"Trojan Horse Blocked" every time I open Chrome

[PerseLark]

Every time I open Chrome, avast! gives a "Trojan Horse Blocked" message: http://i42.tinypic.com/154dlbb.png

I recently re-installed Chrome. I ran a Malwarebytes quick scan and it found nothing. Does anyone know what's wrong?

Thanks for your help!

hi PerseLark,

You can attach all screenshots via "Attachments and other options" when creating a new post here.

Link appears to be a network block by Network Shield on a javascript instance.

Why did you need to re-install Chrome?  Are you getting multiple blocks at the same or different websites?

If you feel this needs to be looked into greater depth, follow the instructions on this page, and run only the first three programs listed.  All other programs are called on only when a malware cleaning expert asks them to be run, if needed:  http://forum.avast.com/index.php?topic=53253.0

Here, as above, you attach the resulting logs in your next reply.
