I am considering running Prevx/SafeOnline with Avast! Pro Antivirus, which includes a sandbox feature. I know that Prevx/SO doesn't currently work with Sandboxie, but would it work with Avast's sandbox? I travel a lot and therefore frequently have to use my laptop in hotels with insecure internet connections, and I'm just concerned about my protection in that environment. Right now I'm running Avast! free with the Windows Vista Firewall along with Windows 7 Firewall control free and Sandboxie free. With an insecure internet connnection, what's my best option? Is a sandbox of some sort necessary? Thanks!
