Does anyone else use this programme? Its a software that supposedly prevents malware from modifying your files, thus preventing zero-day attacks. While I admit that it is very useful, alerting me to various threats that needs to be addressed(including using Hijack this for the first time in my life), it simply doesn't differ between legitimate use and an attack.............

So, what's your opinion on it? A keeper? Or ditch it in favour of just using a firewall like sysgate and zonealarm>
