    Spam isn’t just harmless marketing. It can carry malicious software that can hijack your computer.

    Try our miracle sex pill! Lose 30 pounds with this no-risk diet! Almost daily we’re inundated with spam emails, touting everything from hot dates to how-to-be-a-millionaire scams.

    It’s easy to laugh these emails off as harmless, if not annoying, marketing ploys. Yet spam is actually a huge industry and poses a serious threat to our safety online. What’s more, even if you never open a spam email or click on a flashy banner ad, the danger is still there.

    Spam emails often contain viruses and other malware (malicious software) that can infect your computer. In fact, the amount of malware spread via spam is staggering.

    Companies that produce antivirus solutions claim that they deal with some 82,000 new variants of malware through spam emails every day. During the first quarter of 2013 alone, McAfee, one of the world’s leading computer security companies, discovered some 14 million new malware viruses.

    Even worse, malicious software imbedded in spam can turn a computer into a hired gun for cybercrime. Fake ads for Viagra or penis enlargement pills are often set by criminals to snare a computer user, whose hardware is essentially hijacked and added to a sophisticated network of other hijacked computers called a botnet.

    A botnet can then be hired out to cybercriminals to perform distributed denial of service (DDoS) attacks. During a DDoS attack, a website is bombarded with so much data that it becomes unavailable to users.

    Such attacks are often performed as part of an extortion scheme, in which a site or group of sites are kept offline until its owner pays a ransom.

    Sometimes DDoS attacks are even directed at governments, and the consequences can be dire.

    In 2008, the Estonian government was the target of a massive DDoS attack, and most government websites were down for days. Many of the country’s online banking services went briefly offline, and the national network used for medical emergencies was likewise disrupted.
