This page on the Symantec website is devoted to this very recent
("Discovered on: October 28, 2003") trojan and removal instructions
for eliminating it:

The backdoor.hogle virus may be so new that you will have to
remove it manually, per Symantec's instructions.

If you don't currently have an antivirus program, you can use
one of these online scan services to check your system for other
viruses. You can also try to use them for assistance in removing
the backdoor.hogle virus, but since it is so new, they may not be
updated to handle it yet:
