Hi,
Windows 7 64-bit with the latest update.
Symantec Endpooint Protection 12.1.2015
Windows Firewall is turned on and block outgoing connection by default. Live Update has been enabled through Firewall so that the software and virus/threat definition is kept up to date.
In the last month of so, I've seen degrading performance of my PC. Many examples.
Starting a program now takes a few seconds.
Open an email attachment in Outlook take 10 or more seconds
Clicking on a link in Outlook takes 30 seconds or more to open the page in browser
I kept task manager on the side then I noticed as soon as I click on the attachment or link, ccSvcHst will take 100% of a single core. Until that goes away, no file or link will be opened.
What could be causing this?
Thanks
