No. 01 - Storm Virus

Storm gets its name from the trap that is its method of infection.

Starting in early 2007, users began receiving emails with the subject line, "230 dead as storm batters Europe," and a link to the story.

Don't click! No! You've instead been led to an infected site, and you're now downloading the virus, like it or not.

The Storm headlines changed to suit the news, but the virus stayed just as dangerous, infecting as many as a million computers and recruiting them into its botnet.

What's more, Storm has gotten sneakier over time, sending out emails that appear to be from tech support saying to click on a link for a security upgrade (quite the contrary) or sending links to online porn or celebrity photos or even an ecard.

To this day, it remains a major security risk and continues to spread in new ways, including via links inserted into blog postings and bulletin boards. Watch out.
