Strange that it was able to get and update both your JAVA 6 versions. You should just have the latest JAVA versions. Ideally unless you actually have applications and or websites that you have to visit and they use JAVA (not JavaScript), then you should simply uninstall JAVA.
Strange indeed! I suppose it is just a current bug as I see that a few people are having various issues with Software Updater. Guess I’ll just have to wait until the next Avast 8 update.
