GcasServ.exe bug?

[Max Burke]

Can anyone tell me what GcasServ.exe function is in MSAS?

It appears to have a bug in that every 2-3 seconds on my computer it uses
100% of the CPU for about 5 seconds.

It does have a minor effect on other programs that are running in that the
stall or slow down for 1 or 2 seconds. (mostly games or when I'm editing an
image file in programs like Photoshop Elements, Paintshop pro, etc....)

I have tried stopping it in XP's task manager, and MSAS still runs as normal
and I no longer have the delays in other programs...

Googling for info on it just comes up with info that it's part of Giant
Anti-spyware/MSAS and it's up to the user to decide if they/I want to run
it.

SystemInternals Process Explorer (http://www.sysinternals.com/) doesn't tell
me much about what it's doing..

If it's not needed how can I stop it from starting?

Maybe I'll try renaming GcasServ.exe and see what happens when MSAS
starts...

I think it is part of what implements real-time protection.

You might try, as a test, implementing the workaround paragraph of this KB
article on your system, to see if that fixes your performance impact
problem:

http://support.microsoft.com/kb/892375 End users may be prompted to allow or
block administrative actions that originate from a central management tool
after they install Windows AntiSpyware (Beta) on a computer that is managed
by Systems Management Server 2003

That should effectively turn off real-time protection.

The other thing(s) to try would be an update install (control panel, add or
remove programs, change, update)-- to see if this is an issue with the
specific install, rather than generic to your hardware or combination of
drivers/software.

If that fails, an uninstall/reinstall is also worth trying.
