Before, I had made some trials killing every progam that looked like a Comodo program or related, it seems it wasn't enough, though.
Thx for your help and a Boo! for Comodo. True, the antivirus is free, but I take sth free when it's supposed to help, not create problems.
Edit: Finally, after like 15 trials I got the "Instalation Complete" message. [:D]
