My laptop Toshiba Satellite A100 has a CPU usage of (near) 100% continuously.
I have been trying to determine which process could be responsible, without success. I also switched off the network connections, also without result.
How can I find out the reason for this load and correct the situation ?
Thanks, I will try that.
I've not found out yet how to copy the picture of the task manager.
Meanwhile, I let AVG run a rootkit scan and it found 3 infections, which have been quarantined. After reboot the the situation remained as before (100% cpu usage), but all of sudden that dropped to a normal 0 - 7 % ! It has remained there since.
Could it be the rootkits claiming all that cpu resource ? I did not notice any extra network traffic during this all.
It appears now that the problem was not with the rootkits. Process Monitor revealed that a service belonging to a driver program to connect my mobile phone to the laptop, named Moto Helper service was using up nearly 100 % CPU time. The service could not be stopped by Task Manager so I uninstalled the driver. Everything points to a corruption of the hard disk, since removing the program I discovered that the sound drivers are now unable to load.
