Notepad++ - 0.184% Detection Rate *

Did you just find a file that has a digital signature from Notepad++? If that's the case, please read on.

You will probably see Notepad++ when clicking to run the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:

As you can see in the screenshot above, Windows states that "This digital signature is OK". This means that the file has been published by Notepad++ and that the file has not been tampered with.

If you click the View Certificate button shown in the screenshot above, you can see all the details of the certificate, such as when it was issued, who issued the certificate, how long it is valid, etc. You can also examine the address for Notepad++, such as the street name, city and country.
