Can trojans disable USBs?

Ok this is pretty weird. I was on my laptop and I received a pop up saying that I have been infected with a trojan and blah blah. Then I noticed that my mouse is no longer working when I reset the laptop.

( obviously its a USB mouse, it's wireless too. )

I tired other USB ports and nothing. I have nothing else that I can try ( that is usb ) to see if the mouse is just dead. But its not that old, so I dont think the mouse stopped working. And yes I did replace the battery and see if that would work. Nothing.

So, I'm wondering can the Trojan disable the Usb? Is there any way to check to see if the USB is still functional?

 

Replace the mouse with PS/2 mouse,and visit our malware fighters to remove this nasty out of your comp.GOOD LUCK!!!!

 

so then I am guessing that a trojan CAN disable USB ports?

 

Yes.
