Secure your browser.

I'm going to recommend that you do even better and follow Taskmage's fourth bit of advice for your browser. Yes, firefox with NoScript and ABP and such is great, but you can do even better.

The most secure option is to have your browser completely separate from any vital information on your PC. The easiest ways to do this, in order, are A: Second computer, B: live CD, C: Virtual Machine/Browser Applicance, D: Dual boot.

Technically, the last three (and some setups of A) CAN still get access to your main system, but it's much harder, and extremely unlikely.

A- This is the easiest, but also the most expensive. Just buy another computer and use that for web browsing, email, and other things that are very insecure. All the better if you put something like Ubuntu on it.

B- Find a LiveCD, and boot off it whenever you want to search the web. I recommend something like DamnSmallLinux, which is made for the task, and which can be easily customized (for example, to add your custom bookmarks); although it won't work very well in all computers. Ubuntu will be much more fool proof and easier to use, but it's LiveCDs are more inclined towards installation than daily use, so they're pretty slow.

C- Browser Appliance is a virtual machine built to run firefox. Won't need to worry about rebooting your computer, although it will of course be slower than a regular browser.

D- Basically like B, except you install it instead of using a CD. Quicker, and still very easy to set up, but not as foolproof as the other options.
