Trend Micro – Creates new FAKEAV standalone removal tool

QUOTE: Fake Antivirus (FakeAV) threats have been rampant in the past few years. Various FAKEAV variants have infected millions of PCs and are continuously spreading worldwide. One reason why FAKEAV infections have become well-known to users is because they have visual payloads. Variants of the malware family often display pop-up messages telling users that their machines have been infected. This may cause panic among users, pressuring them to purchase rogue antivirus applications in the hope of resolving the issue. Users, however, should never purchase antivirus software from unknown sources.
