I just read about this application in the August 2015 issue of Maximum PC. Turns out it has been discussed on Wilders Security before, for example here, but that was three years ago. Apparently nothing much since then. Does anybody here use Heimdal, and/or know how useful or effective it is? Reading their website doesn't give me great understanding of what exactly it does, how it works, or what security function it's intended to serve. How does it compare to, say, HitmanPro.Alert? Would one run it alongside HMP.A or instead of it? Any insights are welcome.
