>>>not sure if i DID download it from that link now
It's probably still safe (since there are several legitimate sites that host it) but, since I don't know which site you used, I can't actually guarantee it.
If in doubt, download and run the removal tool here:

(It's more thorough than simply going via your Control Panel)
RESTART YOUR COMPUTER. (That's essential; it forces Windows to flush the registry).
Download and install Malwarebytes Anti-Malware from my link above, ensuring that
(a) you click the grey button and not the green one ; and
(b) towards the end of the installation process, you REMOVE THE TICK alongside the option of taking a free trial of the 'Premium' version.
I can't be sure whether you'll then still see that User Account Control box. (You probably will). However you can then definitely proceed with confidence anyway if you do.
