Add & Remove Problem

I loaded some software onto my computer last week and I worked with it
for a couple of days. Now I want to remove the software as it seems
that what I have is illegal to have.
I went to Start > Control Panel > Add or Rempve Programs. What I get is
a screen showng about 8 programs that are installed and they all begin
with the letter A. I then have to scroll a long distance down before I
see trhe next programs which happen to be Dell products. Nowhere do I
see the product I am looking to delete. I have tried sorting thr
programs by 'last date used' and still no luck.
A couple of questions:
Why do I not see the program I am trying to remove?
Why is there such a big gap between the first part of the listing,
those programs beginning with A and the rest of the programs?

Thanks for any and all help.
