What happens if a virus infects a computer without an antivirus?
If a virus infects a computer without an antivirus program, it can delete files, prevent access to files, send spam, spy on you, or perform other malicious actions. In some situations, a computer may not meet the requirements of a virus, and the computer is only used to help spread the virus to other computers that can meet the requirements.
