Re: Single Established Connection
You said you found this in Command Prompt but you mention a PID. Are you referring to a running process, or an established connection you discovered through netstat or something?
If it's a process I'd start by trying to find the file path to see if it's located somewhere familiar such as program files. If you have Windows 7, open task manager and from the "View" menu, select Columns > Image Path
If it's a tcp connection then use netstat to find the outside ip address and possibly what process on your PC is making the connection. That could help determine if it's something to be worried about.
And of course you could always do a malwarebytes scan.
