Upgraded my system from XP SP1 to XP SP2 on two computers. On the one computer, after updating to SP2 and installing all recommended Microsoft critical updates for SP2, Spywareblaster started experiencing malfunctions.When I double click on the Spywareblaster icon to call up the program a window pops up indicating that Windows Installer is preparing to install. A second issue that came up on the same computer is that Sun Java, despite having the most recent version installed showed an icon in the system tray indicating that Sun Java was downloading updates. I managed to resolve the Sun Java issue by shutting down the option within the program to check for updates. I have been reluctant to uninstall and reinstall Spywareblaster because I understand that all the protections within Spywareblaster should first be disabled before uninstalling Spywareblaster. On the second computer there were no adverse issues to Spywareblaster or Sun Java created after installing SP2. Any thoughts or recommendations appreciated.
