ADANAK- worm or virus - how to remove

Last November, ADANAK “Browser adapter” has somehow latched on my PC. AVAST is constantly blocking ADANAK’s attempts to access web and transfering same to quarantine.
However, ADANAK is immediately re-installing itself and all my attempts to remove it have failed.
Does anybody have a suggestion how to remove this pest ?
I have attached a screen-shot of the “Windows Explorer” displaying files that are involved - zipped file from which ADANAK is re-installing itself is protected with the unknown password.
