Slow..slow computer

Hi,

My computer is running very slow. I tried deleting files cause I thought by deleting them, my computer would be running normally but it didn't.I looked at the Windows Task Manager and search every single processes that my computer is running and I found out that 'Isass.exe' is harm and should be deleted.I can't delete that process so could you please help me..and also look into other problems of my computer. Thanks in advance.

Here is my HJT Log:
