John McAfee is best known for his contributions to cybersecurity after founding McAfee Associates in 1987 after the first known computer viruses began to appear. Prior to McAfee’s software, viruses were found and captured on computers one at a time. A person would have to install a program to take care of virus “A” and a program to take care of virus “B,” and so on. McAfee’s innovation allowed users to scan and capture viruses in masse. In June of 2021 McAfee was found dead in a prison cell, allegedly from suicide.
