Has the entire AV industry been wrong since its start?


I had an interesting read about a blog post of a famous researcher Joanna Rutkowska did...Her last blog was about how, in her opinion, security companies and especially antivirus companies are basically wasting their time developing antivirus products when they weren't useful but, instead, a digital signature could fix all problems for file infectors. Basically, a digital signature could assure us that the file we are going to execute isn't modified and, thus, isn't infected by a file infector virus.

If this would be true, anyway I sincerely wouldn't say antivirus companies wasted their time and money developing useless techniques. Has the entire AV industry been wrong since its start?
