I was wondering what this topic was about as it seemed unrelated to the avast! Mobile Security and this appears to be about the avast software updater in the avast desktop antivirus.

If so hopfully one of the moderators can move this to the avast! Free/Pro/Suite forum, http://forum.avast.com/index.php?board=2.0.

The bigger question is do you actually need JAVA as it is a huge target for malware. If you don’t have an application that requires JAVA (not JavaScript) or a site that you most visit uses JAVA, then your best option is to uninstall JAVA.
