Hey, I also started getting the audio file or little kids or something like that and the ad’s didnt bother me but then they did when they started ‘audio ads” so I changed a few things try this….
Where you Installed aim…search for the folder aim(also its probably this path…My Computer, C Drive or Local Disk Drive,Program Files, aim…Then inside that file should be 2 files one is called advert.ocm and the other admin.ocm, DELETE the advert.ocm file and recycle it, THEN RENAME the admin.ocm file to…..advert.ocm and if you are in aim exit and sign back in but if not then just sign back in and no more ads…
