Company recently installed Symantec Corportate Antivirus package. Works quite well, updating systems regularly. However, some users are reporting a slowness in their system operation. Could this be related to the client part of the virus protection program?

Did some more research and found the program was set to scan the mapped drives whenever a network file is open. Removed the network setting, leaving the workstation alone. Server will monitor network files. Thanks for your input. Greatly appreciated.

I have found that certain applications the users are using cause slow downs when using any antivirus program.

It happens when the antivirus program is set to scan file extensions that certain programs use.

One place had terrible slowdowns because the accounting software they use has there data files in *.DAT extensions. The norton antivirus scans the whole file each time it is opened causing the application to run very slowly. Why? The accounting files were huge and it has to scan them each time the accounting program opens them.

Once I had found that, we configured the norton corp. av program to not scan those file extensions.
