Windows 7: SVCHOST Network Service taking up 30-40% of CPU

SVCHOST Network Service taking up 30-40% of CPU

Hello,

Seemingly out of no where (this computer is a couple years old) my internet on my PC would just stop working (started about two weeks ago). Malware searches and virus scans turn up nothing. Noticed that SVCHOST.exe was taking up about 30-40% of my CPU under network service username (if that helps). I did some googling and found some info regarding superfetch and turning it off, so I did and that did nothing to help the problem (that I can tell).

I also ran RogueKiller X64 since the issue and cleaned three registry issues...


Any suggestions would be appreciated
Thanks!!

Not sure if this will help at all, but the services that seem to be associated with the spike in cpu usage are CryptSvc, Dnscache, Lanmarworkstation, and NlaSvc.

Ending the process doesn't seem to cause any issues, except making my internet work like normal until the processes restart.

Are you using Firefox? I found this solution worked for one:

I also have had an issue with svchost.exe causing 100% CPU usage. The services in question related to svchost are NLASvc, LanmanWorkstation, Dnscache, and CryptSvc. My problem ended up being Firefox. In the latest version they added plugin-container.exe which runs as a process separately from Firefox. The idea behind it is if a plugin crashes it won't crash Firefox or your browsing session. But it made surfing on my system unbearable.


The solution: Disable plugin container process.


Open Firefox web browser.
Type about:config in the address bar and press Enter key.
A warning will appear. Ignore it and press the “I’ll be careful, I promise!” button.
In the Filter field type dom.ipc. Six preferences will appear for the filter dom.ipc.
Ignore first and last preferences (dom.ipc.plugins.enabled and dom.ipc.plugins.timeoutSecs). Toggle (double-click) each of the four remaining preferences to change the value from “true” to “false“.
You are done, restart Firefox and open up Windows task manager to see that the plugin container process is disabled..

Thanks for this

I use Chrome, though I think I use to use firefox on this machine... it's a couple years old, and I just can't remember. I checked services for the plugin container and didn't see it. I ran a searched and found plugin-container.exe.cfg, and firefox.exe.cfg that is all that I could find with the plugin-container (tried searching some variations in case) , so I deleted them to see what it would do, and there are no changes to my machine, and I still get the slow down.
