Windows XP SP1 slowdown

[Robert]

I am running Win XP SP1. Since I updated, I have been
experiencing a severe slowdown in performance. Programs
take forever to open. Any suggestions or fixes?

Robert;
Does this apply:
Some computers have issues with 811493 causing a slowdown, others do
not.
The issue seems to be a conflict with Windows Update 811493 and
antivirus applications.
Similar issues reported with McAfee, Norton, EZ Trust and possibly
others.
Uninstall 811493 from Control Panel Add/Remove Programs.
If a warning comes up about other applications, ignore it.
Uninstalling through Add/Remove Programs is far better than System
Restore to remove an application or fix.
Microsoft has stated they are working on the cause, so hopefully we
will get some definitive solution real soon.
Watch this link for status changes on this patch:

This may apply if you recently installed Windows XP Service Pack 1:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q815411

Otherwise:
Run an updated virus scan.
Run Disk Cleanup checking all boxes except "Compress old files"
Run Defrag.
If you have file sharing software such as Kazaa, disable it.

Run Ad-Aware (free version) or Spybot to check for spyware:
