1. What antivirus program did you have before Ad-Aware 10 was installed?
2. What do you mean with "jai"? I don't think it is an English word.
3. What program was installed by default?
4. Have you tried to install Ad-Aware 10 again?
Maybe better if you both write in French and write the English translation, then I can find the translation for a single word if necessary. Or maybe someone that can speak French and English sees it and can translate.
