Although most people seem to think of Vista as being one of the worst mistakes that Microsoft has ever made, I have never made a secret of the fact that I prefer Vista over XP. My main reason for this is that Vista is a lot less suseptible to malware infections than XP is. I have lost count of the number of times that I have had to manually disinfect a particularly nasty malware infection on a Windows XP machine for friends, family, and clients. I’m not going to say that Vista is immune to malware infections, but to date, nobody has ever asked me to help them to disinfect their Vista machine. I know that the nay sayers will probably say that this is because more people run XP than Vista, but there is finally some hard data to back up what I have been saying all along.
The article at: http://blogs.pcmag.com/securitywatch/2009/04/malware_on_vista_rare_accordin.php shows the number of infections per 1000 machines that are running various operating systems. The rate of infection is far lower for Vista than it is for XP.
