Why should I start a new thread about the same problem as for example bob3160 is having ? What more details do you need ? When I start my system the behavior shield is not on. I´m running windows 7 home premium with Avast pro antivirus. There are several different posts of this problem before, but this was the newest one so I thought it would be appropriate to post it here ! Sorry to upset you, but I thought this was a forum for help and answers.
