i recently found a malware that changes bitcoin addresses when copied to the hackers address so just watch out and check to make sure that the bitcoin address you copy comes out the same when you paste it 
never know about this case and kind malware like that,its terrible hacker,i dont think its can be done by hacker,they should be pro and smart hacker.thanks for sharing,even you dont put any proff,but its make us know about new case in bitcoin hacking.
