Will Antivirus bring down the performance of SAP System

[Former Member]

I have installed SAP Netweaver in my PC.

During my installation of SAP Netweaver, it insisted to disable the McAfee Antivirus running in my machine to continue.

Also I observed running the SAP Netweaver installation with McAfee Antvirus slowing down the performance.

Hence,

1.Can anyone suggest is it advisable to run Antivirus in the machine that contains SAP softwares?

2.Will there be any impact in performance due to Antivirus running in SAP software machine etc.

3.If Antivirus can run on the SAP software machine, Do we need to include any parameters to not to SCAN SAP supporting software files?

4.Is there any specific antivirus can be used in a SAP Software machine?

Please suggest.

I have been using Symantec AV on my portal boxes. HP/Windows

With any AV software you are going to see a performance hit.

I have the AV software not doing an active scan on DB files.

Hi Vinod,

1) An antivirus is a must for any system so no matter what you install you should have a antivirus.Hence its highly advisable to install an antivirus that contains SAP software.

2)Ya surely there will be an impact when you running an antivirus with the SAP software if this is your issue you need to increase your RAM size and maybe even your virtual memory settings too.

3)Ya surely you can include the list of directories and files in your antivirus scanner which will not be scanned.You can check out this link http://www-tus.csx.cam.ac.uk/virus/VSE80config.html for mcafee on how to do it.

4)SAP does not recommend any specific antivirus any good antivirus like mcafee,norton kaspersky will do good.i would recommend kaspersky since its light on memory and best in class.
