Hi everyone, Tammy here.
Naive newbie

Chatting on Yahoo, met a fried (who turned out not to be such a great friend), anyhow, he sent me a file infected with a trojan virus.

The program he used is called Magic Pass, or Magic PS

Everytime I login to Messenger, it sends him a PM with my ID & password.
It is my undertsanding that it has also dropped in a keylogger
In addition, it has disabled regedit.
Everytime I turn my computer on it gives me an "error code #5", a feature of Magic PS

I found the website for Magic PS,and they brag that it is undetectable by most AV's. I removed the original file, but the registry has already been changed, and of course, I can not edit it. Re-installed messenger, doesn't matter

A plea to this guy only resulted in a "format your hard drive" response.

Am I out of luck for a viable solution besides formatting my drive? Any help would be appreciated.

By the way, I am fully aware of the stupidity, thought he was trustworthy.

Thanks gang, have a great day.
