I installed SB 3.5.1 (with 6/29/06 definitions update(s)) with SpySweeper 4.5.9 (Build 709) already installed. When I clicked to "Enable" the definition file, two or three SpySweeper windows appeared (at different times) each saying that for a particular spyware file that affects InternetExplorer, SpywareBlaster changed the settings -- and do want to accept the changes to the settings. Hence, I am wondering whether the two progs. function at full effectiveness with SB having its settings prevail over SpySweepers, or is the latter the more advanced in its spyware preventive measures. Thanks.
