The same properties of the file indicate that the signature is not valid. “The digital signature of the object was not verified. ” Even Kaspersky’s firewall indicates this. “Error when checking the signature.”

Oh, thank you very much for providing that tool! Seems useful. Two last questions: Once the analysis of the file has been done, can I ask you for the full reports on the file to avoid requesting a demo on https://opentip.kaspersky.com/. I understand that this question does not involve your job duties but, any ideas on why VirusTotal point out that “the digital signature of the object did not verify”? That is what bothers me the most. I thought that the reasoning behind that was that the certificate was expired (valid to 02/03/2021) but when I compare this with another Adobe setup with the same signature validity, VirusTotal says that the signature is valid. What a headache ...

Thank you very much for the effort, but I still have a couple of questions: 1. So is it signed by Adobe or is it a modified executable? 2. If it is consumer oriented, could you explain what have you done to determinate that it is clean? If not, how could I conclude on my own (for the next time this happens) that a file is safe when Kaspersky says one thing but sources like virtustotal.com say others?

Hi, can you pm me the link to the file? Done.

@Berny The information is the same. File signed, possible risks not found and file security level not classified, so should I trust this file despite VirusTotal.com information about the signature verification?

I got a setup file (SHA1 Hash: 1C27A70F922A95F66F58D8E4B7E91D92C84DA6E3), theoretically from “Adobe Inc.”, where Kaspersky File Supervisor says that it is indeed signed by “Adobe Inc.” so I can trust it even though the file security level is not classified, why would I not when it is signed by a well-known publisher. But when I contrast that information with another database like “VirusTotal.com” I get the following: “The digital signature of the object did not verify”, implying that the file in question is modified and unreliable. Is Kaspersky Application Advisor giving misleading information here?

Hi @Wesly.Zhang! SOLVED: For silent installation it is needed a full installation package (offline setup).

@FLOOD Product was not detected, select product from list to force remove. This is the right picture, sorry.

@FLOOD, Product was not detected, select product from list to force remove. Yes, same result. I’ve been able to attach the log file generated after trying again silent installation command. Hope now it is useful.

@FLOOD, All Kaspersky and Temp folders cleared. Still not working. I forgot to mention that I tried all of this running a clean Windows 10 64 Bits Virtual Machine. So it has nothing to do with system files, in my opinion. KavRemover.exe only displays one option (Home Products). I could not print screen, sorry. Thank you for your patiente, flood.

@FLOOD, I am developing a simple C# application for people like my friends, who does not know to manipulate a computer in any way. So that my app would automatically install essential softwares like Kaspersky Antivirus. Common folders, like kaspersky lab inside programfilesx86 and programdata, and Kaspersky Lab Setup Files inside programdata. From the data: What is “KIS 2020 MP0 family patch H”? It seems to be the problem.

@FLOOD Birthday date: 1990-01-10 (separated by scripts). No install logs are generated since command line does not work. If you wish, I could install KIS using graphical installer and upload it’s logs.

Hi @FLOOD, thank you for your fast response! Before trying this method, i have successfully installed Kaspersky Internet Security with no problem. Anyway, Kaspersky setup (kis20.exe) is supposed to check incompatible software automatically. My cursor starts loading but nothing else happens.
