My computer has been freequently getting very slow and freezing up for several minutes at a time as I try to watch video, such as the Daily Show. It will then run for about 30 seconds and then freeze again.
I checked the Task Manager, and McSvHost.exe was almost always using a lot of resources and really racking up the page faults. So I tried disabling various parts of McAfee and found that if I disabled the Firewall, then the video would start running normally. So I assume that something about the Firewall is using some limited resource. It can take a while to turn off the firewall since the computer is quit slow on most thngs, not just video.
I have always felt that McAfee was slowing down my comuter but this extreme problem is relatively new and may be related to a recent update.
Any suggestions would be appreciated.
This fix is in a patch that was to be released today but they found a bug in it. The offending feature is netguard so disabling it ( a firewall feature) should allow normal use of the pc till the patch is released. Many have done this and got a workaround. Ok the firewall loses a feature but as long as you have Siteadvisor active things should not be a worry.
The old 2010 firewall never had this feature and it was safe.
Thanks for your suggestion. I have turned off my netguard. I will periodically turn it on to see if problem has been patched.
The builds you need are
McAfee Security Center
Firewall was also updated with that update - 12.0.355
The McAfee updates arrived here in the UK about 6 hours ago. If I remember the release schedule correctly the US and Canada will get them in a day or two.
They actually started there and in Uk last Tuesday just they were throttled so only a small % users got it each update check.
So is everything Ok now re mcsvhost if you had it that is? I assume the net issue is still there?Message was edited by: Peacekeeper on 10/06/12 4:04:24 PM
