Hi aff501
As some say here in the forum: "Do not panick!!".
There is a sticky about this, you will find it here:
http://forum.avast.com/index.php?topic=14433.0The sticky is information when you actually do have the virus.
If as you say access protection is alerting, that will prevent it from infecting, and if it cannot, it will certainly put the thingie into the chest, where it can do no further harm. The chest is a sort of virus prison or closed sandbox, where malware is rendered harmless.
To be prevented further, pre-scan all the links inside your browser for malicious nodes before you really decide to go there using
Dr Web plug-in . It is a free service you can get from here:

Enjoy,
polonus
