Your developer has not acknowledged my email of about a week ago and Micosoft's forum moderators have not acknowledged my post of about two weeks ago. So, I am giving you friends and neighbors a try. Around November of last year I installed this product to replace SpywareBlaster, which quit updating to where it provided full protection and did not appear to have attentive support. After using S&D periodically, my Windows 7 64-Bit system, which unfortunately I have to keep running, experienced at least three BS'sOD. My security programs did not pick up anything unusual; but I suspect that S&D did registry damage. Without responses to the Microsoft posting or from your company, I do not know what to do next. Since I have made regular Registry Backups, my first inclination was to export one of them. Thank you in advance.
