Thanks for your quick response. I am looking for the SBFWIM.sys, but am not able to locate it with either uninstall scheme. I am still working on it, but I haven't used VIPRE since my last BSOD situation and MSE has been working like a charm. I have no idea how any of VIPRE is in my system, as I completely removed it 3 months ago. It happens that my VAIO notebook, VPCSA43FX had all sorts of issues with Norton 360 and VIPRE, and we removed all from the system prior to installing MSE, as you suggested. This VIPRE issue now is very strange to me! By the way, VIPRE is very stable at my company on desktops, but I am considering changing to MSE throughout my company network. Will let you know what I find with SBFWIM.sys.
