👉 A laptop infection occurs when malicious software, such as viruses, worms, trojans, or ransomware, infiltrates and compromises a computer's operating system or applications. This can happen through various vectors, including infected email attachments, malicious websites, or compromised software downloads. Once inside, the malware can steal sensitive data, corrupt files, slow down the system, or even lock the user out permanently. Infected laptops can also serve as entry points for hackers to gain access to other devices on the same network, spreading the infection further. To prevent laptop infections, users should keep their operating systems and software up to date, use reputable antivirus software, be cautious with email attachments and downloads, and avoid suspicious links or websites.
