Symantec Antivirus and WINLOGON use 50% CPU time on booting

[Raqueeb Hassan]

Hi Everyone,

When I start my Celeron PC + 256Mb RAM, a Windows 2000 professional
machine takes lot of time to boot, lot of disk activities and ...
applying the system security takes like forever. When I switch to Task
Manager, everytime I find WINLOGON process is taking 40-60% CPU time
for that first 46 to 49 seconds. Then it gets back to normal mode. Does
it have anything to do with windows SFC? If I uninstall my Symantec
Antivirus, the problem goes away. What can be the reasons? Without
Symantec Antivirus, I'm dead!


TIA

Use Avast Anti Virus instead, it's free with registration and uses less cpu
time.

Thanks for that. But there has to be some solution with this NAV.
Otherwise, it wouldn't be a great antivirus company

I'm using SP4 with Windows 2000. While googling I found similar problem
without proper solutions. How on earth can that be?

It would be helpful if you posted what version of SAVCE you are using. For
example, if you are using version 7.x or 8.x, I would highly recommend that
you upgrade to 9.x or 10.x. (Only mentioned because Symantec no longer
performs quality assurance on definitions for 7.x. 8.x is nearing end of
life.)

Is that on boot up or continuously?
NAV is just scanning and checking for updates while WINLOGON is a part of
the Windows Login subsystem.

The winlogon.exe file is located in the c:\windows\System32 folder. If it
is located somewhere else, then winlogon.exe is a trojan. If you find this
to be the case, then you will need to run a complete virus scan . . . and
possibly more - here is an example if you have Backdoor.Graybird or possibly
some variant.

I'm using Symantec Anitvirus 9.x.

No, it only happens during boot up. Well, I did a complete scan two
days back. The winlogon is still in c:\windows\System32 folder. I guess
I've to switch to McAfee or Avast. If I uninstall my Symantec
Antivirus, the problem goes away.
