This is wrong. Malware authors put in a lot more work to make their software look legitimate, even including valid version information and digital signatures.

Hmm, but if I was a malware author and legitimate software couldn't bother to put in version information maybe I should also not do that so I can blend in better.

That might depend on whether you prefer to look unremarkable once you've attracted someone's attention, or to just not attract people's attention.
