this probably is a case of a bug in ur device so what u can try are: plz make a back up
take out your sim card and put in *#7780# to restore factory settings. you should not lose any data, but all settings will go into default. try that first.
the second option is a reset *#7370# this one will erase all of your data, 'wipe the phone clean' and restore to factory settings. see if any of these options work and if you are able to use your phone as you like/need to.
the third option U can go in for a hard reset which will turn ur device as it left the factory totally new
U can also update/reinstall ur firmware and see the result...
Also use ur device without the memory card and see
in case of ur memory card there are different options available to you to get rid of the corrupt/unwanted data in your card.
menu--tools--memory---options---format memory card......
remember everything including ur factory installed apps will be deleted......... but u can always download them later either from nokia or google them...
or insert ur card in any reader or laptop and check for virus and also the hidden folders.......
