USB Disk Security protects your USB drive from viruses and unauthorized persons stealing your data.USB Disk Security sits in your system tray quietly until you need it. You can right-click the icon to Update as well as Safely Open and Scan the current USB drive. To open the main Windows, you can either double-click the tray icon or right-click and select Open Main window.The main window is called Protection Status and offers safe web navigation with Linkzb.com, which appears to be a safe website. Data Loss Protection allows you to block anyone from copying your data or from connecting any drives to your computer. On the left, you will find other settings which we can look at now.USB Shield will monitor in real-time. USB scan will scan and\or vaccinate your USB drives. Safe Web Navigation is the same as mentioned from the main window but adds the ability to scan a URL with Virus total, Google, Mcafee, Symantec, or Trend Micro. The Data Protection tab is the same as Data Loss Protection from the main window. System Tools has Disk Cleanup, Repair System, and Autostart List. It's not clear what Repair System does but Disk CLeanup appears to clean your browser cache, and Autostart shows startup items and allows you to disable them. Finally, Quarantine shows any unsafe files that have been encrypted and moved to quarantine.Last, but not least there is a setting link that allows you to set, or change, your password as well as choose from 13 languages.There's a lot of choices in apps that protect your USB drives, but USB Disk Security has enough settings and tools that others lack giving it a professional feel.
