VirusScan, otherwise known as McAfee Antivirus is the best safeguard measure to minimize and prevent virus attacks. With Thecus VirusScan module, users can rest assure that their vital data is protected with advanced features to eliminate possible threats. Thecus NAS now comes with free McAfee VirusScan module for maximum data security. McAfee is a wholly owned subsidiary of Intel Corporation and is the world's largest dedicated security company, offering industry-leading, award-winning product which is a reason why Thecus decided to partner with them. Typically computer users already have antivirus software installed on their desktops. But NAS has its specific characteristics which require additional protection. For example, every time a user sends a file to a shared NAS device, there is possibility for spreading virus infection and other malware throughout the storage device, data center, and entire network. Now Thecus NAS users can enjoy McAfee security for free! VirusScan module is now available on N5550 and TopTower Series, other models will be released soon.
