Most people owning a PC are familiar with Microsoft’s patching process – it’s easy and it’s there. For a lot of them, it also gives the impression that Microsoft’s products are chock-full of flaws. But, according to Stefan Frei, Research Analyst Director with Secunia, it’s not the vulnerabilities in Microsoft’s products we should worry about, but those in third-party software. 55 percent of the end-point users have more than 66 programs from more than 22 vendors installed on their systems. Of the top 50 software used, 26 are developed by Microsoft, and the remaining 24 by 14 other vendors.
