Brief Description 

    

Trifor is a Trojan that does not have any damaging effects that spreads via the Internet. In order to do this, it exploits the iFrame vulnerability in versions 5.01 and 5.5 of Internet Explorer.

This Trojan is code written in HTML, which is included in the contents of a web page. When users visit this site, the Trojan is automatically downloaded to their computer.

Then, Trifor changes the Home page of Internet Explorer to the web page that contains the virus code.

Visible Symptoms 

    

Trifor is difficult to recognize, as it does not display any warnings or messages that indicate that it has infected a computer.
