Have you ever downloaded and run software that exploited your Bitcoin wallet? What software was it and how much Bitcoin have you lost?
Do not post URLs please, just write your experience ))
When I was young, I downloaded a "Steam account cracker", which of course was a nasty trojan and not in the good meaning. Fortunately, I haven't lost Bitcoin from the case. Maybe because I didn't have any that time

But my system behaved very strange and after virus removal, I had to change all my passwords.
I am usually very cautious about what i download an actually only keep a minimum amout of bitcoin on my core wallet, everything else on encrypted paper wallets
I have a few sloppy wallets on my desktop named "bitcoin and private key" the file actually contains an address and priv key which i monitor, the idea is that it would go first if i had bitcoin stealing malware. lol or an attacker with access to my computer.
