The biggest scams and PC attacks exposed

There are huge security risks associated with all aspects of technology, whether you browse the web, social network or even use a mobile phone. We've rounded up the 17 biggest threats and shown you how to fix them too.

Browsing the web via a PC or mobile phone isn't without its security risks. In fact, they're growing, day-by-day. 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.

But for every potential pitfall that malware hunters expose and neutralise, there seem to be five more waiting for a careless PC user to plummet into. Your job is to anticipate and evade a vast array of cleverly devised booby traps meant to catch the unwary.

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.

Why you should care: Online stores may take advantage of you.

Scenario: If it seems that five minutes after you searched for an item at an online shop, the price went up, that may not be a figment of your imagination. Prices at big online retailers like Amazon fluctuate almost hourly - based not only on supply and demand, but also on consumer interest level.

If a company determines that you have a strong interest in a particular product, it might hike the price by a few pounds to see whether you're still willing to bite.

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.
