I scanned my system with Malwarebytes today and located the directories of several viruses. I used NotePad++ to open the executable files and deleted all the code written therein and saved the change to the virus. I proceeded to delete the viruses with Malwarebytes; but, I wondered, had I left the viruses changed with no code, would they still be able to execute their program? My thought is, no. But, I would like to get a better understanding why or why not from those who understand computer viruses. The name of one virus specifically, Trojan.Happili, if that helps.
