Less like the key, really, than a car - browsers provide the means for traveling around the Internet to interesting destinations. Unfortunately, sometimes uninvited passengers climb in. On rare occasions, they even 'carjack' you.
So, what can you do to stop them?
There are a number of options, the first of which is the browser software you choose to use. Microsoft's Internet Explorer still has the lion's share of the market, but it's losing ground to other, more secure browsers such as Firefox.
Even if they're not actually more secure, these other browsers are not as likely to be targeted simply because the people who attack them prefer to go where they'll get the biggest bang for the buck. Until laws change and software vendors get more serious about the security of their products, the best way to avoid being targeted is to lay low.
Education is another key to 'hardening' browser security.
There are a lot of options and setting in Internet Explorer (and most other browsers) that allow you to have more control over what is allowed and what isn't. The trouble is, most people have little to no idea how to set them properly.
For example, should you disable Javascript, leave it enabled or set it up to prompt you every time a website uses it? In this particular example, it depends on your tolerance for annoyance. If you disable it entirely, some websites just won't work. And if you set it to prompt you, you may get a lot of messages popping up if you frequent sites that use it.
It's an undesirable trade-off to be faced with, and one which we can hope someday won't be necessary. But in the interim, it isn't necessary to be a computer geek to experiment and read a bit to find out what these settings affect. The first time you're infected and lose a day recovering, you'll wish you'd spent the two hours finding out.
Another important factor here is how you use your browser. If a warning message pops up when you're on a website, do you just click OK and move on or do you actually read it? Unless you know for a fact that you can trust the site, it's always best to be thorough.
Most users are unaware of the extent to which using a browser opens up their system to the rest of the world. Being on the Internet means not just seeing, but being visible. And accessing sites usually means being accessible. It isn't just harmless cookies that can be downloaded to your system. Once executable programs are downloaded they often have free rein to your entire system.
Back to education for a moment. Spend some time learning how to lock down your system, outside the browser settings, to make it more difficult for these errant programs to gain Administrator level privileges. Your time will be well re-paid.
