Fake anti-virus, also suggestively known as scareware, tricks you into paying money by pretending to find threats such as viruses and Trojans on your computer. If you pay up, the software pretends to remove the non-existent threats so you may not even realise that youve been scammed. This sort of scam is most common on Windows, with OS X a long way back in second place. Most of the viruses on the list are existing Android malware names, in order to add a ring of verisimilitude.”]
