Hi,
"vlc.de" offer downloads of open source software. Is the owner supported by you, because maybe the install comes with malware.
He writes, his install only changes the startpage of all browsers. Is there a possibility to deaktivate his site, or do you want him to make the vlc-project more public.
Sorry for my bad english i am german. I didn't install it from his site, but maybe all newbies have to be warned!
Cya
