URGENT: Might have accidentally installed malware from Frostwire Installer

[tacorrito]

I decided to update my Frostwire and thought it would just be a routine install. However, I breezed through the Installer and realised that I just clicked Accept on installing a program called ZipCloud. (I wasn't able to uncheck it, it was in small letters on the bottom)

I realised my mistake, and when the prompt for my password to change files on my computer came up, I didn't enter my password but kept cancelling the window. Then the installer said it was successful, and then this was the next window.

I looked for ZipCloud on my computer, but it's not present in my Applications. Was I successful in stopping the installation, or is it hidden even deeper now?

What I would do:

1. Install and run AdwareMedic (http://www.adwaremedic.com/index.php).
2. Check the extensions/plug-ins in your browser (if found something that does not belong/was not there, delete it).
3. Clean webdata of your browser (cookies, cashe etc.).
4. Install and run EasyFind (http://www.devontechnologies.com/products/freeware.html). In Search type ZipCloud, delete all entries found.
5. Reboot.
