CA - 0.056% Detection Rate *

Did you just run into a file that has been digitally signed by CA? If that's the case, please read on.

You will typically see CA when clicking to run the file. The publisher name is then displayed as the "Verified publisher" in the UAC dialog as the screengrab shows:

You can view the additional details from the CA digital signature with the following steps:

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

Here is a screenshot of a file that has been digitally signed by CA:

As you can see in the screenshot above, Windows reports that "This digital signature is OK". This means that the file has been published by CA 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, etc. You can also examine the address for CA, such as the street name, city and country.

VeriSign Class 3 Code Signing 2004 CA and VeriSign Class 3 Code Signing 2009-2 CA has issued the CA certificates. You can also examine the details of the issuer by clicking the View Certificate button shown in the screenshot above.

CA Files

The following are the CA files I have collected, thanks to the FreeFixer users.

The FreeFixer tool treats files from CA as trusted, which means that the CA files will appear with a green background and that there is no removal checkbox for the file. However, as you can see in the scan results below, a few of the anti-virus scanners detects the CA file(s). My guess is that those detections are incorrect and that the files are safe. It's unlikely that CA would ship a malware file.

Scanner and Detection Names

Here is the detection names for the CA files. I've grouped the detection names by each scanner engine. Thanks to VirusTotal for the scan results.

As mentioned above, I think these detections are incorrect since it is very unlikely that CA would ship a malware file.

* How the Detection Percentage is Calculated

The detection percentage is based on that I have gathered 1790 scan results for the CA files. 1 of these scan results came up with some sort of detection. If you like, you can review the full details of the scan reports by examining the files listed above.
