Malware:
Malware is the abbreviation of "Malicious software" (malware), term that encompasses all kinds of program or computer whose function is damaging a system or cause a malfunction code. Within this group we can find terms such as: virus, Trojan (Trojan horse), worm (Worm), Dialers, Spyware, Adware, Hijackers, Keyloggers, FakeAVs, Rogues etc...

Among the most prominent are the (counterfeit antivirus) FakesAVs and FakeAS (counterfeit Antispywares) in InfoSpyware we have been carrying since 2005 a listing of the majority of these and visible in counterfeit antivirus - list False antivirus listing
