The only likely way your system might have been infected with a worm
is if you have security vulnerabilities which you have failed to
patch.  Once you're infected the only safe way to recover is to wipe
the disk and reinstall; it's too easy for attackers to hide backdoors
in the system which will let them get back in even after you repair
the initial security vulnerability.
