There is no need to download anything to solve this problem. You installed the "CinemaPro" trojan. Take the steps below to disable it.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
Back up all data before continuing.
1. Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
~/Library/LaunchAgents
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return. A folder named "LaunchAgents" will open.
2. Inside the folder you just opened, there may be files with a name beginning in any of the following ways:
cinema-plus
cinemas-+-plus
com.cinemapro
com.extensions
Safari Security
shopy-mate
UpdateDownloader
Move all such items to the Trash.
Log out or restart the computer. The trojan will now be inactive, but there are a few more components of it that should be cleaned up.
3. Do as in Step 1 with this line:
~/Library
A folder named "Library" will open. Inside it there may be a subfolder with a name beginning
cinemapro
If so, move that subfolder—not the Library folder—to the Trash.
4. Open this folder in the same way as above:
~/Library/ScriptingAdditions
and remove an item named
BrowserHelper.osax
if present.
5. Open this folder in the same way as above:
~/Applications
This is not the usual Applications folder, but a different one inside your home folder. Look for an application with a name beginning like this:
cinemapro
and move it to the Trash, if present.
Empty the Trash.
6. From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall all extensions you don't know you need. If in doubt, remove all of them. None is required for normal operation. Do the equivalent in the Chrome and Firefox browsers, if you use either of those.
