My computer seems to be running slower and slower. It's windows 8.1.
I've scanned it with superantispyware, malwarebytes, adwcleaner, JRT, CCleaner, TFC and Avast free. Avast says I have grime on it.
The browsers (firefox and chrome) both are slow. And in typing emails, the text types slow. I have to wait for it to catch up at times.
Can someone please help me?
