Tamper protection is disabled

There is an item in the settings:

Tamper protection

with the description:

Tamper protection prevents malicious applications from terminating the product's central security processes.

and the information:


Tamper protection cannot be switched on. You must reinstall the product.

What does this mean in concrete terms?

Do I first have to uninstall F-Secure Internet Security via the Windows Control Panel and then reinstall it? Or does it mean something else?

Many thanks for your help!

    Hello @m172nld

    Welcome to the F-Secure Community and thank you for your post.

    The error you encounter maybe encountered as a result of the feature malfunction hence the need to reinstall the program. Once the program is reinstalled you should be able to enable or disable the Tamper Protection feature as designed.

    You can uninstall the program from your Windows Control Panel or using the F-Secure uninstallation tool: https://community.f-secure.com/common-home-en/kb/articles/5439-how-do-i-uninstall-f-secure-products-using-the-uninstallation-tool

    Hi, marmab,

    it happened as I feared:

    After deinstalling F-Secure the installation-CD did not work. Next I searched the web for F-Secure-install possibilities and was told to update free to F-Secure-Total.

    What I did.

    Then I saw that my runtime for the program ends in 30days while my "real" runtime ends in 2025.

    so I deinstalled the "Total"-F-Secure and downloaded F-Secure from the website where I bought it. But again I am told that the runtime ends in 30 days.

    BTW: Tamper protection is working now. But THAT was not really what should happen...

    Any ideas how I can get back my F-Secure-Internet Security Version 19.1 expiring 08.06.2025?

    Best regards

    Hi @m172nld

    From what you write I'm guessing that you have been using a version of the program based on license codes so far. It is currently not possible to install this version. You installed the account-based version in My F-Secure on your device and created a test account, which is valid for 30 days.

    Do you have the code for your current license? If so, send it to me in a private message on the forum. 

    I will try to activate this license from the code in your My F-Secure account. 

    I will be waiting for your private message.

    Have a great day.

    Making every digital moment secure, for everyone

    Hello, Pawel, I'd like to send you a private message but can't find how I can do it. Going to your profile I can't find any "Send a private message to Pawel" or something alike...
