Need help removing a ......script ???

In my sons history there are what I believe to be 3 different scripts I can not get rid of.
I have run AdAware
Panda Plat.
Spybot.
Nothing there.
I also tried to remove them in safe mode.
It says file not specified.
I tried to rename them and delete them with the same results.
They came from some web pages he visited.
I think one was rotten tomatoes or something like that.
What is next??
Hijack This scan ??

Compaq 450
win xp sp1

It seems like his username has taken over the admin functions also.
Any help is greatly appreciated so thank you in advance.
Here is the pic.

 

Hi MD Rotten Tomatoes is a movie review site, and the data listing sure sounds like it's movie relevant. Maybe you can find the files in his favorites section and delete from there? Can you re-access administrator functions from Control Panel?

 

I just finished searching his files.
There was no mention of Rotton Tomatoes there.
I might be wrong about that, I am not sure.
About the admin rights , I was trying to say that when he downloads something it now goes to all users.
It used to be we were able to download and keep it as personal settings.
Now he is downloading all the mssng services because I keep deleting them as I do not want or need them in my settings.
I hope this clears that up.
I am sorry about the confusion but I had a hard time trying to figure out how to say it and keep is short.
