After installing AVG’s new 2011 version of their anti-virus software, you might find issues uploading Youtube videos, logging into Webkinz, and even other web based services that make use of Java. I created a video that walks you through step by step how to allow these things to work. Video can be found at http://www.youtube.com/watch?v=SK6NlirwfnA or just watch it below. It walks you through disabling the Surf Shield which is the main source of the problem. I would recommend disabling it when you need to and the re-enabling it afterwards to make sure you stay fully protected. Eventually AVG will fix this issue with another update.
