Try a forum search as this has been covered in at least two posts as far as I’m aware.
Did a forum search before I`ve posted, and did not find anything.
Depends on what you searched for ‘chromeinject’ http://forum.avast.com/index.php?topic=40713.0 and http://forum.avast.com/index.php?topic=40643.0 
Only joking, I guess you ned to know what term to search on.
