It would appear that you have been infected either by Sasser or Blaster, I can’t remember which.

Download and run - avast! Anti-virus Cleaner ensure that your OS is fully up to date to close these exploits.

Yep, follow DavidR’s instruction. Do you have 3rd party software firewall? If no, download one immediately(i.e. zonealarm).

And you can update your OS if it is Windows via Windows Update, link: http://windowsupdate.microsoft.com
