Correct, Mr Spock.

He's right. To the general public the word virus and malware (as we
would say) are synonymous. They're not interested in the differences
between a virus, worm, trojan or PUP; to them they are all viruses.
For some reason the words "computer virus" have become the all
encompassing term that we would call malware. Yes, "malware" does
include viruses if you accept that viruses are malicious.

WRT R Lopez's OP; it is very easy to create an executable that has a
unique signature on every download. There is no need for any special
encryption techniqes. One way would be to build an executable with a
section that is never used and fill it with random data. A script on
the server then generates a random section and puts the thing together
when the file is requested.
