Yeah TeamViewer, and thats no surprise.
I had an issue where I was using teamviewer to edit a friends INI file for Americas Army (the game) he needed a custom
resolution, well we get done and we exit TV and I made some changes too so we rebooted and gamed for a couple hours.
I get ready for bed and Windows alerts, I walk into the next room and TeamViewer had launched all by itself. I have never used it again.
I reported it to TeamViewer the next morning and they basically called me a liar.
This was about 2 to 3 months before all the security issues were discovered a couple years ago .
Yeah I steer clear of TeamViewer
