Ransomware is a type of malicious software (malware) designed to lock or encrypt a victim’s data and demand payment in exchange for its release. It can cause severe damage to personal and business files, leading to significant financial loss, reputational harm, and operational disruption. As the threat of ransomware grows, it’s essential to use preventive measures, and Windows offers built-in protection tools to help safeguard against such attacks.
