Hi, smoggy. to 'the gang'..!
Linux is definitely a good choice for an older netbook like yours. I can understand your thinking behind wanting to go for Lubuntu, since it's the lightweight variant of Ubuntu.
There's also the issue of drivers. In Linux, it isn't an issue.....98% of device drivers are built-in to the Linux kernel by default. In Windows, you've got to update all your drivers individually, by hunting them up on their respective websites. In Linux, you update the kernel. Job done! ALL drivers updated at the same time.
And malware, while not 'non-existent', is so rare as to be extremely unusual. That's why AV is not really needed, unless you're running something like an e-mail server, and you want to stop Windows users from passing crap onto other Windows users. Reputations in the Linux ecosphere can be made (or broken) over an issue like this.
ALL LInux distros have strong firewalls built-in as standard; as stated, they usually just need to be activated.
Do be aware that there are alternatives to the 'buntu-based distros; many people think these are the only ones there are, they're so heavily advertised, and mentioned everywhere you look on the Web. If you really want something lightweight, you could do worse than try what I run myself (and what Al has mentioned).....'Puppy' Linux. It's a tiny little thing; typically around 200-250 MB in size. It loads into, and runs entirely from RAM (the fastest part of any machine by an order of magnitude).....and, best of all, you don't even have to install it to your hard drive if you don't want to. You can run it from what's called a 'multi-session' DVD; the changes from each session are 'written' back to the DVD at the end of the session. Or, you can install it to, and run it entirely from, a flash drive. Puppy will ask if you want to create what's called a 'save-file' at the end of the first session. This will hold all your changes, alterations,and customizations, every time you shut down.
It sounds complicated, I know, but trust me.....it's very easy to get the hang of, really..!
Al has written a tutorial on how to install Puppy:-
....although this is written more from the point of someone wanting to dual-boot, who has already got a Linux distro installed, and which uses the GRUB2 bootloader.
Here's a good tutorial for installing the current Puppy 'Tahrpup' to a flash drive (if you're interested):-
Just a couple of suggestions. Anything you may want to know.....just ask. That's what we're here for!
