= False Positives from Anti Virus Software
Usually right after a new release, some anti-virus scanners claim to detect virus or malware signatures in 
the Gpg4win installers. 


If your antivirus software claims that Gpg4win contains a malware signature you should:

* [[https://www.gpg4win.org/package-integrity.html|Verify the integrity of the downloaded file]] (to ensure that it was not manipulated on transfer).
* Notify the publisher of your antivirus software that you think this might be a false positive.

Additionally [[http://virustotal.com | VirusTotal]] can help to get an overview about the results from other scanners.
Usually there is a handful of (often times different) signatures while the overwhelming majority does not find anything.
If your scanner is one of the outliers this is a good indicator that it is indeed a false positive.
