I've been scanning posts here and posting myself for over a month, and nothing has worked to "fix" my immunization problem with Firefox and Mozilla. Everything else immunizes completely.
I'm running Windows XP SP2, AVG, Firefox 3.0.1, and Spybot 1.6.0.30.
I've also installed Spybot 1.6.0.30 on my laptop, which is running Vista and the same combination as above and Spybot works flawlessly (I have not had to apply any "fixes").
I think the problem is an incomplete uninstall of a previous version of Spybot, possibly coupled with an incomplete uninstall of TrendMicro. I've downloaded and run the small Spybot .reg program and it had no impact on my results. When I examine "add or remove programs", there are no traces of TrendMicro.
I'll continue to scan this site, but meanwhile I'm installing Spyware Blaster to help me where Spybot can't.
As always, thanks for any help.
