As you'll see from the screen shot, that's not the case in Windows 7.

Windows 7 is still in beta and ThreatFire also doesn't officially support this OS (yet). So i see no problem. That feature works fine in XP and Vista.
it's behavior blocker
For instance... what?
Which is suspicious for it?
Um, malware? I thought you understand the concept of behavior analyzers and blockers.
Behavior blockers track what every program does and if they detect behavior that is common for malware, they prevent it, rollback the changes and alert the user. So if something tries to add itself into system folder, add system entry, starts listening to specific ports and tries contacting IRC server, behavior blocker will most probably jump on it.
The good is that behavior blockers are basically immune to packers and crypters and provide excellent 0-day protection without regular updates. The only downside is that they aren't exactly effective against Fake AV's where you just need signature detection.
