I am having problems on my Laptop with Symantec, its a very strange problem -
Interface lags, and mouse is jerky at almost random time intervals. I did a bit of digging and it seems that no matter what program I'm currently working in - Firefox, Outlook etc... it says its using massive amounts of CPU - 60 -> 70% and smc.exe, WmiprvSE.exe and svchost.exe are up near the top too.
A bit more digging found that the service running in the svchost.exe process was netsvcs.
Using process monitor I looked at what smc.exe was doing and found that its making massive amounts of registry calls. 174,000 in 2 minutes - compared to 20,000 on another machine with very similar set up.
The keys its accessing are the TCPIP settings (i think...) of the network interfaces : HKLM\System\CurrentControlSet\services\Tcpip\Parameters\Interfaces
Some of the keys its trying to access don't exist. If i copy large amounts of network data then my computer slows dramatically. I have reinstalled Symantec twice, removed unused network connections in windows, uninstalled winpcap, tried a reg clean and also tried resetting the TCP/IP stack in windows. I have to concede a loss on this one.... Any ideas what is causing the performance issues, and what I can do to fix (without a rebuild).
- Symantec Endpoint provided by company.
- Others in company are not experiencing the problem.
