As for So Blonde - a lot of people had to un-install AVG to make it work.
There's no trojan virus or anything other bad in the game.
Also you might want to update AVG AFTER the install and play of So Blonde
As for Vampyre Story - you may have to do other things before you can move the pillow.
If not, then moving it is a bit tricky - your hand has to be a bit off the pillow (maybe lower) to move it.
