Please don't be that starry-eyed. This checks do what they can, but they are far from perfect (very far).
A software that would do good checks would be a huge amount of work and still a race between the devs of this software and the idiots who write brickers.
@Vitaminer 'Always read comments and things from people' is a good advice. Also you shouldn't install stuff from untrusted sources.
You wouldn't do it with software on your computer e.g. on windows.
The big diffrence is that you can't just delete the whole OS and set up a new one here since the system is very closed and inaccessible in may ways (also the programmer of brickers still tend to be not very skilled atm. Let us hope that just bored kiddies without proper understanding of the system continue this work).
Stay wary and thoughtful then it will be good
(And don't install vpk's from random internet sites. Also if a software wants special permissions only install it if you know
why it wants them.)
