OK...let's see if we can make this simple...I'm confident it won't work, but let's give it a shot
Have her...and she can do it in save mode if it won't let her in full mode...bring up the Start/Run and type 'msconfig' (no quotes) and uncheck anything she can in 'Startup' section. You'll have to guide her here, but she should be able to disable almost, if not all of the items. The idea is not to have anything running on the re-boot (except MS System Files) and it should still allow her to get on the net to kill this thing. Let me know....
