I have twice been invaded by System Tools 2011 despite a current and active copy of Zone Alarm Extreme security on my PC, so my question is twofold:
a) why didn't zone alarm protect me? and
b) if it can't protect me why should I pay for Zone Alarm when it would be cheaper and easier to pay the extortionate malware and save myself tech support fees and useless security services?

Suggestions on how to prevent future rapes would be appreciated.
