Though I can't help and am also looking for a solution, I started experiencing the same thing yesterday also with XP and IE. Upon startup the phising filter turn on/off window pops up and I don't know why. it has the added annoyance of somehow disabling my sound card when it does that so I have no sound. If I restore to a previous point my (which I've done a dozen painstaking times so far) sound comes back though when I use IE (I am a regular Firefox user but sometimes use IE) I lose my sound card again. Also, another pop-up appears that asks if I want to make IE my default browser, which it isn't now. These are all new symptoms that started with this pop-up.
Any help would be greatly appreciated as I'm now tearing my hair out.
