Windows Defender

HI

 

When istalling VirusScan 8.8 there is a mesage that pops up on Windows Vista and Windows 7 machines advising to disable Microsoft Defender

 

Has anyone carried on without disabling and what sort of issues have they come accross?

 

We are about to start allowing home users to connect to our network by VPN with their home machines.

They are forced to install VIrusScan before they can connect but they are geting the Defender msg.

 

If it causes no issues we would like to not ask them to disable or remove other security applications for obviouse reasons.


Thanks

Colin Edwards

    It automatically disables it, when VSE is disabled you'll see defender popping back up.

    Nothing to worry about.

    Re: Windows Defender

    I used ProcMon to capture Word starting up in our environment and the top three files sorted by file time are:

     

    1) C:\ProgramData\Microsoft\Windows Defender\Scans\mpcache-xxxxxxx.bin.VE0 - 7.6s

    2) Microsoft dll - 6.1s

    3) C:\Program Files\Common Files\McAfee\Engine\mferuntime-xxxxxxx.dat - 5.4s

     

    The fourth file is 3s and then it drops off with many resources accessed for under half a second.

     

    I believe the McAfee dat file is used so often on first launch because we have  "Processes on Enable" selected.  The dat file usage is not present for subsequent launches of Word.  However, since the windows defender service is still running and set to automatic startup I think I could get better performance by disabling the service, as we do have the McAfee anti-spyware module installed.  When I disable Windows Defender service that WD file no longer appears in my captures.

     

    Is there any McAfee documentation that covers Windows Defender?  Has anyone else disabled Windows Defender (GPO or script) when they saw this condition?

    Just one remark, if you manage the roll out via ePO there will be no popup for the end user it happens all silently. I don't think there is documentation on WD, it is disbaled on install and enabled upon uninstall, all good. You can try to invoke the setupvse.exe with /q, that should make the whole process silent again. Installation Guide has more switches if required :-).
