AntiVirusPro (also know as AntiVirus Pro) is yet another imposter spyware removal tool. AntiVirusPro is generally downloaded and installed by the various Trojan programs or under other such malicious circumstances. Once AntiVirusPro is executed and installed onto a system, AntiVirusPro will launch itself on each Windows start up as well as generate erroneous warning messages and misleading scan results. This is the manner in which AntiVirusPro’s creators keep attempting to coerce computer users into purchasing the commercial AntiVirusPro version.
