Respond to incorrect Norton alerts that a file is infected or a program or website is suspicious

A false positive occurs when your Norton product incorrectly alerts that a file is infected, or a program or website is suspicious. Common indicators of a false positive are:

  • Norton detects a threat in a file that you believe is unlikely to be infected (for example, files with extensions such as, *.txt, *.dbf, *.log, *.hlp).

  • Norton alerts that a file or program developed and created by you or a legitimate company is suspicious, or is a threat

  • Norton indicates that a legitimate website is malicious

  • Norton blocks downloading a file as suspicious

Report a false positive

Before submitting a false positive, make sure that your Norton product has the latest definition updates. Run LiveUpdate to install all the available updates for your Norton product and then run a Full system scan.

If the false positive still occurs with the latest definitions, report it to us. The link to submit a false positive differs based on the exact detection, or the alert you receive.

To know more, read Report a Suspected Erroneous Detection (False Positive) to Norton .

What to do after you submit a false positive?

The submitted file will be analyzed for any potential false-positive detections and the updated definitions will be released to address the issue within 48 hours. In the mean time, you can try updating the definitions and scan the incorrectly detected file or application at frequent intervals.

 

Perform the following steps only if your business is getting impacted, or if you are certain that the file is safe, or if you are a developer who created the file.
