STOPzilla - 0.05% Detection Rate *

Did you just stumble upon a download or a file on your computer that has a digital signature from STOPzilla? If that's the case, please read on.

You will probably notice STOPzilla when clicking to run the file. The publisher name shows up as the "Verified publisher" in the UAC dialog as the screenshot shows:

You can also view the STOPzilla certificate with the following steps:

  1. Open Windows Explorer and locate the STOPzilla file
  2. Right-click the file and select Properties
  3. Click on the Digital Signatures tab
  4. Click on the View Certificate button

Here's a screenshot of a file signed by STOPzilla:

As you can see in the screenshot above, Windows reports that "This digital signature is OK". This implies that the file has been published by STOPzilla and that no one has tampered with the file.

If you click the View Certificate button shown in the screenshot above, you can view 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 view the address for STOPzilla, such as the street name, city and country.

Thawte Code Signing CA and VeriSign Class 3 Code Signing 2010 CA has issued the STOPzilla certificates. You can also examine the details of the issuer by clicking the View Certificate button shown in the screengrab above.
