Here is some good advice from the article for IE users:
Get into Tools/Internet Options/Security. Go to 'Custom Level' and disable 'Download unsigned ActiveX Controls' and 'Initialize and script ActiveX Controls not marked safe for scripting'; set 'Java permissions' to 'High Safety'; disable 'Meta Refresh'; disable 'Launching programs and files in an IFRAME'; set 'Software Channel permissions' to 'High Safety', disable 'Userdata persistence'; disable 'Active scripting', 'Allow paste operations via script', and 'scripting of Java applets'.
Accept session cookies but not stored cookies. Never use in-line auto-complete, and never allow Windows to save any of your passwords.
Now go to Tools/Internet Options/Advanced and clear 'Enable Profile Assistant', select 'Do not save encrypted pages to disk', clear 'Enable page hit counting', and select 'Empty Temporary Internet Files folder when browser is closed'.
Wine maketh merry: but money answereth all things.
--Ecclesiastes 10:19
