I’ve been using Sandboxie for a long while to run all those questionable downloads on Windows. It’s a great light weight sandbox (as the name implies) for running random downloads, or even going to questionable websites as Sandboxie does a great job of isolating processes, and their filesystem access.
It’s not been all that cheap, but I felt it was worth it. I went to check to see how much it is as the conversation had come up on discord, and it turns out that Sophos had bought Sandboxie, and opened up the source code!
The downside is that there will be no further official development of the product. So I guess at some point I’ll have to break down and get a signing cert and re-build it if I want to keep using it.
Last version is locally mirrored here, as I understand it’ll be deleted soon enough.
