About every 5 minutes or so a black dos screen pops up and disappears before i can make out what directory it is from. The screen is blank and is from the documents and settings directory but it disappears before i can read the rest of the directory location. Here is a copy of my hijackthis file. This problem does not seem to be causing anything to happen just annoying. Thanks for any help.

The "NetDetect" component of Norton's Live Update feature is probably the source of the DOS pop-up. Check the Live Update-related preferences within your Norton applications to see if there's a setting which allows you to modify the 5-minute auto-run interval.

It might also be listed in your Windows Task Scheduler; check there as well for a reference to NetDetect or ndetect.exe.

DMR, Thankyou for your help. I did what you recommended and it seems to have solved the problem. I had so many updates trying to run it slowed the computer to a crawl.

Glad we could help :)

Yup- that can definitely be a problem. A lot of programs that have an automatic update function don't even give you any notice that they're doing it, making it hard to figure out where the problem lies. This is especially true at Windows start-up, because many of the items that live in your system tray will do their updates when Windows firsts fires them up. If you're having slow start-ups, chances are you've got RealPlayer, QuickTime, your anti-virus program, and a slew of others all trying to "phone home" at the same time.
