You'd be surprised just how many different threats exist across the Internet. Malware and viruses lurk in everything from advertisements to email attachments, from app downloads to YouTube videos even. Flash in particular is really vulnerable to problems like that.

But one of the worst threats? Typosquatters. If you're the kind of person who never directly clicks on links, then you've probably typed your share of URLs into your browser bar. Unfortunately, malicious people are starting to take advantage of this and filling these mistyped domain names with malware.

Nearly half of all domain names use the .com extension, but there's another domain name that's really similar to it: the .om extension for the country of Oman. Can you imagine how many people accidentally type .om when they mean .com? A lot more than you think.

These malicious people have taken popular domain names (e.g. netflix.com, reddit.com, gmail.com), registered their typo equivalents, and filled them with profitable Flash-exploiting malware. View the full list of shady domains now.

Other popular typosquatting practices include shifting the "C" over (googlec.om), substituting adjacent keys (googlw.com), and doubling up on letters (googgle.com).

So the next time you manually type a URL into your browser bar, double-check and triple-check to make sure that it's the domain name you intended to type. Also, take extra precaution by installing an Internet security suite and learning to catch identity theft.

Do you type URLs manually? How often do you typo on them? Have you ever gotten malware from this? Share with us in the comments!
