In 1984, Dr. Frederick Cohen introduced the term “computer viruses” in his research paper titled “Computer Viruses – Theory and Experiments.” Before that, there was no name for bad coded that infected your computer.
And, just as human viruses, computer viruses are self-replicating programs that spread from one host to another. Computer viruses are classified based on the object they infect:
File infectors: There are direct and memory-resistant viruses. Direct infectors immediately infect files as soon as they are executed. What do they do?
- They overwrite host files with their own malware code resulting in the total destruction of the host file.
- As companion viruses they become extensions the host file and then create a copy of itself with the name of the host file. The renamed host file uses a hidden attribute so it does not show up in the computers directory listings.
- Or they attach themselves to the host file during infection (parasitic viruses)
Memory-Resident Viruses: These viruses do not infect files directly upon execution, but hide in the memory until a host program is executed and then infect it.
Boot-Sector Viruses: True to their name, this group of viruses infects the boot sector of a disk to get control of the computer system's execution flow even before the operating system. It basically hijacks the first instruction in the boot sector to point to itself.

One of my clients was excited to launch a new product. It was unique and made people’s life easier, a good story. They asked for a new webpage and themes for their campaign.
