BufferZone Security Pro lets you download and run files from any website and open any email attachment with complete safety. Unlike anti-virus and anti-spyware software, BufferZone requires no signature updates, while protecting your PC against spyware, viruses and adware--even new and yet unknown ones. BufferZone ''automagically'' protects you against vulnerabilities from all sources: external media, P2P, IM, Web browsing and email.
