Edit: By the way Bob is my Avatar blurry to you?
Yes it is, there also seems to be another element to your image, almost like a filter/watermark over the top, from photobucket. See attached I have blown it up.
You might want to check the original image if your are pulling it in from photobucket or import it into the Avast forum avatars area in your profile.
EDIT: I see it is pulled in from photobucket and checking the source location the image is the same blurred. So you will need to investigate that or replace the original.
