problem after recovering system on my laptop

greetings my name is nigus,
i need a little help if anyone can help.i m a bit confused.
i own a compaq presario laptop,and it got hit by several trojans in succession which left a bit of damage to my internet and system in general.
today we copied all my files and put them on an external hardrive which was fine, and ran the system recover which is part of the computer when you buy it.
basically restored the factory settings.
a pop up said in the instructions that everything would be reset but my data would be saved.
GREAT i thought.

so after all the checks and reboots were done, i check my c drive to see the capacity and its total space 60GB
free space 21GB
or something to that effect.
going into my documents and there is nothing there.notnhig in my music or any other file,
my programme files still exist and have to be registered and all that.
but its weird because the system is taken up as if it was full of all my files but theres nothing there.

basically theres 30+GBs of data gone missing from my computer.

one person said to me it was ghost fiiles..but i know nothing about that.
and another game me a programme "easy recovery pro" for getting back the files.
but nothing seems to work.
i know nothing about ghost files so i dont know wat to say really.

has anyone here any ideas? i would greatly appreciate it.
many thanks.
Niall

i ve run several searches and cant find anything
