Guys, could you give a look at Windows Support community? There are a LOT of people complaining of a malfunctioning windows 8.1 update, me included. I just make a quick video. There are more details in the description

The thing is, I started asking some questions and turns out people were using Avast!

I managed to boot in Security Mode and just realized that avast has disappeared from the computer! Just a few reg files I could find with CCleaner.

I could definetly use some help here!
