Tor network (Orbot for android.)

Hello there, I just joined this forum, in search of answers to further my knowledge of the tor network. I recently found a file archive on the deep web that had various files, and I managed to find the latest version of Orbot for android, so I downloaded & installed it a bit too hastily, seemed fine, my security software didn't show any security alerts. But my device has been acting weird since then. Does anyone know if it's possible that the threat is so well hidden that the security software can't pick up on it? Sometimes when I connect to the tor network, it keeps shutting down, and sometimes the keyboard refuses to work, and it's as if i'm being stopped from typing. anyway any info on this would be much appreciated.

Thanks

if it's possible that the threat is so well hidden that the security software can't pick up on it?

Of course yes. Antiviruses are widely over-estimated.

But what you described here is more likely to be just normal Orbot's behavior.
It consumes 100% CPU & memory, so everything else freezes. Not for slow devices.
