This is not quite correct. The idea of open source is double edged,
vulnerabilities are exposed to those who would readily exploit them, and
also tho those who would readily fix them. Virii for Linux exist, as
proof of concept, but have not yet been found running in the wild. The
security model that Linux (and Unix) has long imposed means that your
normal user account could only allow damage to things to which it has
write access, and that rarely includes scripts and executable.

Updated software is always a good idea, as many updates are security
related, however you need to add to that, only using root access
whenever it is actually necessary.
