Since Norton is taking up 98% CPU time, I need it disabled for a customer. I don't want to uninstall it since they have a 2 year subscription (Don't worry, I'll smack them later), but I want to disable it from starting up. When I go through MSCONFIG and remove the service, I get Access Denied. When I go to SERVICES.MSC and disable it, I get Access Denied. Same effects if I start in Safe Mode. So how can I disable Norton without uninstalling it, in case the customer wants to use it?

PS - The issue is that his computer is extremely slow after starting up. No viruses detected, RAM is good, and HDD has no bad blocks. In Task Manager, I see the 98% CPU Time for the ccApp process.

From the Norton forums:

If you want to manually shut down Norton 360 completely, you may need to get into Settings of Norton 360 and disable each protection individually.

  1. Under Quick Controls, uncheck Identity Safe and Phishing Protection.

  2. Click Virus & Spyware Protection. Under Automatic Protection Settings tab, uncheck Turn on Auto-Protect, Turn on SONAR, Turn on Suspecious Activity Monitoring, and Turn on Email check.

  3. Click Firewall Protection. Under General Settings tab, uncheck Turn on Firewall and Turn on Browser Protection. Under Intrusion Prevntion tab, uncheck Turn on Intrusion Prevention.

  4. If you have Add-on pack installed, click Norton Add-on pack in Settings. Uncheck Privacy Control, Parental Control and AntiSpam. Click Done.

It's dated 2009, so things may be a little different in your version, but I think the gist is there - disable each service individually.

Tell them the only way to stop all bits and pieces from loading is to uninstall it. They can always reinstall it later if they want. :)

I will try this tomorrow at work, and upvote and mark if it works for my version. Thanks – Canadian Luke Oct 27 '11 at 3:15
It jumped from 99-98% down to 95% by disabling every last detail... I'll uninstall it, and let them know that was their slowdown. I wish Norton would let you actually control it a bit better though – Canadian Luke Oct 27 '11 at 16:36
Uninstalled. Customer says they're gonna try for a refund – Canadian Luke Oct 28 '11 at 15:28
