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 will probably notice Kaspersky Lab when double-clicking to run the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screencap shows:
You can view the additional details from the Kaspersky Lab digital signature with the following procedure:
Here is a screenshot of a file signed by Kaspersky Lab:
As you can see in the screenshot above, the Windows OS 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 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 see 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 screenshot above.
These are the Kaspersky Lab files I've gathered, thanks to the FreeFixer users.
The FreeFixer tool treats files from Kaspersky Lab as trusted, which means that the Kaspersky Lab 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 Kaspersky Lab file(s). I'm pretty sure those detections are false positives and that the files are safe. It's unlikely that Kaspersky Lab would ship a malware file.

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 false positives since it is very unlikely that Kaspersky Lab would ship a malware file.
|Bkav||HW32.Laneul.rqmm, W32.HfsReno.5A42, HW32.Laneul.hmko, W32.HfsReno.45EC, W32.HfsReno.C1F6, W32.HfsReno.A402|
|Emsisoft||Win32.Almanahe.D (B), Trojan.GenericKD.1603822 (B)|
The detection percentage is based on that I have gathered 41701 scan results for the Kaspersky Lab files. 17 of these scan reports came up with some sort of detection. You can review the full details of the scan reports by examining the files listed above.
The analysis is done on certificates with the following serial numbers:
