Antivirus Plus is another rogue pretending being Microsoft’s recommended anti-malware tool. The trojan tries to mask the website in the hosts files, pretending it is legitimate microsoft website. A clear sign of AntiVirus Plus is entry like this in the HOSTS file : 66.249.93.104 security.microsoft.com This entry should be removed once noticed. These fake Antivirus Plus alerts are provided by trojan installers coming through peer-2-peer networks, infected websites and bundled shareware products like Video codecs. Once free version of the AntiVirusPlus is installed and run, you will be informed about various spywares and trojans in your PC that no real security expert ever seen. They are all fakes! After scanning they ask to pay for “full” version of the software which “can remove” the parasites. After paying to them, you will never hear about them again and wont get any software. At least no useful one. Sometimes they just use credit card details couple more times to make a bigger hole in your pockets in these difficult times. You should not believe owners of this scumware and remove AntiVirus Plus from your PC as fast as possible instead. The reason for this is that such software might create backdoors for real parasites, that might use your PC to send spam, show other popups or try to get credit card infos and send them to criminals.
