http://support.microsoft.com/kb/969707 Service Pack 2 (SP2) for Windows Vista and for Windows Server 2008 contains many security, reliability, and feature updates. But MS now warns that this Service Pack has been found to have compatibility problems with 11 apps (up to now), mainly security utilities. These apps may not start, not run or have loss of functionality. Other apps may also experience problems. MS advises that if an app that is not mentioned in the table has a change in functionality after installing SP2 for Vista, the user should perform the following actions: • Restart the computer at least one time. This may correct the problem. • Contact the software vendor. There may be a newer version of the program that was released after SP2. • Report the problem to the software vendor and request an updated version. Here is the list so far of apps with compatibility problems. It is amusing that MS software is amongst them. Arcsoft Totalmedia v.220.127.116.11 Avira AntiVir v.8 Dr.eye Pro Trad_Chinese v.8.1 Eusing Free Registry Cleaner v.2 Holodeck Enterprise Edition v.2.8.0 Lenovo System Update Mac OS X by Vista OS X Microsoft Application Virtualization v.4 PC Tools Spyware Doctor v.5.5.0 Trend Micro Internet Security & Virus Buster v.2008 WebRoot Spy Sweeper v.18.104.22.1684 Good old Microsoft remains true to its tradition. If you ever hear that MS has made a product that doesn’t suck, you can bet your shirt it’s a vacuum cleaner. The list also includes Avira AntiVir 8. As AntiVir is recommended in TS 8-Steps for Removal of Malware, it may be in order to amend Step 1 to advise Vista users to install the new AntiVir version 9.
