Zafi.D is a worm with backdoor characteristics, as it opens the port 8181 and waits for a file to be transferred through it. Zafi.D executes this file, which is usually other malware.
Additionally, Zafi.D impedes access to applications that contain the text strings reged, msconfig or task.
Zafi.D spreads via e-mail messages that pass themselves off as Christmas greetings. It also spreads through peer-to-peer (P2P) file sharing programs.
The Zafi.D Remover utility will allow you to easily get rid of the virus infection from your computer.
