Hi,
I’m using avast! Internet Security 6.0.1203 and Mozilla Firefox 5.0. And I found out that when I’m posting in Google+, there will be some text from WebRep added automatically to my posts. It looks like a similar bug with Gmail in some previous versions. Now the problem in Gmail is fixed, hope the problem with Google+ can be fixed soon.
Just had someone ask me where my sig comes from. “What sig ?” I thought. Then noticed :
WebRep
Overall rating
is being added to each of my posts, sometimes twice.
Can’t see anywhere in Avast’s settings to prevent this, so as you suggest it’s a bug, hopefully it will be sorted soon 
Yes, seems this is a bug…
