Hi!

I hope I am posting this in the correct group! Some time
ago, Norton Anti-Virus found on my computer the file
taskmangr.exe was infected with a virus, and it
automatically deleted the file. So now whenever I turn
on my computer, I get an error message stating that this
file is missing. Am I able to re-install this particular
file? ( FYI: I have no Windows disks; none came with my
computer) I am, however, still able to access the Task
Manager by hitting ctrl+alt+del and choosing Task Manager
from within the Windows Security Box that pops up.

Thanks for any help!
Jennie
