Do you know what Antivirus Security is?
Antivirus Security (AntivirusSecurity) is virtually the same as other rogue anti-spyware programs such as Antispyware2008, AntiSpyware Expert, Internet Antivirus, Antivirus 2008 and Doctor Antivirus 2008. Antivirus Security facilitates numerous tactics such as fake popups and system scans to get you to purchase the full Antivirus Security program. Do not fall for this trickery. It will only end up making you upset because you will not be able to get your money back for a useless program.
In non-techie terms: Because Antivirus Security does not remove spyware or for that matter, detect spyware on your system, it should be removed and never purchased. Antivirus Security, in some cases, installs from a Trojan infection which may be obtained from a malicious site or fake video codec download.
