I use windows 7. My CPU usage stays at 100 percent. For example when I am using Google Chrome it goes up to 100 percent.

I have already used many programs such as tdss killer, ccleaner, malwarebytes, adware cleaner, malwarebytes anti-rootkit

but none of them detected any malware although ccleaner did remove a lot of temporary files.

Please help.

What steps have you taken to identify the Process that is consuming this high CPU ?

Try opening task manager / processes / all user processes / Click the CPU Tab at top to bring culprits to the Top and observe which ?

It also maybe Windows Updates trying to update , if so there are various Threads on that issue also.

When the computer is idle it fluctuates between 10-20%. The main process during this time is system idle.

When I use an application such as chrome it immediately goes up to 100 percent and slows down the computer. The main process this time is Chrome ,taskhost.exe, system idle.

 

I have windows update disabled.

- (Temporarily) Remove all Chrome additions/plug-ins.

- There could be a corruption of files. Run the command "SFC /scannow" in the MSDOS windows (with admin rights).

I disabled all plug-ins but it made no real difference.

 

I ran the scan through ms dos but it said 'windows resource protection did not find any integrity violations'.

- What software did you install recently ?

- Re-boot in Safe Mode. What is CPU now ?

- Do a "Clean Boot". What happens now to CPU ?
