xp is notorious for not letting you play old football games over 5 years old.
what you need to do is go down the shops and buy pro evo 10 or fifa 10.
or you can reinstall them, or replace the exe with a no cd version.
it should take that long to install, those are relatively old games, and wont need more than a gig to install, so you're looking at 5-10min max install time for each.
have you tried running malwarebytes?
that should find anything that's on your pc
