McAfee's third annual report, looks at riskiest and safest domains across the globe. Cameroon, the small nation on west coast of Africa reached, top spot this year with 36.7% of its sites posing a security risk. Because .cm is often a typo for .com, McAfee said, cybercrooks like to use that domain to set up typo-squatted sites to hit you with malware. The generic and widely used .com domain itself isn't much safer, according to McAfee, jumping from ninth last year to second this year in riskiness, with 32.2% of its sites potentially hazardous to your PC's health. Romania (.ro) is tagged as riskiest domain for malicious downloads, with 21% of its sites delivering payloads of viruses, spyware, and adware. The information (.info) domain is seen by McAfee as the most "spammy," with 17.2% of its sites generating junk mail.
