Antivirus 2009 certainly looks like the real thing. Very well done screen warnings of virus and trojans, which are false, remember not to click on any of these pop-ups. 

Researchers at TrendLabs have discovered a new set of rogue antivirus software circulating in the wild. Based on initial analysis, these threats arrive mainly via spammed email messages that contain a link to a bogus celebrity video scandal, although we have also received reports that the said link is also circulating in instant messaging applications and private messages in social networking Web sites.

RENOS Trojans are known to have very visual payloads that may further alarm users (for example, they modify the system’s wallpaper and screensaver settings to display BSOD). Thus, users may be more convinced that something’s wrong with their system, not knowing that their new software is the one causing it. (From: http://forums.mcafeehelp.com/showthread.php?p=526322)

Steps to take: If you are using Vista: Close all pop up windows, some you will not be able to close, go to Microsoft.com and search for Safety scanner. Run Microsoft’s online Safety Scanner and make sure your computer is up to date. I am finding that AVG is working better then Macafee. 

Do not click on any of the pop ups! 

Make sure you have good anti virus software. AVG 8.0 from download.com for example.
