winlogon seems to have a memory leak

Can someone help me fix a memory leak on my windows xp machine?  the machine would not boot at all even in safe mode.  i used winternals ERD program to get to a dos prompt and was able to del the pagefile, during boot up I would get an error message about low virtual memory.    This worked and I was able to reboot once and see that the winlogon.exe service was hogging all the ram.  it kept going taking more and more ram.  

any thoughts other than a full install.  I did try a repair early on in this process but that did not help.

I get errors about "low virtual memory" from spyware all the time.

On a machine with 256Mb of RAM your Virtual memory should be in the range of 256 to 768 Mb.

Get your system clean of malware and this error will go away!

got the system to boot after a third repair install.  Task manager is still showing that I am using over 600MB of Memory but no individual program seems to have a big chunk of it.  I currently have 256 of RAm installed.

Could it be that a program is not release the memory back for use?

I have msconfig set to start up nothing but I am afraid to restart.  I am scanning for viruses now and will try for spyware next.  I do not want to tuen it off for fear that it will not boot up again.  

Any thoughts as to what I can do?

For more information on spyware:

When you install XP be sure to install SP2 before you put the computer out on the Internet. It includes a firewall and popup stopper that are very helpful in dealing with spyware.  Additionally I refuse to build a computer without also installing antivirus and spyware stopper (resident). Both are available for free:

FREE Anti-Virus:

FREE SPYWARE install SpyBot and use Innoculate feature (I also use TeaTimer to protect my registry):
