Most Linux users may claim that they can never fall prey to viruses, Trojans, worms, spyware, phishing and other Internet attacks; however, the reality is different. Linux is no harder to break into than a Microsoft Windows operating system. Even though the Linux platform may not be targeted directly, it can act as a malware carrier and cause serious damage to Windows-based systems in the network. Therefore it is vitally important that every single endpoint user within a network uses an antivirus solution providing this multiplatform protection. ESET NOD32 Antivirus 4 for Linux fulfils this task.
