Everytime I turn USB WriteProtector ON. liberkey.exe cannot run from the USB stick.
I don't want virus infects my USB. But I cannot use liberkey when USB WriteProtector ON.
Any suggestion?

Open LiberKey\Apps\USBWriteProtector\App\USBWriteProtector\UsbWriteProtect.exe and turn USB write protection OFF.
You can't use LiberKey with read-only media.

I understand that.
My question is: how do I protect the USB from virus and use Liberkey same time?

You can use encrypted USB partitions

Thank you.
