Kaspersky Lab - 0.039% Detection Rate *

Did you just download a file that is digitally signed by Kaspersky Lab and wonder if the file is safe? If so, please read on.

You'll probably notice Kaspersky Lab when running the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:

You can view the digital signature details for Kaspersky Lab with the following procedure:

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

Here is a screenshot of a file signed by Kaspersky Lab:

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

If you click the View Certificate button shown in the screenshot 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 Kaspersky Lab, such as the street name, city and country.

VeriSign Class 3 Code Signing 2010 CA, DigiCert High Assurance Code Signing CA-1, VeriSign Class 3 Code Signing 2009-2 CA and VeriSign Class 3 Code Signing 2004 CA has issued the Kaspersky Lab certificates. You can also see the details of the issuer by clicking the View Certificate button shown in the screengrab above.

Kaspersky Lab Files

The following are the Kaspersky Lab files I've collected, thanks to the FreeFixer users.

The FreeFixer tool treats files from Kaspersky Lab as safe, which means that the Kaspersky Lab files will appear with a green background and that there's 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 Kaspersky Lab file(s). I'm pretty sure those detections are incorrect and that the files are safe. It is unlikely that Kaspersky Lab would ship a malware file.

Scanner and Detection Names

Here's the detection names for the Kaspersky Lab files. I have 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 Kaspersky Lab would ship a malware file.

* How the Detection Percentage is Calculated

The detection percentage is based on that I have collected 43418 scan reports for the Kaspersky Lab files. 17 of these scan reports came up with some sort of detection. If you like, you can view the full details of the scan reports by examining the files listed above.
