Avast being intrusive

[Psychospacecow]

I turned on my computer today only to find that Avast had installed its own browser called safezone and a stupid price suggesting module called safeprice. I'm considering dumping avast in favor of an anti-virus that doesn't act like malware, but before I do that, I was wondering if anyone else has dealt with this in the past and if so, how to get that off my computer w/o removing avast as a whole.
