Spywareblaster in XP

Well, I'm not Javacool, (or any kind of "cool" for that matter ), but SpywareBlaster sets the "kill bits" for the ActiveX controls it targets in a shared section of the Windows registry, not in a user specific area. So, running it from an Admin account would set these flags and cover all users on the system from that point forward. (Don't forget to run SpywareBlaster periodically to check for new updates. Once a week is probably fine.)

I say to run it from an Admin account just because I believe people should only install programs and make global security / system configuration changes from an Admin account - just to be sure that the program you are using has the necessary access it needs to do a clean and complete job. I don't know whether the rights needed to set these kill bits are available from the limited accounts or not.

Edit: Actually, it occurs to me that I was speaking above only about the primary purpose of SpywareBlaster - the ActiveX kills bit settings. However, this program has some other protections now that may or may not be user specific. It looks like the Cookie protection is stored in a user specific registry key. So, we'll need Javacool to tell us if the program therefore has to run per-user for that protection to work...
