Security firm BitDefender took 385 of the most popular malware samples it found in the past six months and threw them at Windows 8 to see how it fares in its default state, with Windows Defender enabled.
61 malware threats managed to infect Windows 8, or about 15.84 percent!
"As a means of protecting a computer from viruses, data theft and other type of malware, Windows Defender is better than nothing," said Bitdefender Chief Security Strategist Catalin Cosoi. "But it's not a whole lot better. Most of the popular antivirus can do better. The conclusion is clear: Using your PC without a security solution is extremely risky."
