AAAAAAAARRRGGGHHH

Computer gone weird again.

It was behaving a bit oddly - some tabs I had open in Firefox were hanging when I was trying to refresh them - so I thought I would restart -

- and as bloody Avast had been nagging me to update by restarting I clicked on that (Avast has been being a pain with popping up on top of things and trying to get me to upgrade and so on)

- and here am I in that situation I had before where computer will not start properly.

Did try system restore and allegedly there is no restore point WOT.

Does get so far as to claim it is updating and then hangs around 35% and eventually comes up with oops error, here are your options. I have tried most of the Troubleshoot suggestions short of actual Reset but that may be the next thing.

AAAAARRRGGGHHH.
