hidden applications

[XeeR]

Hi guys

I have galaxy s II , It seems OK but I have a problem with some unknown applications
when I go to the task manger by keeping clicking the home button there are not any active applications but when I go to the RAM side and I click clear memory it shows that some application have been closed ( some times 5 , 9 or 12)However theses application can not be seen in the active applications.
are these active application dangerous and affect the device?
How can I know these hidden applications ?
How can I stop them for ever ?

by the way my device is new and I did not do any illegal things to it

the apps that you are closing are probably part of the android system and they need to run for android to work properly. they will automatically start up again as soon as you shut them down. just stay away from task manager, you'll be just fine. here's a thread that should provide a lot of info on the subject.
