my proof is inductive reasoning.
you have linked 0 drawing editor files before.
you have given malware 0 times.
that's a 0/0 average, which is undefined.
undefined is no less than 1, which means that your average of drawing editor files to malware is 1.
personally, I'm not taking the risk of malware from you, given that 100% of your previous drawing editor files were malware
