The current solution they are offering i feel is a false sense of security. Users on the forums continue to file complaints many are starting to look for other solutions. For those who use the Norton protection offered by comcast i thought this post would help you as time is running out. i don't feel that this was the best move for them but 20 million people will be looking for products and i guess that's business for Malwarebytes!!
