I plugged in 4 devices.
I was able to immunize 3 of them from the right click context menu, but the fourth item did not have this option in the menu.
What does that mean and how do I immunize the USB?
Windows 11.
Hello.
If the drive has already been immunized, the message The USB device is protected against autorun-based threat will appear instead of the Immunize option.
If you don't see that message, you should contact Bitdefender Consumer Support by chat, telephone or e-mail:
Chat is the fastest way to get in touch with Bitdefender Consumer Support.
