100% CPU usage for no apparent reason...

I was referred here from the Malware forum after user Gammo was very helpful in disinfecting my computer. I have a Dell Inspiron 1420 running Windows 7 Ultimate. I only have 2GB of ram.

I am having a problem where the CPU usage suddenly goes to 100% for no apparent reason when I am running only Firefox and perhaps AIM, with my antivirus (AVG) running in the background. This, of course, makes it impossible to use the computer. It was happening constantly before, but now that the computer has been disinfected, it is still happening occasionally and for short periods of time, but sometimes longer. Sometimes I have to resort to restarting to be able to use my computer.

I would greatly appreciate any help, thanks!

Here is the link to the post in the Malware forum.

After you decide what antivirus you want to use it is safe for you to disable all of your startup entries except your antivirus.

Hit the start button in lower left hand corner. Then in the run box type msconfig, then hit the services tab then put a check mark in hide microsoft services what is listed there,after hiding microsoft services?Please post back to us in a vertical list.

Or just post a screen shot of the services running after hiding microsoft services. :)

Hit start button at lower left hand corner of the screen.Then in the run box type services.msc. Find the service listed below,one at a time. left click it once you should have the option to either stop the service or restart it , stop the service then right click selected service select properties then change the startup type to manual then left click apply and move on to the next service.If the service is stopped and the startup type is manual then do nothing.

Do the above for everything except anything to do with avg.Only with the services you posted in your last reply.

Also leave the sigmatel audio service alone,then rerun tfc.exe and reboot.

Also I would uninstall avg and run the avg removal tool and then install avast if it were my machine.

uncheck everything in the start tab (using msconfig) except your alps pointing device and whatever AV you kept...
I use and recommend MSE at this time...its run using minimal resources...
whatever you chose as your AV...update and run it...
report back if it finds anything
