Block USB Tool is a useful application that protects your computer against many threats regarding malware inside USB drives. This tool can partially or completely block USB reading features. Block USB Tool can be configured for use on your home computer, or in an office with several systems. Select among three different settings for a secure USB reading experience. The first option is Read Only and allows you to see USB content but does not let you add new files; preventing harmful USD files from jumping into your computer. Another more secure option is to Disable the USB drive. By activating this option you cannot use USB drive or view its content. The third option is Enabled, which is the same as the default configuration of your computer. You can protect your documents from malware while using other USB devices such as the keyboard or mouse without any problem. Block USB Tool is yet another barrier for protecting your computer from threats.
