Microsoft’s Windows 7 OS is five times more secure than the aging Windows XP operating system, the company has reported.
According to a threat report released by the software giant, the Windows 7 malware infection rate has risen by more than 30 percent in the second half 2010.
The company said that in the second half of 2010, the 32 bit edition of Windows 7 had an average infection rate of 4 PCs per 1,000. Meanwhile, the infection rate of 64-bit edition was at 2.5 PCs per 1,000 during 2010.
Microsoft derived the average infection rate for each of its platform by consolidating the data gathered by its Malicious Software Removal Tool (MSRT).
Windows XP Service Pack 3 had an average malware infection rate of 15.9 PCs per thousand, five times that of Windows 7.
Microsoft acknowledged that although there was rise in malware for Windows 7, the platform was far more secure than Windows XP and Vista.
“We're still seeing a decrease [in infection rates] for the newer operating systems," said Jeff Williams, the principal group program manager with the Microsoft Malware Protection Center (MMPC) .
"And with the broader adoption of Windows 7, more customers are protected."
Although there is no reason not to believe Microsoft's numbers, the company does have a vested interest in convincing customers to upgrade from Windows XP to Windows 7.
