I think that I deleted all the program files for web cake, Babylon toolbars, vgrabber and similar ones. even those hidden in temporary folders.
several scaners (microsoft, panda, ccleaner, malwarebytes..) told me that the pc is clean
then I looked in regedit and saw several keys still refering to those programs and others like zoomit which I had uninstalled
then I ran Adwcleaner and found many keys refering to the unwanted programs, I just dared to delete a few ones.
then I had the upgrade from windows 8 to windows 8.1
Now I try to run the brand new version of Adwcleaner (downloaded from http://general-changelog-team.fr (not the mirror from CNET, as some users have doubts on whether they got infected there), but now I get so strong warnings from WOT about the website, and from Windows against running the last version of Adwcleaner that I doubt.
Why should I not run Adwcleaner last version?
Another better way to clean the registry of the obvious references to wholly uninstalled (I believe) malware?
