I recently had avast flag us30kbd2k (located in my windows/system32/drivers folder) as a virus/spyware while scanning my computer. I had it quarantine the file, and when I rebooted my computer my keyboard stopped working as soon as windows loaded. I could still use the keyboard to get into the system settings and change the boot mode before windows loads. After replacing the quarantined file back where it went, my keyboard still doesn't work. When I go into the device manager I get an error message saying that the drivers are installed for my keyboard but it can't find the hardware. I went out and bought a new keyboard (cause my old one was pretty wrecked anyway) and Its coming up with the same error message. I don't think its anything to do with the usb port because I have no issues with any other devices that I plug in. Also, when I plugged in my new keyboard it popped up with a new hardware prompt and started scanning for drivers, for both my new keyboard and the wireless mouse that came with it.For both devices, when the computer starts searching for their drivers, it never stops. I let it run for a good hour or so, and the program just became unresponsive without finding anything. My new mouse works fine even without it finding any new drivers, but the keyboards still dead to the world. Any help would be awesome.

xxm0rt, suspect it can all be traced back to Avast! putting the file in the vault. See if you can use 'restore' to go back? If that's successful, assume you've contracted a nasty which has corrupted the file. Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean , other times, it gets missed entirely. Putting one in the vault renders it unavailable. If you need to clean one, Superantispyware can do the job and you can get it free @: http://www.superantispyware.com/ among other places. They have a Vista compatible version if needed. If it turns out that you need to use it, be sure to update prior to running and disable 'restore' so it doesn't get put back. They just released a new update recently and it changes all the time. Things are in a constant state of flux. That should give you a clean machine. Re-enable 'restore' and try it again. Crossed fingers won't hurt. HTH. Ed in Texas.

alright, I've already tried restoring the file a couple times, it is currently restored to where it used to be. I loaded super-anti-spyware, updated it, did a whole system scan and it said the system was fine. I then selected the us30kbd2k file specifically and scanned it with super-anti-spyware and it came up as clean. If the file is infected, then nothing but avast is noticing it. Having the file restored to where it originally located has had no effect on the keyboard, it's still dead. btw, I've also done 1 or 2 system restores to an earlier date, but those have had no results either
