LW 4.2 has no adaware! I don't know what crappy adaware app you're using but I'm aware that at least one on the market hasn't been updated for some time & finds adaware/spyware where there isn't any just to make you think it's doing a good job. But all it does is create an illusion & do damage to your apps.
