Is your network very slow while Symantec endpoint protection is enabled?

Services for Real Estate Pros with Technology Solutions by N.K.Narula


What is endpoint protection doing to my network that will be slowing software over the network.  I have setup exceptions for the program files folders of the programs in question and the shared network drive.  Also i have setup exceptions for the myob database file exception which is .myo and the other program affected which is .mdb.

The problem goes away when we disable the antivirus shield on the client computers.

How can i fix this issue?


Change Settings | Configure Antivirus and AntiSpyware Protection | File System Auto-Protect

File Types change to selected

Options | untick Scan files on network drives

Advanced | Scan when a file is modified

Floppies | untick if your machines have no floppy drive |


Change Settings | Client Management | Schedules Updates

Change the Frequency to daily : and select a time ( lunch is usually a good time )


Scan for threats :

If you have a scheduled scan you may want to tune the settings for better performance


Other things to note , if you have SEP installed on servers you may want to add exceptions for certain services such as Domain Controllers , SMS , WSUS , SQL and other applications like Email.

If clients have local copies of their emails , outlook , notes , groupwise you may want to exclude this directory from threat protection.

incidentally : MR3 is the latest release of the software you should be able to download from symantec's file connect website :

It gives greater performance that previous version which may also help.

Please Note:

My website is being overhauled.

I spent hours just working with new technology and really got it pretty fancy, but it was soooo convoluted with stuff that it's time to do a redesign.

It will be up at the end of the November so please make a note of it so i can start posting Q&A up there!!!

I had a problem running Symantec. I called Microsoft, which you can do if you own a legal copy of windows, and they told me that... in a nutshell... that if you are running more than one anti-virus program it will seriously slow down your computer. I got rid of all anti-virus software and began to use the Microsoft free antivirus software downloaded from and my computer never worked better.... until I bought a Mac. :-)
