Spyware?

[WaffleBoy]

Hello,
When I am on my log-in screen on my computer, I sometimes get this message: "Do you want to shut down the computer while others are using it? They may lose data" (Or something like that)

Do I have some kind of spyware on my computer, like Trojan or something?

And how do I check if I have it? My Antivirus program (AVG 2013) does not find any threats.

Are you on a home network? Do you have network shares that others connect to?

If you have a network share, where other PC's are connected to it, you will get that message.

it sounds as if someone is remoted-into your computer via a Remote Desktop Connection; It is not a virus.

Good to hear that it is not a virus
But I do not share network, and I have never used RDC...

Do you have a phone connected or other devices?

Do you have more than one user account on your computer?

The next time that you see this happen: Go into Task Manager and you'll see a tab titled "Users" and that will let you know what other user is currently logged-into your computer.
