My Norton anitv has detected web.exe in c: as a trojan horse. It cant be fixed. I've downloaded Ad-ware and Spyware, but they found nothing. The trojan is still there. How do i get rid of it?

"Discovered in mid-December, the new Gokar Worm is spreading around the Internet. Outlook and Outlook Express users, users of mIRC (an Internet Relay Chat program), and anyone connected to an IIS Web server are at risk. The worm spreads via email when a user double clicks on an attachment (which will have an extension such as .exe, .com, .bat, .pif, or .scr) to a message sent by the worm. Gokar installs a file named "Karen.exe" and then sends itself to every address in the Outlook or Outlook Express address book. mIRC users' systems can become infected if the worm has infected a system in the same discussion or channel. Downloading the worm from IIS web sites is still another way this worm infects systems. If Gokar infects an IIS Web server, it modifies the home page to display the message "We are Forever" and offers a hyperlink to download a file (Web.exe) infected with the worm. The worm becomes active every time the infected system boots. If your system contains a file named "Karen.exe" Gokar has in all likelihood infected your system. Keeping your anti-virus software up to date and refraining from opening suspicious attachments or downloading files such as Web.exe from IIS web sites are good preventative measures."
