To stop the Adds -
In your ICQ folder (usually C:\Program Files\ICQ) you can delete the
following.. (If you're timid, you can always move them to another folder)
icqateima32.dll (removes advertisement downloading)
icqateimg32.dll (removes the loading of images)
icqateres.dll (removes part of the advertisement function)
You will get "ICQ ATEBROWSER 1.0" instead of advertisements..
this is from the technical support forums....i just searched them for this myself.
good luck
