WebShield

Hello,
Yesterday I was on the internet, and avast! block a website, saying: Infection:Html:Iframe-inf

Did the web shield blocked the infection of the website or could my Mac be infected? What does the Webshield when it discover an infection?

(Sorry for my english, I’m french)
Thanks!

The site was blocked i.e. the malicious content did not reach the browser, so you may not be infected by that website.
