Hold on to your virtual hat because the following might just blow it off. 

Mcafee's fourth annual "Mapping the Mal Web" report indicates that .COM, the web's most heavily trafficked top level domain, is now the riskiest - Fifty-six percent of all risky sites end in .COM. 

McAfee analyzed more than 27 million websites to uncover which domains are the most dangerous. While .COM is the riskiest top-level domain, the riskiest country domain is Vietnam (.VN). Japan’s .JP ranks as the safest country domain for the second year in a row. The report also found that 6.2 percent of the 27 million websites analyzed pose a security risk – up from 5.8 percent last year.

“This report underscores how quickly cybercriminals change tactics to lure in victims and avoid being caught,” said Paula Greve, director of web security research for McAfee Labs™. “Last year Vietnam’s .VN was a relatively safe domain, and this year it jumped to the third most dangerous domain. Cybercriminals target regions where registering sites is cheap and convenient and pose the least risk of being caught. A domain that’s safe one year can be dangerous the next.
