Computer does not run any avg programme

I followed microsoft link exactly both auto and manually. No luck. More strange things!! I downloaded the WIN 8.1 upgrade assistant EXE file would not work. Downloaded something innocent VLC video player EXE file. Worked fine. Something a bit different about the WIN update It flashed the blue 8.1 logo then just nothing. When I tried running it again got a window message saying "Windows setup aleady running". At the moment just giving you all the info I can. I am truly thankful for all the suggestions you make. So at the moment I cant get AVG running or remove or renew it. I cant load another virus or malware programme or find out if I can update Windows but I can install a new viseo player.

Hello John. Thank you for the information. I would request you to follow the steps in this Microsoft support article https://support.microsoft.com/en-us/kb/2688326 . Please do not forget to take a backup of your registry ( https://support.microsoft.com/en-us/kb/322756 ) before you make any changes to your PC.

All fixed I hope. Found out by searching the web that this is a big problem at the moment. A series of malware intend on stopping any attacks. The advice was use Windows Defender Offline. Downloaded it and it prepared a bootable DVD with the malware killer. ran a quick check then booted the computer again and AVG was up and running. Since, no problems.
Thanks for all your time and effort.
