Hi there, Tried to disable protection before uninstalling Spywareblaster 4.1 ,to allow me to install 4.2 but received access violation error:- Error: Access violation at 00x771544F1(tried to read from 0x2E2E2E2A), program terminated. (only disables 422 items in restricted sites / disables all protection in IE /but doesn't get as far as disabling any Firefox protection) No issues enabling all protection again. Thought this might be due to Spybot S&D so disabled its protection and tried again,still same problem. Also tried to disable Windows Defender too,same. I don't think I can just overwrite 4.1 with 4.2 install and don't know what issues just unistalling 4.1 without disabling protection will do. Would like to update Spywareblaster so any solutions kindly accepted.
