Eliminate (uninstall) older java versions. Install only the latest Java. You can use JavaRa to help you in the task.
The same with adobe FLASH (for IE, even if you use other browser). For flash, I would suggest first uninstalling any and all versions, clean any remnants (like for example, by uninstalling with the help of Revo Uninstaller and then with CCleaner) and then install the latest stable version of flash for IE.
Please report back.
