I have Windows 8 Security Antivirus. I've decided to try the sandbox function while using Internet Explorer 10. I tried the BD Sandbox with Firefox without ANY PROBLEMS. When I opened IE 10 and clicked on the dagger, my computer crashed with the following message:"Page fault in nonpaged area avckf.sys". After my computer rebooted, Windows 8 Security did not recognize BitDefender AV. After rebooting three times, my computer is running smoothly. I downloaded BitdefenderSupportTool, ran it, and uploaded it to mediafire.com.
For the time being, I would advise not to use the BD Sandbox with IE 10.
