Trying to find traces of a program that appears invisible

[James]

A few years back I installed the free internet security program offered by my ISP (F-Secure). After a year, I uninstalled it and installed a different program.

Yesterday I decided to try the consumer install of Windows 8. Everything was fine until it discovered that F-Secure was still on my system and needed to be removed.

Now... here's the problem. I first brought up Revo Uninstaller but there were no traces of F-Secure there. Then I searched in the listing of programs but found nothing there. I then did a search on my C-drive and still found nothing.

Then I looked in Regedit and found one instance of it which I cautiously removed. But still... the Win8 installer insists that F-Secure is on my system and needs to be uninstalled.

How is it finding this program (or traces of it) and how do "I" find it and remove it?

I assume you uninstalled F-Secure the the official way.

You might want to try the Uninstallation Tool.exe (Uninstallation Tool (C) F-Secure Corporation. Distributed under the terms of the F-Secure License Terms)
Please refer to this page, particularly the second half.

Apart from the built-in ones from Microsoft, I haven't been using anti-virus and so applications on all my Windows installations, since those were all under Parallels Desktop virtual machines, and I hardly use them. I did try Kaspersky once (came with Parallels Desktop for Mac), but I did not like it.

Thanks. I'll take a look.
