MegaVaccine
MegaVaccine is a rogue anti-spyware made in Korea. MegaVaccine spreads via Trojans. MegaVaccine can also be downloaded from malicious websites by unsuspecting users. MegaVaccine will display alarming pop-ups and security alerts to convince a user that his/her machine is infested with malware that can only be removed with its "full version". The "full version" of MegaVaccine does not exist and this application can neither detect nor remove any computer malware. MegaVaccine should never be purchased.
