Adobe has announced that it will be making security updates available on a regular schedule. Adobe’s Reader and Acrobat products have been in the firing line in recent months with hackers targeting vulnerabilities in their code with the aim of infecting innocent users computers. The company will issue vulnerability fixes on the second Tuesday of every third month. This is a timely move by Adobe, which is similar to Microsofts similar initiative to Microsoft (which releases security patches on a similar date each month)”]
