A computer virus is a type of malicious software (malware) designed to replicate itself by attaching to legitimate programs, files, or boot sectors, spreading from one computer to another without the user's knowledge. Once active, it can damage files, disrupt system operations, steal data, or create backdoors for attackers.

To stay safe from computer viruses,

Install and update antivirus software: Use reputable anti-malware apps that offer real-time protection and keep them updated to detect the latest threats.

Exercise caution with emails and downloads: Never open attachments or click links from unknown or suspicious sources, and verify unexpected files with the sender.

Avoid risky websites and software: Do not download unlicensed applications or visit compromised sites that may trigger drive-by downloads, and keep your operating system and apps patched.

Use firewalls and backups: Enable firewalls to block unauthorized network access and regularly back up important data to secure, offline storage to prevent loss during an infection.

Disconnect if infected: If you suspect a virus, disconnect from the internet immediately to stop the spread, then run a full scan in Safe Mode to remove the threat.
