64-bit Windows safer, claims Microsoft
Windows users running 64-bit versions of the operating system are less likely to get infected by attack code, Microsoft's security team said yesterday. But that doesn't mean they won't, countered an outside security researcher.
"64-bit Windows has some of the lowest reported malware infection rates in the first half of 2009," said Joe Faulhaber of the Microsoft Malware Protection Center in a post to the group's blog yesterday. "64-bit malware is still exceedingly rare in the wild."
Faulhaber cited statistics gleaned from Microsoft's Malicious Software Removal Tool (MSRC), a free malware detection and deletion utility the company updates and pushes to users monthly. According to Microsoft's data, the 64-bit version of Windows XP was 48% less likely to be infected than the 32-bit edition during the first half of 2009; PCs running Vista 64-bit, meanwhile, were 35% less likely to be infected than Vista 32-bit.
