Windows 7 Hot Key - Virus Related ?

When we type " l " over a remote session or using windows on board keyboard, it does an " l " as desired.

When we type " l " on the actual keyboard attached to the PC, we get a " a,l8 " key combination for every l we type.

No other key seems to be acting up .   We had major virus activity and  cleared them using malwarebytes.

I have searched google over and over and cant find a way to delete hot keys.

I ran a google search on a hotkey finder program and it stated there were none foud..

BUT.. something is going on ... ughhh Help

First try another keyboard, or boot another OS (such as a liveCD, or an OS installed onto another drive). I'd wager that the keyboard may just have an issue. It would be especially telling if you tried that keyboard on another system, and the same results happened.

RegW2.exe located down in C:\***\syswow64.

Panda Cloud "supposedly" cleaned and rebooted.

Problem remains.

Tried a new Keyboard , it works great.

Took "hexed" keyboard to a new machine and it TOTALLY blew my mind that it had the same key duplication issue on a new machine.   I dont understand how a virus could get into a wireless keyboard and mouse.  This was a logitech .

The scary thing is , now I have another person with same issue but its a Microsoft wireless K and M.  

To fix the first lady , I bought a new K and M and wiped her OS and reloaded.   I just cant figure this one out.

I don't think that the keyboard is "infected". It likely just broke around the same time as the computer got infected. Most keyboards aren't possible to change anything on, its all set in and unchangeable.

Keyboards wear out all the time. I've gone through quite a few over the years. This laptop I'm using now is 2 years old and is on its second keyboard.

Keyboards aren't that robust anymore. they're basically a think piece of plastic with traces  on them sandwiched with a second sheet with holes in it, and another sheet with traces. On top of that you have a rubber mat with suction cup like bumps over each of the spots where holes are in the sheet. So when you're pressing a button, the rubber smashes the sheets together at that spot, so the traces from the two sheets touch there, completing the circuit. You release the key, the rubber goes back to its normal shape, releasing the pressure. Over time, the materials wear out, so you have random key presses and such. Plus, keyboards are designed with "multiplexing", a circuit design method that lets you have a handful of connections for a bunch of different things. Most keyboards I've worked on have had 4 or 5 buttons on a single trace, and so if that portion of the sheet with the holes starts wearing out, the pressure can make it act as if you're pressing multiple buttons.

You mentioned in your last post that they're wireless keyboards. With that you also open up for radio interference, and bad transmitters or receivers.

Lots of points of failure.

i dont know.  How do you explain me leaving that hguse , coming home, hooking up that K and M on a freshly loaded PC as a test and it did exact same key repeat as it did at house with infected PC.

That really blows my mind.
