Antivirus Trigger Removal Guide and Information

Do you know what Antivirus Trigger is?

Antivirus Trigger (AntivirusTrigger) is a vicious rogue anti-spyware program known to be installed onto your system without notice until you start getting popups or error messages. Antivirus Trigger may be installed through a Trojan such as, Zlob.Trojan, Vundo Trojan or even Trojan.Downloader.

Antivirus Trigger is not one of those programs that you do not trust to scan your computer for parasites because even though it displays many parasites in the scan results, they are probably not even present on your system. Antivirus Trigger is also known to display many error messages that usually say something similar to "System Alert: your system might be infected with malicious software". That message is probably total BS.

In non-techie terms:
Antivirus Trigger should never be installed or purchased under any circumstances. Antivirus Trigger was probably created by a group of hackers with the main purpose of monetary gain from gullible computer users.

    Your article was very helpful for me.
    I used Antivirus Trigger Automatic Removal Instructions and I think
    that my computer is OK now.
    The only problem I can see is the following:
    In the Internet Explorer there is a toolbar called "Security toolbar" with "PC Security Level", "Remove malware" & "Scan for spyware" buttons.
    Is this normal or is it from Antivirus Trigger?
    Please help me because i don't know what to do.

    Thanks for ypur help.
