On Windows, I can use ProcessExploror + TotalVirus to check every single running app's exe, dll Signatures against 60+ virus scanner's databases.

It is not perfect but give me a lot of comfort about all the running app, .dll files in my system. It helped me easily detect my kid's game machines of some internet drive by download issues before and work very well to remove those apps/files.
I really wish Google can create something similar for Android. Love to see something similar for iOS, OSX also.
