Problem Downloading Horizon

When ever I try to download horizon-setup.exe a message popsup telling me that the file was moved or removed.

EDIT: It was avast sending the file to another location, but after disabling avast horizon started installing random ■■■■ into my pc, is this normal?

Random ■■■■ you say? The Installer might include some optional adware (these can be declined using the “custom install” option.

Could you tell us what ■■■■ got installed?

The installer didnt have any custom setup options, also while I was searching the horizon directory I got two new files: tuneup utilities 2014 and something else
