I been having nothing but problems with ccsvchst going out of control and spiking up to 100% of my cpu for quite a while.
It is and was definatly due to Norton AntiSpam.
I'm using XP and Outlook Express.
It started with NIS 2012 and I upgraded to 2013 a while back to see if it would help the problem but it didn't.
(I won't use 2014 because I don't like the new style identity safe).
I was getting spikes to 100% every 3 minutes 24 hours a day even if my system was idle and not being used or if outlook express was open or closed. I always figured it was checking for live updates and never considered it had anything to do with OE because that is set to check for mail every 2 minutes and I would turn it off when trying to reduce the ccsvchst usage for other things.
I also had a terrible problem with anything using flash. Websites or you tube videos would clow the system to a crawl with ccsvchst always pegged close to 100%.
It even got to the point that when I had to use you-tube (I have been watching some instructional videos, I had to install a version of portable Firefox onto a partition that was excluded from Norton, then I would enable quite mode, and disable autoprotect and the firewall, and automatic updates and ccsvchost would still spike up to 100% every 3 minutes and sometimes stay there for several minutes at a time.
Since my first post about 7 hours ago, I have got ccsvchst under control by turning off Norton Anti-spam, rebooting and re-enabling it. (I may have had to go through that process twice).
Now when I have Norton Antispam enabled and OE open I onlly get 50% spikes every 3 minutes.
Curiously they all read almost exactly 50%. The big difference now is that when I close OE I no longer get the spikes every 3 minutes. All day today doing normal work I have only had 3 times that ccsvchst hit 100%.
It still spikes up for flash content and you tube but nothing like it was before but I still get annoying pauses with OE open in the background while I'm trying to do y normal work.
When I disable Norton Antispam the ccsvchst drops to almost nothing and I experiance no pauses, delays or hangs.
Thanks Steve, you helped my reduce the problem by half while still using antispam, but I think I also need to turn it off for good.
