Bit off topic, but in some sense, I really miss old DOS/Windows virus scene.
A lot of people was writing viruses just for fun, and they were inventing very clever technics, such as polymorphic/metamorphic code or advanced anti debugging/disassembling tricks (which nowdays you can find in Denuvo :D ). Nowdays most of the malware are just money grabbers without any art in them, as a proof of my words - till now nobody were able to beat Z0mbie's "Zmist" from 2002
