My computer is running very slow for the last few months.  I bought hitman pro on the advice of a friend and I have run free version of malware bytes, all without any change.

 

When I look at my CPU usage it is pegged between 90 and 100 percent most of the time.

 

Can anyone help or steer me to a program that may help?

Can you identify which processes are using the most CPU? Just look at Task Manager.

Chances are you're infected with malware.

Please create a new topic in here. The staff will be able to provide more assistance than I can.

Read this before posting.

I wish you luck.

NOTE:  It's not necessary to create a new topic, I moved topic to AII forum.

 

In the future...please just use the REPORT button for any topic which may require moving to another BC forum/subforum.

 

Thanks :).

If the scanner detects a powelik detection, it will notify you. Press Y to remove it - it should then say the following: Win32/Poweliks was successfully removed from your system. Press any key and reboot your system. A log will be created on the desktop, please paste the contents of it into your next reply.
 
Alternatively, if it doesn't detect a powelik, please let me know!
