What To Do

You need to check whether you are able to connect to Sophos Live Protection (Sophos cloud).
You can do this by downloading a purpose built tool which will check your connection, or you can check it from the command line.

1. Checking for the connection

To check the connection from the command line:
  1. Run the following command from a command prompt
    nslookup -type=TXT
  2. The response should be similar to
    Non-authoritative answer:
    text =
2. What to do next
  • If you do not have a connection, check that your DNS configuration settings are correct , and if not, adjust them accordingly. Then re-run the test.
  • If the above tool shows you do have a connection and your DNS configuration settings are correct but a scan is still running slowly contact Sophos Technical Support for help.

If you need more information or guidance, then please contact technical support.
