What is suspicious OUTBOUND traffic?

I keep getting security alerts from Norton saying that it has detected "suspicious outbound traffic" and would I like to run Power Eraser. Several things stopped working after I ran Power Eraser so I undid it. My question is, What is suspicious OUTBOUND traffic? Is my computer sending some kind of information to another computer even when I am not using it? I have a laptop and even when the lid is closed, the fan frequently runs for long periods--I get tired of listening to it and have to pop the battery and pull the power cord to get it to stop. Is my computer sending data while it sleeps? What could it possibly be sending that is "outbound traffic"?

Re: What is suspicious OUTBOUND traffic?

@squidbrain9 Please provide a screen shot of what you are seeing. You can use the built in "Snipping Tool" if you are on a Windows device. How to post images to the forums is explained here: https://community.norton.com/en/forums/how-post-image-forums-0 

Outbound traffic can indicated a lot of things, in your case you have something running that is taking system resources for your fan to be running loudly AND while the laptop is sleeping. In addition to running Norton Power Eraser you also can download and run Malwarebytes alongside of your antivirus product. Get it here: https://www.malwarebytes.com/

Re: What is suspicious OUTBOUND traffic?

Outbound traffic is something on your computer that is connecting out to the internet.  If suspicious, it could be malware communicating with its command and control center.  If you are seeing a lot of internet activity when you are not really doing anything with your PC, it is possible that your computer is compromised and being used as part of a botnet for things like conducting DDOS attacks.  You definitely want to investigate what those Norton alerts are all about.

Re: What is suspicious OUTBOUND traffic?

Not sure about the traffic issue, but for your battery, do you have Windows 10 with included Cortana? I've been reading about issues with fans running continually or too much, and it seems a common problem is with CORTANA. If you have windows 10 and don't use Cortana, find the program folder where its installed. There should be 2 folders and one in particular has all the dll files. Rename the [Cortana Core.dll ] to something like Cortana Core.dllx and Cortana won't run and as a consequence, your fan won't run near as much, especially when laptop is sleep mode. I'm not familiar with using Cortana myself and didn't know if its included with Windows 8/8.1 or not. I use Windows 7 myself.

@squidbrain9 You can view and isolate the offending process using this handy tool I use frequently. Run it from your desktop and look for processes that don't make sense. IE process names in all CAPs , etc.  https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview

You may also want to run Malwarebytes as I previously suggested to check for and remove offending programs.
