusdefense.info is a fake alert that can appear anytime on your web browser and block you from surfing the web properly. It is a scam that goes something like this: the user gets a pop-up in their browser that tells them that they are infected and says to call a number (toll free of course) to get virus removal support. Once the user calls this number they will be directed to a website that allows the scammers (*agents*) to connect to the PC. Once the scammers get connected they will show the user all the “infections” but in most cases they are just regular system files. In the end they start selling their expensive product claiming it is a good protection for your PC. In fact, Virusdefense.info pop-up is only designed to sell potentially unwanted program and it’s 100% fake although it looks like a warning from Microsoft.
