welcome to the forum.

i suggest you try to repair avast as a first option.

go start/ controlpanel/ add/remove programs, scroll down to avast and hit the remove button.

a new screen should come up, from there hit the repair option.

if this should not work.

try a installation from scratch.

good luck   
Windows 8.1 amd a10-5700 64 bit

I can not download anything as not browsing works.

Try this :  Start Menu > Command (run as admin) > type in SFC /SCANNOW and run that which should deal with the corrupted files.

As AdrianH posted above please run the SFC repair, Start Menu > accessories > Command Prompt - right click (run as admin) > type or copy in  SFC /SCANNOW  and click enter, this should fix your problem.

Are you able to get to safe mode ? if so then open up computer and right click on C drive\properties\tools check drive for errors and tick both boxes then click start and you will then be asked to reboot, try that and let us know how it goes.

Safe mode does not work. No repair option. And system recoveries does not work.

I would normally refer this to essexboy now but he's away till the 6th of october so hopefully someone with a bit more knowledge can shed some light on this for you.
