• Security breaches: Viruses can compromise the security of a computer system by stealing sensitive information such as login credentials and personal information.
• Spam and pop-up ads: Viruses can display unwanted pop-up ads and send spam emails to contacts in the infected computer's email list.
• To protect against viruses, computer users should take several preventive measures, such as:
• Using antivirus software: Installing and regularly updating antivirus software can help to detect and remove viruses from a computer system.
• Being cautious when browsing: Users should be cautious when browsing the internet and avoid clicking on suspicious links or downloading files from unknown sources.
• Keeping software up-to-date: Users should regularly update their operating system and software to patch security vulnerabilities and prevent virus attacks.
• Using strong passwords: Users should use strong passwords and change them regularly to prevent unauthorized access to their computer system.

In conclusion, a virus is a type of malware designed to infect a computer system and cause harm. Viruses can cause data loss, slow computer performance, security breaches, and display unwanted pop-up ads. To protect against viruses, computer users should use antivirus software, be cautious when browsing, keep software up-to-date, and use strong passwords.
