If you have the correct, up to date protection in the first place, there should be little cause for concern over web nasties, but you do still have to exercise common sense, and a degree of caution. Never download anything from an unexpected pop up, and only download from legitimate, reputable sources. If you choose to download from P2P networks, as many of us do, you should always scan everything you download for viruses, trojans and spyware. If you treat everything on P2P as hostile, until proven safe, you won't go far wrong. Oh, and never open unexpected e-mail attachments, even if they appear to be from someone you know.
