Ok i would suggest orbit downloader. But remember to use the /NOCANDY switch while installing.
For eg: You have saved orbit.exe on your desktop, do the following

Open command prompt. Go to start menu- type cmd in search and press enter

Now in cmd type cd desktop

after that type orbit.exe/NOCANDY

Note: Replace orbit.exe with the file name of the installer like xyz.exe

Then the open candy ad showing process wont be launched.
