Avast Issue "HTML:Script-inf"

Solved

Hello,
I have Avast as my antivirus and for the past few hours, I've been getting a message from the antivirus on almost every site I visit (trustworthy ones like Wikipedia and even Comment ça marche) saying that it is a malicious site, and it stops loading the page.
It says:

Object: http://fr.wikipedia.org...|>{gzip}
Infection: HTML:Script-inf

(see the image: http://img25.imageshack.us/img25/8944/image1oi.jpg )
It's unlikely that it's a virus coming from the sites since it's the same on all the sites I visit...

So I'm posting this with Avast disabled. Otherwise, I can't browse the web...

Do you have a solution, please?

Configuration: Windows 7 / Firefox 3.6.16
