I think that Webshiled is interfering with the privacy settings of zonealarm pro. I have zonealarm pro latest version. AVast latest version. Windows XP SP2. If I enable webshield and use the Adblocking and cookie control( both in medium) of zonealarm then I can’t login to yahoo. It tell me that my browser is rejecting cookies. If I disable webshield then I can login. I test with two browser IE and firefox. I think the problem is the webshield
With ZAPro you need to disable cookie protection and ad blocking other wise a conflict is generated with avast. BTW you don’t really need these features on ZA.
