Susan had a tech who put remote desktop software on her computer. Should that bother her? Leo says that in the end it comes down to trust. Does she trust that he won't do anything nefarious? And if he is doing nefarious things, then it's likely too late. If she's concerned, it's important that she ask the tech to spell out why he's putting it on and realize it's a matter of trust. Leo recommends asking the tech to remove it and use an invitation based remote system instead. There are plenty out there and many are free.
David works from home via VPN to the office. He's unable to view both screens from his office at his house. Leo says that he doesn't know of any VPN that allows for using multiple screens, and it could be a security issue.
