    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.

          IaM ALSO HAVEING the same problem,i accidently posted in the 2009 internet security. Mine goes from 0% to 100% cpu useage from bootup( bouncing between that cpu useage amount)'unless' i kill that sevice!Problem started same time as you mentioned! I have a socket 939 AMD dual core cpu and video playback is erratic as well as playing games! Im useing a Gigabyte K8ns-ultra MB 2gb memory OCZ brand,XP Home with SP3 installed! I am useing a Nvidia 7950 GT VIDEO CARD WITH 512 MB ofonboard memory!

            I also hope a 'resolution' is found to this problem,i am visually disabled and my computer is very important to my world.

            Any idea what the heck this service is for? Since i can 'end process' through task manager( takes 3 times to make sure it doesnt pop back up) and as far as i have seen all the normal services are running normally,scanners,firewall,real time scanning, not sure about'updates' though. Says that'all is ok' in the main screen.

            I had the same problem when I downloaded the 2010 version from austrailia McAfee site. My cpu was running around 50% or higher on this process so I redownloaded 2009 version from United States site. Why does that process make my computer kick into high fan speed? Seems McAfee is making alot of problems for us home users. Hope they correct this issue before putting 2010 version on US site,

              Doesn't anybody know what this exe is for? It is not anywhere in task manager in processes running in McAfee Total Protection 2009 but is in the 2010 version. This needs to be checked out by McAfee why this process uses so much CPU. Really seems newer products from McAfee are getting worse each new version released.. I am running windows XP Home edition sp 3 with latest updates installed.

                I've found out that this is a problem carried on by the beta version. There's a ton of links for beta-tester opinions on the internet, almost all of them saying that McSvHost is a resource hog and hopefully it's going to be fixed in the final version. There was even a post from as far back as August 2009 saying that. Obviously, they didn't fix it. But my concern is, why did the program work (almost) flawlessly until the Jan. 19 update? They re-messed it up afterwards? Oh, and while I'm at it, do something about the full-scan speed. I mean the previous version scanned my PC in about 90 minutes. Now it takes up to 3 hours. At least it seems the scan is much more thorough. I mean, tracking cookies? And McAfee detects them? C'mon...

                  Well i guess then the'download from website' is the currupted version then? I used the 2010 install disk to 'reinstall' McAfee and it goofed up the online AFTER the online update! Took my pc half a day to complete a scan of 2 80 GB hardrives! Ill agree it BEYOND FUBAR FOR THIS  kind of service. No reply's from mcafee yet on this thread,what kind of support are they thinking? Seems strange they KNEW about this'flaw' back in 2009 and basically DID NOTHING to correct it????  Seems quite strange indeeed

                   

                  WE NEED A FIX MCAFEE NOT AN EXCUSE!

                    I cant afford a new prgram from another manufacturer or company,i paid for a working 'correctly' program,not a half baked update that screws things up!

                    Seems like McAfee updated again today. Everything except the Firewall was updated. I'll wait a few hours with my PC turned on (and my fingers crossed) and hope the glitch has been fixed. Otherwise, you'll hear from me again soon.

                     

                    Side note and completely off-topic: I received an email from this site with a link for a password reset request I apparently made a couple of hours ago. I have made no such request and of course ignored the message. Just curious...

                      Hi mcafee123,

                      May I know whether the computer had any recent changes like a hardrive reformat or a system restore, or any malware infection in the past ?

                      Also try to run a full scan with mcafee and check whether it detects any Potentially unwanted programs.

                       

                       

                       

                       

                       

                       

                       

                      Regards,

                      Dinesh K

                        Hey Dinz

                         

                        This version of McAfee was installed on a clean-installed version of WinXP SP3. I had just changed the HDD on my PC and performed a clean install of everything. That was last December. The problem started just after the January 19th upgrade. No viruses or PUPs found so far, just some tracking cookies, which have been deleted. After yesterday's McAfee upgrade, I haven't encountered any of the past problems, but it's too early to tell; it may take up to 7-8 hours for the McSvHost process to start acting up. I'll also gather feedback from a friend of mine who experiences the same problem and get back to you.

                          Interestingly i guess im not worthy of a responce?

                            Doesnt matter i guess as so far the'new updated' McSvHost.exe' ISNT causing the cpu to go'bonkers'. Ihave been monitoring that part of the day! So thankfully it 'might' be fixed on my machine. So thanks for a'reply' at least to someone on this issue.
