Utorrent Self-update mac os x, how to block update?

Question

bittorrent

Not so long ago, I mistakenly installed the beta version of Utorrent 1.8.6, I did not know before that there would be advertising in the new version. I didn't like the ads. I sowed the old version 1.8.4. I asked for .app version 1.8.4 on the macovod forum, I deleted the version with ads. from the Applications folder, as well as folders along the paths.
Except, The torrent files themselves. not to re-add torrent files for distribution. I throw Utorrent.app version 1.8.4 In Applications, everything works fine. but after a while it updates itself, without even paying attention to the points: Automatically check for updates, Update to beta versions,
I think there is an option to block the update. is to put on something read-only rights.
