My appologies if this has been answered before, but I couldn't find a solid answer using the search option.

Every five seconds or so my computer goes nuts. When I open up task manager, the following processes are taking up significant CPU usage. Sometimes it's only 30% of CPU, sometimes it's 100%:

SVCHOST.EXE
SERVICES.EXE
MpfSrv.exe
MCLOGSRV.EXE
Mcshield.exe
McNASvc.exe

I am running Windows XP Service Pack 2; let me know what other information you need to know. ANY help would be much appreciated!

Posted Image. The first two COULD be part of the operating system. The last 4 are part of the McAfee security software. When these go up to 100% what are you doing? Are you using P2P programs? What kind of other security software do you have running ?

svchost.exe is a generic host process name for a group of services that are run from dynamic-link libraries (DLLs). This is a valid system process that belongs to the Windows Operating System which handles processes executed from DLLs. It runs from the registry key, HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Svchost where details of the services running under each instance of svchost.exe can be found. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. It is not unusual for multiple instances of Svchost.exe running at the same time in Task manager in order to optimise the running of the various services. Determining whether svchost.exe is malware or a legitimate Windows process depends on the location (path) it is running from. The legit svchost.exe file is located in the C:\Windows\System32 folder.

services.exe is the Services Control Manager process which interacts with and manages the operation of starting and stopping system services that are run as processes, as opposed to those run in svchost.exe. It also deals with the automatic starting of services during the computers boot-up and the stopping of services during shut-down. Determining whether services.exe is malware or a legitimate Windows process depends on the location (path) it is running from. The legit services.exe file is located in the C:\Windows\System32 folder.

Yeah I know what each of the processes do or what they're associated with, but their activity on my comp is quite suspicious. Yes actually I forgot to mention that in my first post but the problem occurs the most frequent and most drastic when I'm running, or immediately after running, a P2P program. The problem tends to calm down after not running the P2P program for awhile. I'm not running any other security software
