Never click on a link in an email unless you a) expected it. b) it comes from someone you know. c) Your email program allows you to see the actual link, not the text for it (which can look like a link) - if your email program doesn't allow that, use one that does and d) is a link you want to go to.
For example, a link claiming that your PayPal account will be closed if you don't respond within 24 hours - with the actual link going to http://www.paypal.scam.com, or one from a bank you have no account with (so you have no account with them, how can going to their site hurt you? It can - that site can grab information from other pages you have open - like your real on-line banking page.)
Don't download files unless you know the source. If you're even a little bit unsure, no matter how much you want the file, don't download it. *N*E*V*E*R* use peer-to-peer (torrent) programs to download files, unless they're from the manufacturer. (Blizzard, for instance, uses torrent protocol to update users.)
Don't go to questionable web sites. Use Firefox as your web browser. Add the WOT add-on. Listen to it.
Learn enough that you don't have to take anyone's word (not even mine) for how to stay safe on the internet.
I've been on the internet since the 80s and have NEVER downloaded ANY malware, nor had a computer infected in any way. Or used any anti-anything program to protect any computer of mine.
