I recently installed AVG on the family computer and ran a virus scan, which came up with a few problems. The biggest one was that the computer was infected with the XTreme RAT trojan. This has been removed, but looking at the capabilities a RAT gives I would like to see what damage has been done.

What do I need to be looking for in the Events Viewer for things like the Webcam being turned off and on, remote access, files being remotely accessed etc?

Do I need to take any further action to protect the computer in the future? I don't know how long it's been on there, my sons keep installing games and things from the internet despite me telling them not to, so I don't know where it's come from.

Any help/advice would be appreciated.
