Windows 8 freezing at screen save and not booting up

On the flash drive should be a text file called FRST.txt.

Use the attachments and other options option under the answer box to attach it.

OK McAfee is installed and running on this computer and it blocked Avast all bar one driver. 

I will remove the Avast files leaving just the Licence file and the setup file
It should boot normally after this
But, before you install Avast again you must uninstall McAfee, I will assist if you wish

Download the attached fixlist.txt to the same USB as FRST
Run FRST as before and press Fix
On completion reboot to normal windows

OK Avast was not the cause then ..  On the advanced options of the recovery console could you try a system restore to a point prior to the non booting
