IE infected

[taille50]

On my laptop each time I use IE to browse the Internet, there is popups opening even when I don't click on anything, and when I close the new windows with the ads, it closes also the original windows I was surfing. I also have Chrome on my machine but I couldn't download anything with it and it was behaving weird. I had to reinstall it yesterday and now it seams to work fine.
So I was feeling I had a virus or something especially that my laptop stayed with no anti-virus for a while, but when I scan my computer with Stinger and Avast and they both found nothing!
does someone have an idea of what's going on?
Is it a virus, and if yes why Avast don't see it, and if not what is it?
Thanks
