Windows Security Alert for netsession_win.exe

Question

My Windows Firewall blocked "netsession_win.exe" because it was accepting incoming network connections.

I have no clue what this program does. Should I allow the incoming connection?

BTW the publisher is Unknown.

Answer 1

It has been reported over the last couple of days, possible link to live video,
Possible that you have no firewall set on your router( possible),
enter in search - it has a uninstaller at this location,
C:\users\Your_User_Name\appdata\local\akamai\
I do not know if you should let it pass,
That would depend on what you would need it for, if at all.
Site that claims to be the source.
All information was from this site and it has much more detail,
It does not sound if it is highly dangerous type,
but you can never be to careful,
Hope this helps

Answer 2

It is reported to be harmless, but no one remembers ever authorizing the software to install. I myself uninstalled it and everything has been running fine since. I have been told that other people are using this software, bundled with some new virus, it's yet another exploit using someone's harmless software.

Answer 3

Scott Hanselman has a write up of this that can be found here. He explains how he found it and what he's found out about it.

Summary seems to be that it is signed by Akamai (CDN company) and probably bundled as part of Flash. What it does we don't know! It's official website is here.
