Was wondering why I haven't been running ESET AV on my Win 8.1 (forgot lol) so I installed it once again. Everything works fine till I reboot then I discover I no longer have Aero and I have a black bar from the right edge going roughly 1/8th way in from bottom to top that is on top of everything I load.
I uninstall ESET and all is fine again.
I would really like to know why this is happening, any help appreciated
