What the 'like' button does is annoy the Hell out of me after paying for AIS and evanglising it with everyone I know. I dislike the moronic facebookisation of the world and am disappointed to see the avast! people being suckered in like sheep.
I dislike it so much, in fact, I uninstalled V6 and put V5 back in where it will stay until the avast! crew yank the damn thing or have it hidden by default.
If they decide not to, I am sad to say will be shopping for another application to do the job.
