That is a problem with the Shockwave Flash plugin (NPSWF32_12_0_0_43.dll)

You can check for problems with current Shockwave Flash plugin versions and try this:

• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

Also make sure to update your Norton software to the latest version (check for updates until it tells that none are available).
EDIT: the crashes with the Norton software are from last year, so you can probably ignore them.
