How did the Backdoor.Teamviewer get on my computer?

This Trojan is currently being detected as Trojan.Teamspy, Gen:Variant.Mikey,, , and Backdoor.TeamViewer by various antivirus programs. It has been thought that this malware may be one of the vectors for the many TeamViewer hacks that have been reported in May & June of 2016. Therefore, it is important to make sure your computer is running a good antivirus program with updated security definitions. Unfortunately, the only clues that would indicate you are infected with this Trojan is if you notice the %AppData%\Sin\5s.exe application running on your computer or if they take control of it while you are watching. This allows them to view your documents, pictures, and run other programs that steal passwords to your online accounts.

While connected they will be able to use the computer as if they were in front of it. Once the attackers have the victim's IP address, they are able to connect remotely to the victim's computer and take remote control of it.
