Ok a virus i downloaded is shitting up my computer. heres what happend:

1.I was talking to a friend on AIM and I saw a message from her saying "interesting (an ip address)
2. I clicked the link and it was prompting me for a download. I downloaded the file and ran the program.
3. Next thing I know, I'm talking on AIM and that message popped up and made it look like I typed it. Its said: "can you help http://192.168.0.3:8180"
4. That IP address is mine so apparently this virus sets up a server using your IP and auto. adds random messages in AIM that provides your IP which contains a prompt for downloading the virus. I am running through scan disk but I have to quit nets. for it to do it properly.
5. I am getting current pop window messages saying "Windows Socket Error (10048) API 'Bind'"


What should I do? I don't have any type of virus scan (i know you can smack me upside the head a little later.)

HelP!

PM or find me on AIM if not on AO
