Big Problem -trying to get rid of it for 7 days

Has anything changed since we started cleaning?

I went on to regular start up and it seemed a bit better but would not let me run any antivirus.
The disk is showing 100% usage  (it has 300 gigs free) and I read that AVG can do that - so have tried to take it off and 6 dll's are saying they are being used by another program and won't delete.
It still won't let me do any kind of refresh. Its still quite bad

I don't have time to work on it the next few days, so lets just leave it as I may just send it out to get Windows 8 reloaded.

I'll come back in a few days if I need more help.. THanks

Windows 8 and 8.1 comes with its own AV called Windows Defender. You would be well advised to uninstall AVG. If you have problems, you can use the AVG removal tool below.
