Hi

I've been using Spywareguard and Spywareblaster along with Adaware SE and Spybot S & D for quite some time now, and have not had any conflicts with any of them.Spywareblaster works silently in the background thing to remember is to get updates often....

I have Registry Mechanic Pro 5, and am really not that impressed with the registry cleaning options, very seldom use it anymore as I find WinXp does a good job of keeping the Registry structure secure.(unlike Win 98).

For "cleaning" (hate that word really) I use CCleaner, is simple and allows for restoration of cleaned entries.

For the registry I use NTREGOPT useful for compacting the registry..

I like the Windows Defender, liked the MSAS Beta moreso...but hey it's free....

Just remember, whatever you decide is best for you, beware of fakes......Rogue Antispyware Programs
