False positive, how to set signature exclusion.

How do I know which signature to exclude?

 

I'm getting a false positive on a file... I know for a fact that it's clean.  I'd like to add this signature to exclusions because this file gets moved around some times and I don't want to have to add it to file exclusions every time I move it.  Here's the detection log.

(I removed the file name)

 

c:\documents and settings\*******\desktop\*****.dll

Re: False positive, how to set signature exclusion.

Is there a reason to remove the file name?

Hello zSandman

 

Welcome to the Norton Users Discussion Forum

 

If you have a file which you think is a false positive, you can submit it to Symantec for further analysis.

 

Please use this link if you think that a file is a false positive:
https://submit.symantec.com/dispute/

If there is a possibility that the file might be infected, please submit it to Symantec using this link:


https://submit.symantec.com/websubmit/retail.cgi



Another alternative which is fast you can use Threat Expert:

(Thanks to Yaso for providing the links)

 

If it turns out that it is a false positive, they should adjust the definitions to reflect that.

 

Please let us know if this has helped.

Hi zSandman,

 

I agree, is there a reason to remove the filename?

 

Is this a file you have created or did it come from somewhere else? If not created by you, how do you know for sure it is safe?

 

As Floplot said this file should be submitted to Symantec for analysis and if it is truly safe they will make adjustments accordingly.

 

Best wishes.

Allen

Re: False positive, how to set signature exclusion.

The file name is antiwpa.dll, the reason I removed it is because I don't want this thread to get off topic.

It's not a virus and from reading other threads here it will not be excluded from Norton's detctions as a false positive, but that's not what I'm asking... 

I'd like to know what signature should I exclude in NAV so this file doesn't get picked up radless of its location.

[ Edited ]

So, there is no way to find out which signature to exclude?

Here is a report about that .dll

Are you sure about this file?
