New member with problems here :thumbsup:
Have AVG working away plus Windows Defender
Recently had real problems staying connected to MSN messenger and often my CPU usage will shoot up to 100% for no apparent reason staying there and jamming up the pc
My son thinks it is something to do with some inf file or other but cant get rid of it as it just pops up again after deleting

Any help please ?

Your Firewall, AntiVirus, AntiSpyware or any running program will cause spikes while they are doing their thing.
If you keep an eye on the TaskManager, (Ctrl + Alt + Del), you will be able to see the constant changing of CPU Usage and what is using it.

Can you be more specific about what you think it may be.

The Svchost.exe process may spike the CPU usage to 100 percent during update detection or update installation. Also, the Svchost.exe process causes the computer to stop responding for various lengths of time...The Svchost.exe process produces an access violation during update detection or update installation...

Hotfix for issues that involve the Svchost.exe process

You can download and use Process Explorer to investigate all processes and gather additional information to identify and resolve problems. This tool will show the process CPU useage, a description, company name and its path (location). If you right-click on the file in question and select properties, you can gather additional information. Also see How to determine what services are running under a SVCHOST.EXE process and What is svchost.exe?.
