811493 Symptoms From Spyware/Antivirus?

[JimC]

After a couple weeks elapsed, I thought my XP Pro system was one of the
lucky ones that are not affected by the 811493 update anomalies.

However, everything suddenly began to slow down. Acrobat Reader and Word
startup times jumped dramatically, as did desktop/menu/windows refreshes,
mouse navigation, shutdowns, etc.

I disabled my antivirus "auto protect" feature and let Spybot Search &
Destroy remove every spyware/adware object it found. Suddenly, good XP
performance returned, even after I turned "auto protect" back on.

Was my experience related to 811493? Is the cause of slowdowns as simple as
811493 triggers conditions which cause antivirus software and/or
spyware/adware to interact or function in a way that hogs CPU cycles (like
having 3 or 4 NTVDM programs spinning through loops looking for input
events)?

It does sound a lot like what I have heard others experience, but typically
it happens right after installing the update and then AV getting a hold of
it.

Go to your Add/Remove Programs and uninstall 811493 and I think you will see
your computer speed back up.
p.s. It was not a critical update and Microsoft is working on a fix.

Duh??? My point was, I fixed slowdown without uninstalling 811493, which
suggests that 811493 may be getting the blame for too many slowdowns, or
that the thing which triggers 811493 slowdowns is precipitated by specific
combinations of AV software with spyware/adware.

Furthermore, I rather doubt that you should represent yourself as a
Microsoft spokesperson (i.e., see your p.s.).

Yes

Something of the sort. MSoft have confirmed that the problem exists,
that it is related to having various real time AV running, but not just
why. At present do without either the AV or that fix. It is only
really relevant in a corporate situation, as one of the things that
would stop a malicious user who could logon as limited user being able
to promote himself into full control

Its a combination of the 811493 patch and the AV software (maybe some
others) that causes the slowdown. Get rid of one or the other, and it goes
away. This patch has been downgraded to a Recommended Update.

And is that because this fix diddles with the
task priorities? - RM
