Detected Outbound Traffic

Hi 

I keep getting a message box pop up with ' 0utbound traffic detected' and message about a large amount of traffic going out from my laptop.

It then asks the question 'do you want to run Norton Power Eraser' When I answer yes it starts to look through the files then stops and comes up with the message 'An error has occurred, Unspecified error, Error code 0x80004005,n5,nC0.

Whats the answer to this -How do I stop Outbound traffic -or check where it is going to? Also how can I make Norton Power Eraser work? 

I have seen questions on this before -but no satisfactory simple answer on how to fix it.

Re: Detected Outbound Traffic

The TCPview program will show you active connections and where traffic is going.  You can do "whois" to see who's receiving the data.  It's a free program.  I'm no expert but I use it often to try to figure out what's going on.  Good luck.

 Hi Help me Rhonda:

Norton's Intrusion Prevention System (IPS) works with the Norton Smart Firewall to monitors traffic entering and leaving your computer.  Some types of malware and PUPS (e.g., potentially unwanted programs like browser toolbars and adware) will try to collection data from your computer and "phone home" to upload the data to a remote server, and Norton will display an "Outbound Traffic Detected" alert if it detects any outbound activity on your computer that seems suspicious.

On the other hand,  there have been instances in the past where a new set of IPS definitions incorrectly triggered these "Outbound Traffic Detected" alerts for "legitimate" outbound activity through the firewall (e.g., automatic updaters checking for software updates on the manufacturer's server) - see Symantec employee dong_chung's 2015 announcement IPS “Outbound Traffic Detected” Alert about a past problem with the IPS definitions.

Go to Security | History, search for "outbound" in your Recent History and then double-click on one of these "Outbound Traffic Detected" events to see if you can find any further details.  This might tell you the IP address of the remote server your computer is trying to connect to as well as other details about the alert.

I'd recommend against running the Norton Power Eraser (NPE) mentioned in your pop-up alerts. The home page at https://security.symantec.com/nbrt/npe.aspx?lcid=1033 warns that "Norton Power Eraser uses our most aggressive scanning technology to eliminate threats that traditional virus scanning doesn’t always detect, so you can get your PC back. Because Norton Power Eraser is an aggressive virus removal tool, it may mark a legitimate program for removal. However, you can always undo the results of a scan. It can also help detect and remove Potentially Unwanted Programs."  The NPE is prone to false positive detections and it is meant to be used as a rescue tool in emergency situations when your operating system becomes unstable or you have a persistent problem that cannot be fixed by a standard antivirus / anti-malware scan.

If a Norton Full System Scan doesn't find any threats on your computer I'd recommend using the free Malwarebytes v3.x (available at https://www.malwarebytes.com/free/) to run a second opinion scan.  After you install Malwarebytes just be sure to disable the 14-day trial of the Premium (real-time protection) features by going to Settings | My Account and clicking the Deactivate Premium Trial button as shown the support article How-To: Deactivate Trial Version in Malwarebytes 3.  Then run a Threat Scan to see if MB v3 can find any malware or PUPs that might have been missed by Norton.
