You should not play around in the Registry unless you know what you're doing, even if you know it's related to a virus it could cause damage.

I suggest you download a program like AVG, The Cleaner or SwatIT and clean your computer.

In future, do not:

- Click on URLs which are advertised to you, either in channel or in PM (Private Message).

- Accept files from people you don't know.

- Open emails from people you don't know, or open email attachments.

You should also always have a working and up-to-date AntiVirus program running on your computer at all times, and if it has an "Auto Protect" feature, have it enabled.

Happy chatting!
