The latest version of Comodo is by no means glut-wear. And when it comes to security software the latest is almost always the best decision. Running something over 3 years old is foolish, and should never be recommended to someone; especially, when you have no info of the users knowledge.
Firefox 2 was awesome, should I rollback to avoid this glut-wear? My point is, what glut-wear are you talking about in regards to Comodo?
