Is malicious software that tricks computer users into visiting malware-infested websites. Also known as deception software, rogue scanner software or fraudware, scareware may come in the form of pop-ups.
These appear as legitimate warnings from antivirus software companies, and they claim your computer’s files have been infected. They are so cleverly done that users are frightened into paying a fee to quickly purchase software that will fix the so-called problem. What they end up downloading, however, is fake antivirus software that is actually malware intended to steal the victim’s personal data.
