downloads piggybacking on install?

when i installed Audacity on my win7 pc i think a few other programs somehow got installed:
Taplika
ProPCCleaner
KNCTR


i may have done something incorrectly, but i was able to unstall them.
NO REPLY NECESSARY…

Please ensure that you download Audacity from the official download locations given on the Audacity website: http://audacityteam.org/download/

Note that even the official download hosts have adverts, so take care to download only Audacity and avoid big green download buttons that may be present in adverts.
(this is good advice when downloading anything from the Internet).

I’ going to reply anyway…

You didn’t download from the official site [u]http://audacityteam.org/download/[/u].
