How to Uninstall and Remove F-secure Completely From Your Computer?

When I decided to exchange ESET Smart Security for F-Secure Internet Security, the first thing I needed to do was uninstall the unwanted F-Secure. I have removed F-Secure by following the steps here: go to Start Menu>Control Panel>Add or Remove Programs and highlight F-secure in the currently installed programs list and then click Remove button.

It seemed that F-secure was just gone with only a folder left in disk C:Program files\F-Secure Internet Security. I was supposed to delete the folder manually and it worked. I thought the F-Secure have been completely removed from my system.

Then I was going to install ESET software now. But when I went through the install steps, there was a warning about that you need to stop the application first before you install ESET. In the box, F-Sercure was shown. That really surprised me a lot. Then I needed to stop the installation of ESET until completely remove F-Secure.

At last I tried to reinstall F-Secure again and downloaded Special Uninstaller. After I have installed F-Secure again, I followed the instructions here to uninstall F-Secure:

First, use the Add/Remove Programs to uninstall F-secure.

Second, go to Special Uninstaller's interface and click "Force Uninstall".

Third, click "OK" to skip pop-up "It is recommended that you should firstly try the "uninstall" function. Are you sure to forcibly utilize this function?"

Forth, choose F-Secure's path by click the button on the right side of the second blank.

Fifth, click the program folder and Click "next" to start the removal.

Sixth, follow the on-screen steps to finish the uninstall process. When I came back after I rebooted my PC which can completely remove all the associated files of F-secure components. There was no path of F-Secure left when I tried to install ESET.
