Step-by-step explanation:
The most common threat to information security in an organization is computer viruses. Computer viruses are malicious software programs that replicate themselves and spread from one computer to another, causing damage to data and disrupting normal operations. They can be introduced to computer systems through various means such as downloading files from the internet, opening email attachments, or visiting infected websites.
Computer viruses can steal sensitive information, corrupt files, or render systems unusable. They can also serve as a gateway for other types of attacks, such as ransomware or spyware.
