Ah yes! Yahoo! Mail really sucks. It locked up my inbox once for a few
weeks for no reason (seems they have some glitches in their AJAX-based
frontends. Didn't bother to try the old HTML version and switched to
GMail and has been very happy with it up til now (disclaimer: I'm
interning with the company that made gmail so don't take my words d:
just try it! ^^)

That's not true. Linux PCs are easily hacked if you're really into it.
The thing is not many people comes up with rootkits for it, so not
many script kiddies could hack Linux PCs. Basically you need real
knowledge. Linux is a lot safer than Windows, but it is not
unhackable. And the reason why there's no commercial security product
(or very few of them) is because Linux has user-configurable firewall
built into the kernel (iptables). And since it is script-based
(command line based, but usually you'll come up with a script to run
on system init), a lot of people write a third-party, also open source
software, to generate such scripts (I believe ufw does this).

Hmm. Generally, still a good idea to scan once in a while. Unless you
use your computer responsibly (I've used Windows PCs for 3 years
straight without getting any virus before I fully dumped it since I
lacked disk space).

Not true. Linux iptables is a router! So you don't need a router. In
fact, many people use an old Linux desktop to serve as router for
their home LAN. It is a lot safer than those embedded system router.

rootkit check is a must, definitely. (:

Hmm. Seems to be losing ground here with more and more website using
