There is a virus that is masquerading as antivirus software that is actually a Trojan virus. It is called Antivirus 2008 PRO. It looks like a popup that asks you to download the latest version of the antivirus software. Once you hit OKAY you are infected.
Be VERY careful when downloading any updates on your computer. Be sure that indeed it is from a trusted source and related to something you already have on your computer. When in doubt do not download. Better to be safe than sorry.
