I have just returned from a 3-week vacation. When I turned on my home computer, everything looked great. Unfortunately today, when I restarted, I got a mysterious message -- "winlogon.exe is unable to locate a component -- sfc__os.dll is missing." I was prompted to reload this file.
I eventually restarted the computer using my xp disc, and it loaded okay. I did a search for the "missing" file and it appeared to be (back) in my windows\system 32. However, just to be sure, I restarted again, only to find the SAME problem. In addition, I discovered the computer seems to have lost all printer/peripherals information.
This is my first experience with a virus, and my husband sagely suggests that a trojan horse has most likely made its way into my computer.
Can anyone provide advice as to how to fix this? I am trying not to panic, but fear I am losing the war.......
