Aliases: Win32/FakeAV.AQD (CA) FakeAlert-CP.dll (McAfee) Mal/Behav-304 (Sophos)

Summary

Trojan:Win32/FakeIA.I is a trojan that displays fake warnings of spyware or malware infections in an attempt to convince the user to install rogue security products. Trojan:Win32/FakeIA.I embeds a fake virus warning window in each web page that the affected user browses. This warning attempts to convince the user to download additional files.
 
Special Note:
Reports of Rogue Antivirus programs have been more prevalent as of late.  These are programs that generate misleading alerts and false detections in order to convince users to purchase illegitimate security software.  Some of these programs may display product names or logos in an apparently unlawful attempt to impersonate Microsoft products. 
Manual removal is not recommended for this threat. To detect and remove this threat and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742).
