Hi, I just ran F-Secure Blacklight on my computer to check for possible rootkits and came up with one hidden file called con.nbg. In addition, in the list of processes running, there was one hidden process called vssvc.exe. Do I have reason to be concerned? Can I safely rename the con.nbg file? I did a search on both. Nothing on the con.nbg. the vssvc.exe shows as maybe being a hidden process that microsoft has. I'm a non techie, so this doesn't mean much to me. The computer is a one year old Dell with updated windows xp and appears to run fine most of the time. I do get an occasional hang which I have always attributed to having too many things running at the same time. Many thx for any help.Rob
