Malware, short for "malicious software," is designed to gain unauthorized access to computers or networks for purposes such as data theft and surveillance. It can be introduced through disguised software or deceptive links. To protect against malware, it is essential to install antivirus software, scan external drives before connecting them, be cautious about downloads, avoid suspicious websites and emails, update applications regularly, enable Tamper Protection on Windows, minimize file sharing, enable Firewall protection, watch out for phishing attacks, and back up data regularly. The future of malware protection may involve leveraging artificial intelligence and machine learning to enhance detection and analysis of threats.
