That's simple: nothing is 100 % secure.

Where is the sense in that? If you use encryption properly it doesn't matter
which protocol you use to transmit your data. Changing the protocol would
just mean a lot of work. Where is the problem in MSN anyway? Just because
it was developed by Microsoft it doesn't mean it is bad.

That's always a good thing :)

That's right, but if really want to secure your system that won't be enough.
Bare in mind that security is a process and not a state that you can
achieve. You always have to analyse your system and think about steps to
further improve its security. Updates can only be one of those steps.

Further steps to improve security could be:
- - data backups
- - not to safe data on the computer but on a CD and cut off the internet
connection while working with them.
- - configure a firewall
- - put a NAT-Router between your system and the internet to hide your PC to
the outside world.
