Where on the website can I locate the F-Secure MD5 or SHA-256 hash to compare against the installer file I found in my Windows PC?

    Hello,

    Where on the website can I locate the F-Secure MD5 or SHA-256 hash to compare against the installer file I found in my Windows PC?

    maybe is nowhere.

    Сan you try to check the digital signature of the file (certificate)? I think it is hard to damage or change the file while keeping a valid certificate. Correct me if I'm wrong in this opinion.

    Then, the installer (as I think) checks its own integrity and if something is wrong, then accordingly there will be an error. Such as if the download was interrupted / saved as incomplete.

    The current installers will most likely require an F-Secure account, so you can also try downloading a "fresh" installer from My F-Secure portal (my.f-secure.com). To be sure of its origin.

    I admit the possibility that for some solutions or some specific installers there may be a checksum somewhere in some form for verification on their web-resources. Also, probably official representatives of Support can confirm or check whether the given SHA-256 or MD5 applies to their software.

    Thanks!

    Yes indeed, the file is signed and when running it, Windows will ask if you want to allow it to make changes. If the signature is valid, it means that the file is unchanged and you can trust it. Then you will see UAC dialog like this:

    If however the file has been tampered the signature will be broken and Windows will show UAC dialog like this:
