I recently had my computer attacked by a trojan virus and after about 12 hours of worked I was able to remove it, keep everything exactly how i had it, settings, files, bookmarks, etc. Except now, I'm having a problem with my printer, it can't be found and can't recognize any new hardware either. I looked in the services and it said the Universal Plug and Play Device Host wasn't started, I tried starting it and got error 1068. So I checked the depencies and it depends on the service SSDP Discovery Service...so I tried starting it...I get the same error, but on that dependency it just says HTTP, which I know is the kernel for http.sys. However, does anybody have a clue on how to fix this? Do I just need to download SP2 even though it worked fine before and I've never had it.

Here is a good start for you.
