so i accidentally downloaded a token logger which apparently logs all my passwords too, this dude who sent me this said he has full rdp access to my pc.
theres nothing suspicious running on the taskbar and i ran virus scans with both malware bytes and hitman x64. nothing found...
what can i do...he already hacked my discord and sent some stuff to random people but i changed my password. idk about the other stuff he said tho
