I have just installed the latest version of ZA Internet Security Suite in my laptop. But I got this message on my ZA anti-virus, " anti-virus scanning is de-activated. This can occur if the system clock is set forward or the anti-virus updates are diabled." then a link is supplied ," click here to update now and re-activate scanning".
I click on it and it prompt me that antivirus is not able to activate.
I am using Windows Vista SP1. Please help. Thanks.

Operating System:Windows Vista Home Premium
Software Version:6.1
Product Name:ZoneAlarm Internet Security Suite
