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).

Notes:

  • Symantec Endpoint provided by company.
  • Others in company are not experiencing the problem.

That's Symantec for you!

I hope you get an answer able to actually fix/address this individual issue, but, I doubt it.

Generally speaking, the business tools are better, but, I have seen nothing but problems with Symantec products of recent years and with the exception of Backup Exec, I do not sell any of their products any more.

This is the sort of problem I used to see all the time when supporting it and the only solution I can really suggest is to swap vendors and try another anti virus solution.

You may hate it now, but, it will be for the best in the long run.
