Also called rogue security software, scareware is software that uses pop-ups and other tricks to convince you that your computer is infected, and buying their software will eliminate the infection. This software typically does nothing at all, or actively damages your system, while the people that authored the software use your credit card information for their own purposes.
It is becoming increasingly challenging to tell the difference between legitimate antimalware and scareware programs. The best way for you to protect yourself is to install an antimalware program from a trusted vendor and keep it up-to-date. If you see a pop-up like the one above, close the window, and run a scan using your trusted solution instead.
