I use AdBlock, is that considered safe?

Currently, yes. But who knows what someone will find next week.

This Adware Doctor was most likely perfectly clean when it cleared Apple's stringent curation to get in the Mac App Store, but they probably altered it after it was allowed in. That will get the publisher a lifetime ban for ever getting any other app sold through Apple's stores. That kind of bad behavior has consequences.
