Hello @AnnikaBarbara

Welcome back! 

  1. Which www did you check, please provide a URL? 
  2. From our last discussion, you were wishing to try KIS trial version, is that still your requirement? 
  3. The download link on the Kaspersky Internet Security support page is for the Global version, you may wish to check that? 

KIS hash information from the KIS Trial installer we tested for you in your last post, 17th October 2020

 

 

Please post back?

Thank you for answering my question. 
I used the provided link and it resulted in different hash number. Tested it second time and again different hash…

 something goes wrong... will try it more times and observe the result.

Tried from different browser... all installer files have different hashes

Hello @AnnikaBarbara

  1. Are you downloading the installer files, then uploading each exe to Kaspersky Threat Intelligence Portal to check the hash? 
  2. Post all URLs for “all” installer files you’re referring to please?
  3. Post full screen images of the tests please?

Thank you:pray_tone3:

Oh no… I am just checking the hashes with Windows power shell.

Could you maybe download an installer file the second time and check ifthe hash changed? I have no second computer at my disposal..

Very interesting… I searched on Google and found the same problem here in the forum: „Different KIS Trial installation file on each download “

Hello @AnnikaBarbara

Different KIS Trial installation file on each download & @Schulte’s advice at the time:

I think the download is safe. Probably the downloader gets its own installation ID or timestamp.
The real installer will check every single file for integrity later during the installation. If anything is suspicious, it will abort.

Hello,

I add a little information, Do you check the digital signature of the installation file? It has digital signature tab in the property of the file?

If the installation file lost its digital signature. There are two possible causes of this problem. The first one is that the downloading file is interrupted and the file download is incomplete. The second possibility is that there is a malicious program infection on your computer, the newly created exe executable file is modified by malwares to invade some code and the digital signature is lost. So please tell us…... Please tell us the result of the digital signature check.

Regards.

Hello Wesly,

which region site are you using? I tried the USA website and the hashes do not change. But when I change the region to Germany/Switzerland - every download has individual/different hash. 
I think UK regional website also gets individual hashes. 
what bothers me is that the digital signature has no “time stamp”...

Hello @AnnikaBarbara

Which download url could you provide to here?

Good day, 

It is normal that downloaders have different hashes, as they are formed “on the fly” at every download attempt.  Timestamps in downloaders are not present currently, but we plan to add them in the future.

Igor

How can I be sure that the installer I use is properly formed?

If there is an issue with the preparing the file this „wrong“ file is them signed and I do download it. 

It would be nice to have a file with the same hash for all downloads. For that reason I would know other people use exactly the same installer.

hi @AnnikaBarbara , the fact that you download the file from Kaspersky site + the file is signed - should be enough to be sure the installer is properly formed.

But there is not  a „standard“ download link which leads to always the same file?

hi @AnnikaBarbara ,

There is not, and it does not look like an issue to me, because there is a standard place where you download the installation file + the file is signed. 

So, download the file, check the signature (if you think this check is needed), have a fuzzy warm feeling of being on the safe side. 

Regards,

Igor
