AT&T - 0.254% Detection Rate *
Did you just download a file that has been digitally signed by AT&T and wonder if the file is safe? If so, please read on.
You will typically notice AT&T 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 view the additional details from the AT&T digital signature with the following procedure:

Here's a screenshot of a file that has been digitally signed by AT&T:
As you can see in the screencap above, Windows reports that "This digital signature is OK". This means that the file has been published by AT&T and that the file has not been tampered with.
If you click the View Certificate button shown in the screengrab above, you can examine all the details of the certificate, such as when it was issued, who issued the certificate, how long it is valid, and so on. You can also examine the address for AT&T, such as the street name, city and country.
VeriSign Class 3 Code Signing 2010 CA, VeriSign Class 3 Code Signing 2004 CA and VeriSign Class 3 Code Signing 2009-2 CA has issued the AT&T certificates. You can also examine the details of the issuer by clicking the View Certificate button shown in the screenshot above.
