Trojan

I have Avast anti virus. Today when I was going to read message on facebook it said in a message that it found a threat a trojan called JS:Agent-BWQ [Trj].
So how can I remove this?
Thanks in advance.

I have the same problem but ony in Chrome. Opera works fine

I have the same problem on chrome and firefox

Looks like a false positive, see here http://forum.avast.com/index.php?topic=126372.msg949044#new

Ok but how do I solve it?
Btw I am using google chrome.

When I click to read a message on facebook I can not see the message and I get a message from Avast that a Trojan hourse has been blocked.
Thanks in advance you can help me fix this.

Hello,
FP will be fixed in next VPS update.
