edit: a quick example of how the search could work
while_i_am (searching through your computer files) //at this point your OS will report each file as 'accessed' from esea's anticheat
{
   if(the_current_file EQUALS the_hack_we're_looking_for)
        Upload_File_To_ESEA; //Great! We found a known hack on the PC, ban this player
   else (the_current_file ISNOT the_hack_we're_looking_for
         Skip_File; //File is useless to us
}
