A PC virus is a type of malicious software that can infect and damage a computer system. Viruses can spread through email attachments, downloads from the internet, or USB drives. Once a virus is on a computer, it can replicate itself and spread to other computers on the network. Viruses can cause a variety of problems, including data loss, system crashes, and security breaches.
Creating a PC virus is a complex and dangerous process. It requires a deep understanding of computer systems and programming languages. Creating a virus can also be illegal, depending on the jurisdiction. If you are caught creating or distributing a virus, you could face criminal charges.
