USB disks (like pen drives, external hard disks, memory card readers) are extremely popular nowadays. But they can expose home and office PCs to certain risks such as computer viruses, unauthorized data duplication and so on. USB Security Suite is the ultimate toolset to eliminate security risks related to USB disks. USB Security Suite automatically scans (and cleans if desired) USB disks when attached to your computer to prevent viruses from infecting your system. It completely analyzes autorun files and warns you if they are suspicious, and provides quick options to take necessary actions. It can also vaccinate your USB drives, so that they never get infected by viruses even if you connect them to an infected PC or device. If you need to know what activities (copy, rename, delete) happen on USB drives connected to your system (to see what other people and/or programs do), USB Security Suite can monitor and log them. The Activity Log can be searched or exported to well-known formats for later use. To prevent data theft, you can easily disable the usage of USB disks on your computer. USB ports can be locked, or unlocked at any time with a single click. Of course, you can still use your USB printer or scanner even when USB Lock is activated. Critical parts of the program are protected by a password, so no one , other than you, can change settings, read activity log or unlock USB ports. USB Security Suite covers every aspect of security regarding USB disks.
