Antivirus Security is promoted as legitimate security tool, but it’s yet another scam. AntivirusSecurity uses various ways to infect computers: it is installed by trojans and other malware programs; it also installs itself when user opens malicious spam message or visits infected website. Antivirus Security is very dangerous parasite. It is able to interrupt other applications and crash the infected system. The purpose of AntivirusSecurity is tricking people into purchasing a license of this program. Don’t be misled by Antivirus Security! The license or full version is just a bait to get your money.
