Keyboard no longer functions after plugging in external keyboard

 After plugging in my external keyboard, both my external and laptop keyboard no longer function. The keyboards cannot type or execute shortcut commands. When clicking download links it results in downloading download.htm. This problem persists after unplugging the keyboard but only seems to begin after the external keyboard has been plugged in. After a restart computer use without plugging in the external keyboard results in no issues, though I haven't done so for extended periods of time. The external keyboard functions normally when plugged into another computer, though it was a Mac, so I'm not sure if the different operating system could have an effect here.

 

I've run a Malwarebytes scan already and it didn't pick up anything. I think it's likely a virus, but I can generally just use Malwarebytes to solve the vast majority of my problems so I don't know where to go from here. At the moment I'm running a Spybot search and destroy scan to see if that picks up anything Malwarebytes could have missed.

 

Any help would be appreciated, thank you.

 

Edit: Spybot managed to pick up and delete a virus called win32.downloader.gen, I also ran TDSSkiller and picked up no root kits. The problems still seems to occur.

Try a System Restore to a time before the problem began. If you have such a Restore point available.

 

1 - Restore:

The only restore point that exists is one that was made today.

 

I think the virus or whatever deleted my restore points as I remember creating a restore point a few days earlier before installing a Windows hotfix. 

 

This new one was probably made by whatever is causing problems, so I don't think I should trust it.

Have I got this right?

1 - Both keyboards are knocked out when you plug in the external keyboard

2 - the built in keyboard works normally when you unplug the external keyboard and reboot.

3 - clicking download links .. results in downloading download.htm

Your best bet at this point is to start a topic in the 'Am I infected?' section of BC since you have some evidence of infection.

 

In your new topic give details of your computer and OS as well as details of any scans you have run and the results and include a link to this topic - copy and paste the URL at the top of the page. To avoid confusion I am going to close this topic but if it turns out that it is not a malware problem you will be most welcome to come back and start a new topic in Win 8.
