McSvHost.exe hogging CPU capacity

In past two weeks.  McSvHost.exe hogging constant 49-51% of CPU with mcshield.exe using 1 - 44% as read by task manager -"process" with NO applications open or running.  Any idea as to cause?   This is with or without real time scanning activated on McAfee.

Re: McSvHost.exe hogging CPU capacity

Moved from the Help section to main section, General Discussion.

Which one takes up the CPU, MCSvHost or McShield? Or is it both, as you imply, taking 49% and 41% respectively?

Re: McSvHost.exe hogging CPU capacity

Long threads on both



The mcsvhost seems to be caused mostly by the firewall netguard feature try disabling it , there ius a fix coming next patch release.

the mcshiled well that is harder is your PC a P4 with single core cpu?

Post the specs please.

I now have a test PC that Mcafee can work on it has this issue.

Re: McSvHost.exe hogging CPU capacity

I just downloaded the latest McAfee patch (4/28/12) and apparently that solved the problem with no other changes being made.   The CPU capacity devoted to McSvHost.exe has dropped from a continual 49 - 51% to 0-1%.

Were you getting popup error messages?  We were not told of any releases re fixes so will ask

Re: McSvHost.exe hogging CPU capacity

No pop up error messages were found regarding McAfee.   Is it possible that the restart after downloading the McAfee update could have reset the McSvHost.exe?

Re: McSvHost.exe hogging CPU capacity

This update was big so I hear but noone warned us. Some experiencing net connection issues. There was a mcsvhost fix coming but I expected it next month.
