Virus
Computer viruses are programs that damage or disrupt normal computer functions. They attach themselves to files and replicate, spreading infection. Viruses can be transmitted via email, downloads, disks, and networks. Different types of malware include viruses, worms, Trojan horses, and hoaxes. To protect against viruses, users should install antivirus software, regularly update definitions and scan for viruses, avoid opening suspicious email attachments, and use firewalls.
