Very slow computer. Virus?

Specs: Microsoft Windows XP Home Edition, 2.8 GHz / 223 MB
My computer recently has become very slow to start up, go to my home page, run programs, etc. I've scanned with AdAware, Malware Bytes, SpyBot, A Squared and my AVG antivirus, as well as Kapersky's on line scanner and removed everything found, but to no avail. Is there any help out there for me? Will supply a HJT log if needed.

Oh, also, I've tried chkdsk in both normal and safe mode and I get to a certain point and the computer restarts....leads me to believe it's a virus or malware that scans aren't finding.

You should scan your computer with Malwarebytes in Safe Mode. It should must be updated.
You should also delete all temporary files, temporary internet files, browsing history and prefetch.
You should disable all unwanted startup from startup list.
Start > Run > type msconfig > Start tab> and unchecked all unwanted startup from list.

You should also increase virtual memory of the computer and run Disk-defragment utility.
Now check.

If chkdsk doesn't complete, it's possible your HDD is going bad. Make sure you have backups of your data.

I have always used CCleaner and Windows Clean Up! to clear out temp files, cookies, etc. after each use (paranoid of ID theft) and I do defrag religiously (at least once a week). I recently shut down my unwanted startup items and none has made a difference. I strongly suspect some type of corruption or virus/malware infection that my scans are not catching.

I will try the Malwarebytes scan in safe mode and the smitfraud scan in safe mode and report back. Thanks for the responses.

223 MB of RAM is too little for XP, and other programs.

Computer Speed and Performance May Decrease

When you open, then close programs,
programs may not free up RAM memory.
That is called "Memory Leak".
Restarting computer will clear out its RAM memory.
OR
install more RAM memory.

Most Virus and Spyware scans are likely to work better in Windows Safe-Mode.
