I have a Toshiba laptop running Windows 10.  I downloaded Avast Free as that is what I've always used and trusted.  I just turned the laptop on and when I look at Task Manager it shows Avast Service (32 bit) is using 99% of the CPU.  I turned the laptop on at 7pm and it is now 7:45pm and that percentage varies only between 96 and 99%.  This is a 64 bit pc but I could not find a 64bit version of Avast.

I started to uninstall it and it asked if I wanted to repair it so I chose that option.  It finished running and said it completed.  The laptop rebooted but it is still using 99% of the CPU. 

I should mention that right now that laptop is not connected to the internet.  I don't know if that would make a difference or not.  I would think it should not as my old 64-bit Windows 7 laptop is running the same software and is not having any problems whether it is connected to the internet or not. 

I guess I'll uninstall Avast until I get a solution here.  Does anyone have any ideas?
