security of the universe repository

I think the OP is referring to the fact the Universe / Multiverse
repositories are not supported directly by Canonical, but by the community.
So the OP, being a long time Windows user, I guess, assumes it is
potentially open to malicious code...

Chandra: No need to worry!

Although Linux viruses exist, they pose very little threat to your Ubuntu.
On the other hand, if you use the same computer with Windows, and download
files from the Internet, make sure to scan them regularly with an updated
Anti Virus. You can safely install ClamAV + ClamTk (it's graphical
front-end) and use it to scan your Windows partition from within Ubuntu.

The fact that the  Universe / Multiverse repositories are not supported by
Canonical just means you have to seek the community's help and support for
the applications you installed from them, and not contact Canonical.

I hope I was helpful and didn't confused you even further ;-)
