I posted this on the External Hardware forum but did not receive any responses in two days so I'm hoping someone here can help. I am running Vista Home Premium.
After 2 days I believe I've finally removed the infections off of my computer but am still facing a problem where the external keyboard no longer works (I'm using the on screen keyboard for now). Ths has been the case both in normalmode and safe mode. Doing some initial research, similar threads suggested looking into the registry editor for the Upper Filter for key 4D36E96B-E325-11CE-BFC1-08002BE10318- for reference I'm looking at this thread: http://www.bleepingcomputer.com/forums/topic278884.html.
The only value data I see there is 'kbdclass'. I'm not sure what one would expect to see here, so any further help/suggestions are greatly appreciated. If there is other diagnostic info I can provide please let me know.
