Very similiar to http://www.bleepingcomputer.com/forums/topic31163.html and followed instructions in KaZoom's response - did not find files in "You will see a couple of 'StBcWXYZ-like'.ini and ini2 files - about 500KB in size, with a somewhat random-looking name with the datestamp of the moment when you got infected. Also, you will see several (8 gibberish lettered name).dll files with lengths between 60KB and 250KB".
Also went to http://www.kellys-korner-xp.com/xp_wel_screen.htm, but got stopped at "In the right pane under Userinit, Change the key to read: "C:\Windows\System32\Userinit.exe" because that was correctly entered already.
Created a second user, but didn't transfer any data to that user.
Can access Safe Mode okay.
Could reformat hard drive, as I don't need any documents, but don't have an operating system disk to reload OS.
Don't know where to go from here.
