How do I go back and get my same facebook and same levels on games I mastered before cleaning files from my desktop? after rebooting I lost everything is it possible to retreive?

I have desperately tried asking Facebook to give back my same profile. After restart but they can't seem to see any reason why they  should. I have A brother by the name of Sean Rankin Another named louis Jr and me louis rankin we are all on face book. It seems if we get an antivirus we could never get back to where we were. So I ask anyone Is It possible to retrieve my information after I have (cleaned) my computer of unwanted files for better performance.  I have really been enjoying about 10 separate games and have done quite well. I would like to continue on with the same levels.
