McSvHost.exe causes error on Shutdown

I am getting this error also during shutdown. It's an "application error" saying "memory could not be written". I just installed Mcafee a couple days ago, it's the newest version. Doesn't seem like it happens every time, except lately it seems to.

Here's my about info:

McSvHost.exe causes cpu spike, lagging, and buzzing - very annoying

So I just recently started noticing this performance issue first during gaming, but now while listening to itunes are even surfing the internet. I havn't yet seen it while completly idle though.

The computer lags horribly and any audio being played turns into a buzzing noise

this video gives you an idea of what i'm talking about. check 2:20 ish.

I run a windows 7 64bit

intel i7 2600 processor

8 GB ram

and a radeon 6900 graphics card.

also the computer was bought from Dell: XPS 8300, if that helps

What i did was run windows resource monitor while i was listening to music and surfing the web and managed to find out that it was McSvHost.exe that was causing these spikes; which spiked to 100 percent then back down to normal in roughly a third of a second. I'm guessing cpu usage at 100 percent is probably causing the lagging and buzzing. Not sure if its recomended to delete McSvHost.exe permanently. i'm hoping that an update of somesort will fix it.

I hope that someone can give me a solution. My computer is almost brand new and i can't get full enjoyment out of it.

Thank you.

McSvHost.exe cripples my PC

I'm running the latest version of Mcafee Security Center. After the January 19, 2010 update, the process  McSvHost.exe (which is actually a McAfee process) randomly fluctuates from up to 50% of my processor time to 0%. Once this happens (usually after a few hours of the PC being booted up), it cannot be stopped unless I temporarily disable my wireless network adapter. Apart from it being annoying, it also has a very real impact on my PC's video rendering capabilities, causing uncontrollable stutter in video playback, gaming and every other graphics-intensive process.

A friend of mine has the same problem, only in his case, the McSvHost.exe process starts taking up 50% of CPU immediately after boot-up. Both PCs run WinXP SP3 Professional, with 3GB Ram and fairly new (less than two years) CPUs and even newer GPUs.

I hope this is resolved ASAP, as I am really disappointed that it's been now almost two weeks this has been happening and I am tempted to switch to another security program, that doesn't actually crash my computer.
