online videoconverter.com: spam and malware provider

Hi Peter Prinsen and welcome to the Community!

Did you download a file from that website? Also, is there any registration process before you can totally access their site? If possible, can you post here the exact link so that we could check? Kindly provide us too if there is a program that you recently installed before you noticed those changes on your computer. 

By the way, if you are sure that the emails you are getting are spam, kindly just unsubscribe from them. You may also refer to the link below for using the Antispam Toolbar.

I fear I did download something and installed it to convert the videos, the guys I worked for recommended it and since they are a big player in audiovisual territory (GRID in Belgium) I trusted there advice... I also worked in admin modus what can make things worse... I actually deleted anything that referred to that malware  in  google chrome and programs but it could be hidden somewhere else. I'm working on a huge workstation with many terrabite of  raid solid state and other disks so it could be hard to find it! Didn't know that unsubscribing could help I thought it makes things worse, wasn't aware of the antispam toolbar... I never download emails, they stay on the Telenet webserver to be accessed anywhere. But it seems the browser is hacked because i get spam for anything I looked for on the net... From stairlifts to guitars etc.  I hope it isn't google itself ! I will have a look in my history to find the exact link. Trends is actually blocking any website  (dangerous website) proposed by the popup window  (kind of Facebook-like messenges in the lower right corner of my screen.
Thank you so far!

Could find in my history because I deleted it somewhere in december and reinstalled google chrome trying to solve the problem, going back to my mails concerning that client I can see I got the link on october 27.
But i still can find the deleted downloads. In fact online video converter is an online service that converts the links you put in Like Youtube for instance and gives you a converted mp3 or vid of that file to download, it actually works but I fear it does more than just giving you an mp3... Here's a typical link from one of these downloaded files: http://s7.onlinevideoconverter.com/download?file=j9i8j9d3h7a0a0c2
