Accused of placing surveilance ware, need help!!

HELP!!!!!!!! I'm a focile who can trace his user ability to the days of cp/m. I'm not knowledgeable enough to figure out what I did to place a hidden admin acct w/my picture on it in a friends laptop w/ surveillance ware included.

Here is what I did.... Working on a A22m thinkpad with the blue screen of death the only thing that would boot up.

The repair partition was apparantly wiped, the bios would not load the service partition from the appropriate keystroke. Over a course of four or five days. I tried various solutions of reloading drivers and expanding them from the cd rom... I also tried bootable CD's like pe builder and similar programs that were downloaded onto my own Tower and burned with my system.

During this time I also was able to access the command structure on the A22M and tried expanding various patches I found in my search for solutions to the problem of not booting.

After days of trying to solve the problem without wiping the drive I gave up and Wiped the drive with a Win x/p serv pack 2 original disk.

Now I'm accused of trying to spy on my friend and violate her privacy..... I'm not smart enough to show how the offending files appeared on a machine that only I had access too. I'm hoping you folks can help save a friendship and guide me through discovery of how the files, including my picture on the admin account could have been written without my being aware that it was happening.

PLEASE.... I VALUE MY FRIEND AND I VALUE MY INTEGRITY... RIGHT NOW IT LOOKS LIKE I AM A LIAR AND A SNOOP... WHEN IN REALITY i'M JUST A CLOD WITH ENOUGH KNOWLEDGE TO REALLLLLY CREATE A MESS
