If you get the error code M7357-1003 on your computer, it typically points to a component on your browser that needs to be updated or that is being blocked by a security setting or program on your computer. Follow the troubleshooting steps below to resolve the issue.

i actually followed all the steps, but when it came to the last one which had to do with "do you have anti-virus installed?"  i don't know how to resolve this other than disabling my avg.  

Sometimes anti-virus software such as Webroot, Kaspersky, Immunet, or Intego VirusBarrier can interfere with the player Netflix uses to play movies and TV shows.

• Disable your anti-virus software and play your movie or TV show again.
• If a movie or TV show resumes after disabling your anti-virus software, this may indicate that the software could be outdated or unintentionally preventing the Netflix service from playing.

If you continue to see the error, there may be additional configuration settings within your browser settings preventing you from watching a movie or TV show. While trying to watch from a different browser you may not see these specific configuration issues. Please reach out to your anti-virus software manufacturer or a trusted IT professional for assistance with these issues.

so, needless to say, as i have just installed and updated the latest version of avg, how could it possibly be out of date?  the next issue was to disable avg, 

it was working fine until i installed AVG!
