On a client's computer, XP Pro SP2, I've been getting pop-ups that are titled RegSvr32, error on a driver file. dmfuputm.dll kdyvideb.dll onerofsh.dll cxzwrajwx,dll At location C:/Documents and Settings/All Users/ApplicationData. The problem with these dll files is that I googled them and Google didn't find anything on them. I went to the file location, had show hidden files enabled, and they weren't there. If they were malicious driver files, possibly Ad-Aware had removed them so in a way maybe the computer is still looking for these registered dll files. Can anyone explain to me the best way to go about this? And what exactly does that error message mean?
