This should help, Thierry:
Either: go Control panel > folder options OR: in an explorer window > tools>folder options; - then view tab, and press Show hidden files and folders.
==Download fixwareout from http://www.bleepingcomputer.com/file...Fixwareout.exe - and save it to your desktop.
Double click Fixwareout.exe to start the Fixwareout Setup Wizard, click next and then install. Ensure that Run fixit is checked, and click on Finish. After the fix follow the prompts. You will be asked to reboot your computer, and it may take longer than usual to load - this is normal.

Next check some settings....In control panel select the Network and Internet Connections , rclick on your default connection, usually local area connection for cable and dsl, and lclick on properties. Click the Networking tab. Dclick on the Internet Protocol (TCP/IP) item and select Obtain DNS servers automatically. Press OK twice to get out of the properties screen and reboot if it asks.

Now we have to flush the DNS cache: Go Start > Run, type cmd and click OK.
In the command screen, type in cd\ and then press Enter. Now type in ipconfig /flushdns and then Enter. [space after ipconfig]. Type Exit.

FIX CHECKED ENTRIES....!!
Start Hijackthis, do a Scan Only and place checkmarks against all of the following, and then press Fix Checked:

Okay, please run HT again and repost with the fixwareout log.

Hello Gerbil,

Thank you very much for your help!

I did as per your advice. After the first steps, the HT entries to be checked and fixed were not there anymore. I guess this is a good sign.

Here are my logs for HT and Fixwipeout
