ccsvchst.exe randomly uses 15-25% CPU?

Hi guys,

I'm seeing a very strange issue. As mentioned, ccsvchst.exe will often (sometimes more than 50% of the time I spend doing everyday work) run at 15-25% CPU. To the best of my knowledge, I don't believe Norton is scanning or even checking for updates, but it still uses 15-25%. 

I have a quad core processor (Core i5-3570k), and this would lead me to believe it's using 100% of one core. Is there any apparent reason why this may be happening?

Welcome,

I don't think your assessment of the 25% = 100% of one core is accurate. I'm not positive that the program is monitoring more than a single core. The percentages aren't out of line for quick scans when pulse updates arrive. They can be pushed out as often as every ten minutes.

My system is only a dual core and the percentages are about the same.

Re: ccsvchst.exe randomly uses 15-25% CPU?

I routinely monitor temperatures, voltages, and % load of my CPU, and when ccsvchst is at ~20% it's using >80% of one core. When these scans/updates are running, (which happens at least once an hour) the temperature of my CPU jumps 8-10 degrees, and my power consumption jumps 10 Watts. This might not seem like much, but it's enough to annoy me at the least.

If this is normal, is there any way I can perhaps decrease the frequency at which these scans/updates occur? I don't see the need to update definitions more than once a day, and the same goes with quick scans.

You could turn off Pulse Updates at the risk of getting a Zero Day infection. If your surfing habits are not questionable this may not be an issue for you.

Go to Settings - Computer- Updates and turn off the setting for Pulse Updates.

See if this helps.

In addition to what Peter has suggested, I can give you further info,

Unfortunately, this is not intended by design, quick scans are performed automatically whenever the database virus definitions is updated, regardless of whether Smart Definitions are set to On or Off.

Since the virus definitions are updated (on average 2 or 3 times a day), quick scans will be performed with the same frequency that normally runs while the computer is inactive.

The only thing you can do is to edit the timeout inactivity, which by default is set to 10 minutes and may be delayed up to 30 minutes, this could reduce the number of quick scan when you aren't 'using your computer.

To change these settings, go to: settings / General / Idle Timeout "or something like this, since my GUI is Italian," I don't know as it's written for the English UI.

I hope this can help you.
