It’s better to use the Control Panel > Add/Remove Programs before

I tried but it asked me for installation ! I didn’t understand why, I tried 3 times and I gave up this solution.

… anyway, did you use the same folder for installation? Which is it (full path)?

I removed the folder (setupfre.exe) and I downloaded an other from this page (in french but I show you in english) :

(avast! 4 Home - French version (length 11.65 MB))

I even asked another registration key :

(but I couldn’t use it because Avast doesn’t open)

Do you have any other antivirus in your computer? Did you have in the past?

Today I have 0 antivirus ! It’s really dangerous I know, but I don’t use my email box, I don’t read and open my emails, I only ‘surf’ on the web and forums.

In the past I had Norton but I removed it (and there is no other “symantec” files in my computer). And Avast was Ok before few days.

I hope you could understand me.

Thank you very much for your help, now I’m going to read the thread.
