I tried Geswall freeware and currently trying professional. A Sandbox would be ideal for my wife, who spends a lot of time on foreign sites that sometimes have issues with malware, and I would not mind surfing in one myself. The good. Geswall does not slow surfing at all, and is the only sandbox I have tried that does not, and I have tried several. Sandboxie, I like, but slows browsing a second or two, which gets annoying after a while. Greenborder was great for speed but corrupted links and thus unusable. Several others slowed browsing considerably. The bad, Geswall logs essentially every internet site you visit, every file, etc and apparently saves this info for years. This is more intrusive than any spyware I have seen. I was going to get the pro version, til I saw the logging. What were they smoking? Is there not any way to disable this? wtf with all the firewall, etc needing to log everything. If it can be turned off, fine, if not, I have no need for spyware.
