how to remove parental control

[LiNuX]

anything?

reinstall your OS - best way to get rid of it

most likely your mom installed the parental control on the administrator account of the computer - if you can get access into it then you may be able to uninstall the software -

but I vote for wiping hdd and restarting - you'll get rid of a lot of other crap that could negatively affect your computer.
