It has certainly had that effect on me. When I heard that notepad++ was being flagged for something somewhere by someone, all I thought was "so they forgot to pay a protection fee?" Genuinely I thought it was being brought it up just as an indication that the developer may be absent or asleep at the wheel. There is literally no association in my brain between one of these warnings and the concept of software being compromised or not.

And I've seen other less tech inclined people click right through these without a moment's thought. They think it's just one of those things computers have to complain about.
