My wife's month old Dell Inspiron ordered with Windows XP will not shut down properly, sometimes. When it does not, a window opens and something called "_GD_Crawl" has to be force quit. A search for this file or program returns nothing. The computer has had two episodes of slowing way down, but a reboot has corrected that. The "_GD_Crawl" did not appear those times. I only see it after returning to the computer after thinking it had been shut down, but it had not. This only happens sometimes.
Eset Nod 32 was installed right out of the box after removing Norton. It does not indicate any infections.
Any ideas?
