Sandboxie had worked fine for me with Firefox but had serious problems with IE. This BufferZone Security looks really great to me. I have an ExciteMail account that requires IE with security set low, after two pages worth of Sandboxie ExciteMail, it would begin to freeze the whole system. Last use of Sandboxie with ExciteMail resulted in AntiVir's Guard Umbrella closing, used GoBack and then uninstalled Sandboxie 2.60. Found this Trustware BufferZone from the report linked from the thread below titled Eight Sandboxes Reviewed. (<Link back is Thread, link ahead is the Report>) Eight Security Sandboxes Reviewed and Rated They have a "Single Application Edition" (like Internet Explorer) version for free and I just installed it. A click on the BufferZone.exe downloaded to desktop started an 8016KB download and installation. Used it once now to do all I wanted with ExciteMail on IE with absolutely no problems. Looks like an excellent protection for my needs. Search of Wilders for BufferZone showed nothing, website for BufferZone is: http://www.trustware.com/ would be interested in any comments on this Sandbox.
