anti-MSblast program run, still evidence of worm in system?

Sorry if this has been covered and I missed it. We ran the
anti-worm program-- which said the worm was found and
eliminated. We downloaded/installed the patch. Why when we
search files using the search function in XP does it
appear that there's a file related to the MSblast worm:
msblast.exe-3646SF... C\WINNT\Prefetch with a date and
time? This has occured on both of our infected computers.
When we search the directory through dos as outlined in
one of the instructions sheets on this website, however,
it says the virus/worm isn't in the system.

Any idea what all this means, and how to straighten it
out? Thanks.

Prefetch is like a caching folder, so if you use a
programme quite often windows will load it up automaticly
from this prefetch folder. Best thing is to delete it from
here and it should disapear for good if the worm has
successfully been removed.

Cheers
