Avast will not restart!

Have paid for this Avast but every time computer updates ( Windows Vista ) always turns Avast off but this time I cannot restart! Please help and be specific as i am not a computer genius! not lol ing!!!

Please, upload (attach) the avast log: C:\Program Files\Alwil Software\Avast5\Setup\setup.log

If the file is too big for the forum, post the last 400-500 lines of it.

You can open it in Notepad, even it is “locked” by avast.
