NAV 2011 and Geswall 2.9.1

Hello guys. I had quite a hang of Norton autoprotect while trying to delete a part of a downloaded file through a Sandboxed Chrome - CPU constant 30-40% until Norton services are stopped or the PC restarted. So I took off Sandboxie for now. Does anyone have any experience using both NAV 2011 and Geswall? I like Geswall very much and have been using it quite a lot with other AV solutions.
