Error message: A new USB device with keyboard functionality has been connected

Maria Hakonen

Hi,

Sophos is giving me the following message:

"A new USB device with keyboard functionality has been connected:

USB Receiver

Malicious USB devices may pose as a keyboard to install malicious software and enable an attacker to remotely take control of your computer.

Click on block if you did not connect a keyboard to this computer or do not recognize this USB device"

The message consistently appears on startup and sometimes also while I am using the computer. I have always clicked block since I haven't connected a keyboard or USB device to my computer. 

Could someone please let me know how to solve this problem?

Many thanks already in advance!

    Same thing happened to me. But, since I had a wireless keyboard attached, I clicked "allow".

    After that, my wireless keyboard stopped working. Then I rebooted and got an error message saying something like "Network can't be reached. Click here for help."

     

    The minute I saw the blind "click here for help" link, I shut the machine down and came here.

    The warning could be real. Right now, I am keeping the suspect computer turned off until I get a resolution.

    One further fact: the warning came upon waking the computer up from sleeping, not from starting it up cold.
