My HJT Log can be found at the end of this history:

I'm running WinXP, SP2. I recently downloaded and installed McAfee Security Suite which is offered free by my ISP (Comcast). For years prior, I used Norton AV and never had a problem with it. Since my NAV subscription was running out, I went with McAfee. I removed NAV completely using the Norton Removal Tool, downloaded and installed the McAfee Security Suite. There are no incompatible programs running that would interfere with McAfee Virus Scan. Since I also have an AOL account (rarely used), the AOL spyware program was active when I downloaded McAfee. The McAfee tech told me it was incompatible with McAfee and I needed to uninstall it, then uninstall McAfee because of possible corruption, and reinstall a clean copy. I did so. The McAfee protection status indicates it is active, but the scan feature has the following problem which the McAfee techs have been unable to resolve. They said Microsoft has a solution for this problem and told me to contact Microsoft.

The problem:
When running a complete scan of my system using McAfee Virus Scan (which also scans for spyware and malware), the scan proceeds uninterrupted until it reaches a point somewhere around the 110,000 file mark. That's when Windows abruptly shuts down and I get the following screen:
——————————————————————————————————-
"A problem has been detected and Windows has been shut down to prevent
damage to your computer.
PAGE_FAULT_IN_NONPAGED_AREA
Tech Information
***STOP: Ox00000050 (OxFFFFDFF8, Ox00000000, Ox80550211, Ox00000000)"
——————————————————————————————————–

When I run McAfee’s Free Online Scan, which scans only for viruses and not for spyware or malware, the scan completes without interruption and no viruses are detected.

I downloaded and ran the free version of Ad-Aware 2007 and within a minute of it's scan, I got the same Stop error and Windows shut down. I started back up again and ran a free scan of Registry Optimizer…….WHEW! It didn't even get started before the Stop error hit again. I rebooted and uninstalled BOTH programs immediately.

I cleared the cache, cookies, history, temp files, etc…..no help. One of the MS Windows techs in the XP newsgroup said it’s probably a driver problem which generates that Stop Error screen since . He had me access and unearth every bit of possible information in "%windir%\system32\drivers" by showing ALL hidden files and folders, ALL file extensions, ALL protected operating system files, and the contents of ALL system files. I then checked the attributes to search for hidden attributes (HA) as well as product info, company and date. I found no such HA or other suspicious files. All files had company names and other data.

Then someone else (not a MS tech) said, “By the way that error about a page fault in the non paged pool can only come from a driver because non paged pool is where they exist.” But, an MS MVP Tech immediately countered by saying, “Not *only* from a driver…..see here:
http://www.microsoft.com/technet/prodtechn…3.mspx?mfr=true
"Faulty hardware, a buggy system service, antivirus software, and a corrupted NTFS volume can all generate this type of error."

So, here I am because some very nice person directed me to HijackThis to help solve my problem. Bottom Line: Virus scans alone complete without incident. Full scans abort the system into the Stop Error Screen. I have no idea what the heck is happening and I really do need to clean up my system.

I am a computer end-user, not a tech in any sense of the word, and my technical knowledge of the computer's system is terribly limited. HELP PLEASE! THANKS SO MUCH! Here’s my HJT Log:
