This is a legitimate site used for remote-access purposes, HOWEVER
these services are often used by phone con-artists to hack into the unwary user's machine and steal account passwords, etc.

Useful program that has a free and pro version. Kind of like video chatting, except instead of using your webcam, you use your screen, and only one person can present their screen at once. Supports up to 250 users in one chat room. Free version will suffice for most tasks. You can allow other users to control your screen, but only with your permission. Safe software, no virus.
BTW, below a person comments this is Windows only. I have seen this work for Windows, Mac, and Android.
