From: Phil on 3 Jan 2006 00:00 My sister called in a panic today, as her 1.6Ghz 256 meg, 20gig drive, Dell PC is all but useless after working with Norton Anti-Virus 2004. The system is extremely slow, even taking several minutes to put icons on the desktop, and MS Word taking a couple of minutes. All far slower than before she did the following. Norton NAV 2004 subscription lapsed. She decided to install NAV 2006, so uninstalled NAV 2004. Installation of NAV 2006 failed when she ran it from their website (ordered on line), and directed her to a site to download symnrt.exe. She ran symnrt.exe without a problem. System then was very slow. Powered off and restarted with no change. Everything appears to work, but system is agonizingly slow. I had her check some things. CPU usage is very low, and memory usage appears fine. Wiped out all Symantec files I can find. No Symantec or Live Update programs to be uninstalled. What next? I forgot to check hard drive space, but will tomorrow. - Phil

Remove all Symantec files - do a search on your drive for "Symantec" or "Norton" 3. Defrag yourhard drive ** Anytime you remove a program and want to reinstall it you must do this step. ** Othewise you may reinstall some same files which might be corrupted. 4. Reinstall Norton AV. NAV is initially setup for corporate work when you get it. When you open it, click the "Options" Tab, click on "auto-protect". In the bottom section change the selection to "Scan files using smartscan". Just to the right of that you'll see a button named "Customize". When you click that it shows the extensions that will be scanned. If you leave it on "Comprehensive file scanning", you will be scanning all of your files all the time which wll slow down any system. I use NAV 2004 on one system and it works good.

Look for anything Norton/Symantec/LiveUpdate-related in Add/Remove Programs and remove it, assuming that her computer isn't using any other Norton/Symantec software. It could be that NAV has left some driver files behind. To get into the Computer Management window, right click My Computer->Manage. Right-click on Device Manager->View->Show Hidden Devices. Under "Non-Plug and Play Drivers" look for references to NAV or SYM, disabling each in turn (if asked, only reboot after you've done them all). You could try installing NAV 2006 and seeing if you can successfully manage it, then uninstall/reboot/SymNRT again and buy Eset's NOD32 as it doesn't gunk up the system :-) Is the computer still that slow in Safe Mode? If you open on the Task Manager, once it has booted and got past the initial programs after logging in, is the "System Idle Process" getting most of the CPU (>95%)? Have you tried disabling any firewall/anti-spyware software? Did your sister, in her panic, install any other anti-virus software? Are there any errors or warnings in the Event Log, in the Computer Management window?
