Whether its network worms, phishing emails, drive-by downloads or data sniffed from an open wireless network - we're all at risk. To use a computer safely in the 21st century, you have to be prepared to combat a growing number of constantly evolving security threats.

We've addressed the 17 top security threats that you might not be aware of, together with advice on how to defeat them.. The internet's smash-and-grab practitioners and con artists make a living off victims who fail to recognise the tricks of their trade.

The Fix: If you're smart, and refuse to pay more than what you consider a reasonable price, check out the free Amazon PriceWatch tool, an IE or Firefox plug-in that monitors a particular item, and alerts you when the price for that item falls below the threshold amount you set.
