Team Viewer is a great tool, but at the same time it's the ultimate trojan horse if used the wrong way. And the best thing is that we install it ourselves and it's there in front of our eyes the whole time. It's very convinient to leave it constantly on, so just in case you need your PC when away, you can log-in and do your thing BUT what if...? I suppose the technology behind TW can allow anyone from the company severs to get into anyone of the users computers that have left TW on? Does the company/people behind TW has any history that will either make you trust them or the other way around?
