Firewall freezes up my computer

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.

Re: Firewall freezes up my computer

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.

Re: Firewall freezes up my computer

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.

Re: Firewall freezes up my computer

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?
