Warning! Your antivirus or firewall programs may not recognize the running programs, so always give access to them.
On some antivirus scan, keymaker can reveal "Suspicious File", "Potentially Unwanted Program", "Type_Win32" or "Trojan_Type" virus etc.
Don't be stupid, it's not a virus or anything else like that.
Just some packers/cryptors which have same binary signature.
