Hi people,

For the past few weeks every couple of days for about half an hour or so my computer goes nuts on the CPU usage and when i check the processes that are running there are mainly two which are going mad. The image names of them are McNASvc.exe and svchost.exe. Ive done a definition search and ive been advised not to touch McNASvc.exe as it is to do with my virus protection (mcafee), however, i believe the svchost.exe can be a virus using this name to fool the user. On checking all the processes on the task manager i have the image name svchost.exe repeated 7 times!! sureley this can't be right?? the user name for each image name is either SYSTEM (4 times). LOCAL SERVICE (1 time) or NETWORK SERVICE (2 times). The mem usage for all of them is roughly the same, between 3500K - 7000K but there is one which is using 29508K which is the process making the CPU usage run high. Ive ran the mcafee virus scan many times but nothing is detected etc etc. Can anyone please help, this is doing my head in!!!

Thanks, Rob.

Hey there mate, take a look at this thread and see if it is relevent to you, I am going to assume this is similar to your problem.

'svchost.exe' is not a problem as it is part of the windows operating system, all it does is run dlls(basically) if there are any spelt differently then it could be an issue.

If this fails to fix the issue please run through the PreWork and post back for the security guys to take a look at! thanks.

hope thats it, gonna try that solution to the windows update problems but there are quite a few downloads to choose from and i haven't got a clue which one to use. The system im on is windows XP, home edition, version 2002, service pack 2. Which resolution download and which windows update agent should i use? ( not to sure what x86.exe or x64.exe etc are)
thanks, rob
