Hello, I have the legal program WinZip 10 on my computer. When I run it, it displays a window: there is an important update. I downloaded the update and tried to install, but ZonaAlarm said: Winzip 10 is a malicious program, and prevented the installation. Do you have any hint, what is going on?

Operating System:Windows XP Pro
Product Name:ZoneAlarm Pro
Software Version:7.0
