System Performance with McAfee

[Mighty]

I have a network with roughly 60 nodes and use a McAfee solution of ePolicy Orchestrator with Virusscan and Anti-Spyware. However, several users are complaining in relation to the performance of their client PC's. To check if the problem was related to the Anti-Virus I uninstalled the software and the login time went from 4 minutes down to 20 seconds.

Do all anti-virus products place the same performance hit on a PC. From looking at their website NOD32 claim to use much less system resources which should imply improved computer performance.

All opinions welcome. Just trying to decide if it is worth my while switching solutions.

Mcafee and Norton suites are now becoming notorious for their heavy use of computer resources! Indeed, Nod32 is in my opinion a better anti virus and much lower on resources!

If you download this utility below and run a scan you will see what I mean when checking the 023 entries which McAfee creates as a run service in Windows which uses up so much of your computer resources!


However, Norton, like Mcafee are also notorious to uninstall , I wrote a doc on this on how to uninstall these!

Because of the problems encountered by many posters to this and many
other forums I have decided to write a thread on how to remove Norton
anti virus!


This guideline can also be used for the removal of McAfee or any other
anti virus program!


open Norton anti virus, click about, and obtain the version of Norton
anti virus you have, should be a year like 2002 etc!


You will need this to determine what version you have if you need to
use the Norton uninstallers!



Please download these uninstallers for whatever version of Norton
below and have them ready if needed!


Download them to somewhere you can find them like your desktop!




Uninstall Norton Anti virus. USe Norton's knowledge base.


This link below for Norton 2003-2007

This link below is for Norton 2000-2002

Before uninstalling Norton do these instructions first!



go to start/run/type msconfig/click ok/tick the radial dial selective
startup/click the startup tab/ uncheck any boxes to do with Symantec,
Norton and live update!

then click ok and then exit!



Also do this and disable any running Norton/Symantec services!



Click Start > Run > and type in:

services.msc

Click OK.

In the services window find Winlogon Notify: Automatic LiveUpdate Scheduler
Right click and choose "Properties". On the "General" tab under "Service
Status" click the "Stop" button to stop the service. Beside "Startup Type"
in the dropdown menu select "Disabled". Click Apply then OK. Exit the
Services utility.


Note: You may get an error here when trying to access the properties of
the service. If you do get an error, just select the service and look
there in the top left of the main service window and click "Stop" to
stop the service. If that gives an error or it is already stopped, just
skip this step and proceed with the rest.



Then disable all of these services by repeating the above!



These are optional, there maybe others not mentioned here, disable
whatever Norton/Symantec you find!


Note: you will alos do this if uninstalling McAfee or any other anti
virus!


Automatic LiveUpdate Scheduler
Symantec Event Manager (ccEvtMgr) Symantec Settings Manager (ccSetMgr)
Symantec Lic NetConnect service (CLTNetCnService) IS Password Validation
(ISPwdSvc) LiveUpdate
Norton UnErase Protection (NProtectService) -
Speed Disk service - Symantec Corporation -
Symantec AppCore Service (SymAppCore)



Then go to add/remove in control panel and click to remove Norton!


If this fails, then run the uninstaller for the version you have!


If you still have problems then post a hijack this log to the relevant
forum and await instructions!
