I run Elyssa and have a symbol of a padlock at the bottom right side. This is for updates on software. It tells me that I have 351 updates available. when I open this the updates are shown and each have a number.Mainly 2's and 3's. when I do press the install update button, it gives me the following message:
warning you are about to install software that can not be authenticated....
This message worries me so I have not done any updates for a loooooong time.
What shall I do? How can I tell what is malicious and what is not? does anyone out there know?

As a general rule, it is safe to update using the tools and repositories for the distro. Keep in mind that only what you have installed will get updated. The time to be cautious is when you first INSTALL something. But, again, if it supplied by the distro maintainer, it should be OK
