I have got a virus, can you check from where it comes?

Hello, I have got a virus, funmood virus.

The virus filled PC with things that I removed with antiviruses tools
virus did put a bar on firefox
And a plugin on firefox.

Now my PC is clean but I would like to know from which program it comes.

I have downloaded and executed 3 programs in a row downloaded from here:

Download - Screamer Radio no portable version
Download version 2.2 | Radio? Sure!
Raimersoft - Downloads ranmaradio (first link).

Now, can anyone try to find and check [in a safe way] from which link I have got the virus please?

Thank you in advance
