How Do I Fully Erase "Drive Genius 4 DrivePulse™"

I was trying to do a task using some new software and I downloaded Drive Genius 4 DrivePulse™ The product didn't work and I didn't want it on my MacBook anymore. I deleted it from the Applications folder and did a 'Full Erase' with Dr. Cleaner, which usually gets rid of extra files from software I've deleted. I can't find any traces of it in Finder, including the original Application and files with keywords like 'DriveGenius', 'DrivePulse'. Everything should be deleted. But after Drive Genius was supposedly gone for good, I noticed in my Menu Bar, a new application symbol. Guess what? It's Drive Genius! When I click it, I see the menu in the first picture. Also, when I right-click a file, there's a new option to 'Erase' my file. When I click this, I get a popup from Finder asking to destroy the folder. Also notice a different popup, also in the third picture, mentioning the fact that I downloaded the program as a free trial. Obviously, Drive Genius is not completely erased and I want to get rid of it.

I have several questions:

1. Could Drive Genius be harmful to my computer, Spyware, Malware, etc.?

2. How do I completely erase it from my computer?

3. Why is there no software removing option from the menus I see?

4. Did I do something wrong while I was trying to remove the program or is it just because the software is stubborn?

I just want it gone from my laptop and I need to find out how to make that happen.

Thanks for any help!

P.S. Using Macbook Pro is the closest community I could find for my problem, Sorry if this is the wrong area.

Edit: I got the icon off of my menu bar but I still see Drive Genius when I right-click files.
