Facebook Messages Trojan

Hi guys,
This morning when I try to open my inbox messages on Facebook I get notification on avast that a trojan has been detected in it. I use Google Chrome. I have read that other people had the same problem. I add two pictures of the two messages of trojan. What can I do to resolve this problem? Thanks in advance!

Hello,
it will be fixed in next VPS update.

Hey I had exactly the same problem. The way that I got the problem to stop and it was a pretty easy fix was to update avast (the whole shabang) not just the add ons. Once you have updated it you just do the standard restart of your Laptop/PC and its fixed. (hopefully)

Hope this helps with any problems.
