Friend of mine has an XP Pro PC that was recently infected with four trojans. When he asked for help, the keyboard and mouse no longer work when Windows loads.
I have tried booting from a Win7 USB, an Ultimate Boot CD, and other bootable mediums and the KB and MS work fine in any other OS.
I removed his HDD and placed it in my USB HDD dock, ran MS Security Essentials, which found the four trojans and removed them.
Next I reinstalled his HDD and tried to boot to Windows. It loads all the way to the user login, but the KB and MS still won't work. I tried booting in Safe Mode, Safe Mode with Net, Safe Mode Command Prompt, etc. All have the same outcome, no KB or MS.
So next, I tried to do a repair install via the XP Pro SP3 OEM CD. The disc had no issues with the KB during the first step (DOS looking section) and I was able to begin the repair install without issues. But then when it reboots and enters the second step (Windows looking section), the KB and MS still won't work there either!
If I had any hair, I would totally be pulling it out by now. I am hoping to avoid a wipe and reinstall because of the number of programs that we would have to reinstall. As a last measure, I can backup his user profile via my dock and do just that. Problem is some of his discs are at home 300 miles away.
Thanks in advance!
