Projects >> USB Defender

MOST POWERFUL application to protect you from autorun viruses!
Did you ever wonder, why is anyone talking about so dangerous USB drives? Why can't you protect yourself from thousands (!) of viruses that are spreading only by your flash drive? Today there are many programs that can be in your memory, waiting for any new flash drive connected, finding viruses on it and removing them. But isn't it better just to VACCINATE your drive once and forever? No more viruses. No more danger.

About this program. Short FAQ.

USB Defender was developed to be extremely easy in use. You can see just two buttons on it: "Protect" and "Unprotect". First button you are using to vaccinate your drive, second - to remove protection. After selecting any drive, program automatically detects, if there is any protection active and only one button will be available for you. Also you have a checkbox there, which is to choose, what level of protection use. If you put a tick on it - you 'll need administrative rights on your PC to protect (and then, if needed, unprotect) USB drive. BUT using Pro way of protection is MUCH more secure and protect you with 99.999999999(9)%.

Also, you can see a mark of your USB protection. If you don't use Pro method, you can't achive 5/5 protection but you'll be able to REPROTECT flash whenever you'll have admin account.

If there is any autorun.inf file on your drive, corresponding sentence will start blinking. This was done to warn you, when you are going to protect drive with AUTORUN function, that may be useful (like running menu program at moment stick is inserted).

USB Defender is fully portable - so you can take it with you wherever you want.
