Microsoft Kernel Patch [Q811493] Slowing Down Windows XP Systems
Microsoft is said to be looking into problems that some people have reported after installing a security patch that was issued last week. The patch - which was designed to stave off a buffer overrun that could allow attackers to elevate privilege permissions on users' machines - ended up slowing some users' systems to a crawl.

It seems that disabling your antivirus auto protect feature fixes the problem, but this work-around means that you patch one hole (the kernel) and opening up another (no auto-protect AV scanning). People have reported that this happens with Norton, McAfee and EZtrust Antivirus.

If you are having slowdown problems, you can also remove the patch for now, it is listed in Add or Remove Programs and called Windows XP Hotfix (SP2) Q811493. Hopefully Microsoft will fix the patch sooner rather than later. When you remove the 811493 patch, you could be prompted that the removal will cause the 814995 patch not to function, this is a flase "alarm", just uninstall 811493.

In some cases the patch will not be listed under Add or Remove Programs. In that case, system administrators can use the Spunist.exe utility to remove this patch. Spuninst.exe is in the %Windir%\$NTUninstallQ811493$\Spuninst folder, and it supports the following Setup switches:

/?: Display the list of installation switches.
/u: Use unattended mode.
/f: Force other programs to quit when the computer shuts down.
/z: Do not restart when installation is complete.
/q: Use Quiet mode (no user interaction).
Lets hope that Microsoft gets this patch fixed ASAP.
