OK i just turned on my computer and got a pop up about a new version of Avast for download, so i installed it. I then had to restart my computer, when it came up it would not load avast. I try to run it manually and it says
Avast cannot load library from file: C:/ Program files/Alwil software/Avast4/aavm4h.dl
