Positives from http://m.addthisedge.com today

[Gagir]

From this, I gather that some thing it is a false positive: http://support.addthis.com/customer/portal/articles/search?q=avast

So, is it a false?

It seems that quite a few sites are using this, quite annoying!

Getting a 404 error on that URL, so no alert for me.

If you could attach a screenshot of the avast alert.

I was getting this from any site using their banner service.
This is their forum: http://support.addthis.com/customer/portal/questions/606668-urgent-avast-false-positive

This site is quite serious and was giving the alert: http://www.invitrogen.com/site/us/en/home.html

Unless a new def file was released by Avast yesterday noon eastern time, the banner site corrected the problem.
Or even better, site webmasters stopped using this service.

I can't find data or a log from the network agent that I could share.

I'm not getting an alert on the invitrogen.com/site/us/en/home.html link you posted. For the future when posting suspect URLs change the http to hXXp to break links and avoid accidental exposure to a suspect site.

You can check the C:\Documents and Settings\All Users\Application Data\AVAST Software\Avast\log\nshield.log file (XP location) or C:\ProgramData\AVAST Software\Avast\log\nshield.log (Vista, win7), as that should contain the network shield alerts.

For me a 1x1 image doesn't necessarily mean it is a web beacon. I used to use them as spacers a clear image may be 1X1, but you can assign a larger area for the 1 pixel image.

I actually had a browser crash whilst checking this out as it tried to get the shared-static elements.
