Hi I created a thread at Bufferzone forum because of a strange behaviour I'm encountering. I not received a response yet, but I resolved post it here too, since you guys can be aware of and can (if of interest) try to verify if is true. http://www.trustware.com/forum/viewtopic.php?f=2&t=3045 I installed yesterday Bufferzone Pro free in my machine. I noted a behavior and wanna confirm it: My current system is a Windows 7 Ultimate x86: I'm using a default Administrator account with UAC at max. I hardened it with built-in mechanisms: - Changed it to autologin through "netplwiz.exe" - Changed UAC local policies to "ask for credentials in the secure desktop", to not "detect application installations and automatically prompt for elevation" and to "only elevate executables that are signed and validated" (I tried to copy the behaviour of linux distros with option to autologin - When you wanna do something that require Administrator privileges, it ask for the Administrators password - sudo). Enabled Applocker to deny executions (to execute something you need right-click the executable and use "Run as Administrator" - Which ask for the Admin password). So the system behaviour is: 1 - When something try to run (through a drive-by or through "Double click") applocker deny it. 2 - When you use "Run as Administrator", if the file is signed, windows ask for the Admin password - If not signed (even with correct password), system return a error and deny execution. Now after install Bufferzone, when the executable is inside Buffezone, Applocker is being ignored. When I do a "double click" It detect the installation and automatically prompt for elevation and Admin password if the file is signed or already show the error message if not signed. The Bufferzone folder (C:\Virtual) is not in my whitelist rules. So what's going on? This is a Bug?
