Hi there. I’m at work right now, so I won’t be able to try the recovery mode until after 6pm CST this evening. I’m not sure what you’re referring to about my configuration, but I have Windows XP Pro-Service pack 1. I didn’t go to Service pack 2, because I thought it could create problems. I never had the check_LSA7 text file before showing with other folders on my C (hard) drive, and when I right clicked and checked properties, it was created in September 2007, so I suspected it was part of the virus. I purchased my computer in 2004, and the majority (if not all) of my system files have 2004 creation dates. I could not delete, nor could I read the check_LSA7 text file before using Combo fix and No Lop, because I received the message “In use by another program or user…” I suspect my problems of rebooting started happening, either when I did the registry fix, or possibly when I deleted the check_LSA7 text file. I deleted the check_LSA7 text file and did the registry fix all at the same time within a couple minutes, before trying to reboot again. Also, I did reverse the process and hide the operating system files with the 2 or 3 checkboxes like you had suggested. Thanks.
