Keyboard Driver Deleted

I'm typing this from my brother's computer because my current computer's keyboard is not working. Not sure if this is the right place, but I really need some help on this. This is what happened:

Kaspersky Anti-Virus said that I had a keylogger on my computer entitled ps2, so naturally I deleted it. For some reason, I was curious about what ps/2 was specifically, so I searched the web. It is actually the driver/program that allows my keyboard to function. Now, I can't log on to my computer, because whenever I try to type my pass, it freezes. I can log on in safe mode, but still, it freezes if I use the keyboard. I can still run applications, and go through files and folders, but I can't use the keyboard at all.

Does anyone know what I can do?

 

Edit: Nevermind I have fixed it by using application recovery. Thread can be deleted.
