I am using Ubuntu 12.04. I am having an alert whenever I start my laptop. "Please enter the login keyring". I do not know why it is coming.
I am having yellow dots on Youtube.
I am fearful that my Laptop is being hacked and somebody else silent connected to my laptop.
or any other threat.
Ubuntu has been slow down (sometimes)
I do not feel secure in Ubuntu.

Please help me if someone from Ubuntu can.
