TAILIEUCHUNG - LAYERED NETWORK SECURITY: A best-practices approach

Attackers can infect your computer with malicious software, or malware, in many different ways. They can take advantage of unsafe user practices and flaws in your computer’s programs (flaws including vulnerabilities and unsecured services and features) and use social engineering (in which an attacker convinces someone to perform an action such as opening a malicious email attachment or following a malicious link). Once your computer is infected, intruders can use the malware to access your computer without your knowledge to perform unwanted actions. They can steal your personal information, change computer configurations, cause your computer to perform unreliably, and install. | gStillSecuré Reducing your risk has never been this easy.
