I had AdwCleaner version 7.1 (or 7.1.1) and upon running, the product announced a new version available. I run 7.1 anyway with no troubles.
Later, I used Bleeping Computer's download page for AdwCleaner and then ran the program. Product gave message again, new version available and ask if I want to download it. I already did that.
Maybe forum or B.P. site administator needs to fix the download link! The link needs to bring the user version 7.2.
