Could you go to the Event Viewer in Administrative Tools in the Control Panel and post the exact error message that will appear.

Here's a link to a description of the error: http://aumha.org/win5/kbestop.php#0x21a

Generally this appears to be a problem with the security features of XP (or the services that run them).

I'd suggest another scan - try this free, online one if you can get it done: http://safety.live.com/

If that doesn't fix it, you may be facing a repair or reinstallation of XPPro - so I'd suggest backing up your valuable data right away.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Does anyone know whether the http://safety.live.com scans and such will work under Safemode with Networking? If so, you could try that.

It requires download of Active X components but it's worth a try.

When did this problem begin and can you start in safe mode with command prompt?

If you can, and the problem began less than three weeks ago do the following:

Start the System Restore tool at a command prompt
1.Restart your computer, and then press F8 during the initial startup to start your computer in Safe Mode with a command prompt.

2.Log on to your computer with an administrator account or with an account that has administrator credentials.

3.Type the following command at a command prompt, and then press ENTER:


4.Follow the instructions that appear on the screen to restore your computer to an earlier state.
