I have a suspicious usb flash drive and i decide to scan on an isolated computer before use it. I update the antivirus and then disconnect it from the network to be sure nothing wrong can happen.

The scan start and finished in 1 second. He gives me a lot of object cannot be opened almost to all files in the usb. The files are generally pdf and xlsx. Is this normal and why that happen?
