ActiveX controls

I have IE6.0 with Security controls on Internet set to Medium. Since ActiveX
files can be corrupted, hijacked, and be reconfigured to disclose so much
personal data, how can you maintain a secure system?


1] Why isn't this level sufficient to allow Active X, or do I have to lower
Security settings to Low on trusted Sites?
2] Do I have to change my Zone Alarm firewall settings too?
3] At the McAfee site, for example, you need to allow ActiveX settings. I
have done this, but apparently my computer doesn't recognize the change. Is
there some change necessay in the Control Panel?
Help please.
