Question

what is a computer virus how does it spread​

Answer 1

Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected e-mail attachments. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.
