Endpoint Protection freezing with Laptops
I am having a huge problem, and hopefully someone can share some insight.
We are using Symantec Endpoint Protection v 12. We have Dell Latitude E6420 Laptops and Dell Optiplex 990 Desktops. Both have Intel core i7 processors, 4 gb ram, Win7 32 bit. Obviously, the laptops have the mobile processor.
The problem is, when I install SEP on the laptops, their behavior changes. I will be unable to shut down the laptop, remove software, or perform active or full scans. When i try to do any of those, Windows freezes indefinitely. The system also becomes slower (at logon especially)
I have narrowed this issue down to the Antivirus portion of the SEP install. If I uninstall that part, and leave Proactive Threat Protection and Network Threat Protection installed, the system operates normally. Speed is increased, I can shutdown again, and I can install/remove software.
This does not happen at all on our desktops, which are built the same as our laptops.
I first noticed this issue when we were using SEP 11.7, and thought upgrading to 12 would fix it. The problem still persists.
I have looked at every log file I can, and even submitted files to Symantec with no solution. People don't believe me until they watch me uninstall the Antivirus portion and everything starts working again. Unfortunately, we can't deploy the equipment without antivirus protection!
My thoughts are this is an Auto-protect or Kernel issue, but I don't know. Anybody's insight would be wonderful, as I have been working with this for months with no solution!
