Yahoo Messenger Virus Attack

It is one of the most powerful Trojan /virus I have ever seen… While I was working, one of my friends PMd me and gave me a link http://www.nsl-school.org [Please don’t click this link] If your computer is infected with this virus ” It will send the nsl-school.org url to all of your friend list in yahoo messenger using your ID . So with in few hours many of your friends will get infected with it.

I don’t know what’s the actual target of the idiot who created it. May be to advertise his site or to steal very imp data from your computer. I resolved the problem manually from 2 infected PC’s. Just go through the below steps carefully.

What are those links ?:

Nsl-school.org or other (Do not open this url in your browser).

If you are infected with it what is going to happen ?

1: It sets your default IE page to nsl-school.org, you can’t even change it back to other page. If you open IE from your comp some malicious code will automatically executed into your computer.

2: It will disables the Task manager / reg edit. So you can’t kill the Trojan process anymore.

3: Files that are gonna be installed by this virus are svhost.exe , svhost32.exe , internat.exe.you can find these files in windows/ & temp/ directories.

4: It will sends the secured & protected information to attacker

Warning : Better not to open any unknown url from your Computer. Even its from your friend.
