Mackeeper keeps asking for access to my confidential keychain information

Question

I recently updated my mackeeper account that was due for renewal and since doing so have been receiving the prompt below, about 5 times a day!!!!! After some research I decided to delete keychain from my apps, can anyone advice me on how to stop the prompts?
I asked mackeeper and I got this shady response: below (The reason I say shady is because my mac was doing some weird stuff until I uninstalled some adware stuff and I was not happy to go near it again)
They said:
- Download this adware removal script: http://www.thesafemac.com/downloads/TSMART.zip (You may want to search for an alternate solution, but this one worked satisfactory a number of times)
- Quit all running web browsers:
    1. Click on the Apple sign() at the upper left corner of the screen;
    2. Select 'Force quit...' from a drop-down menu;
    3. Look for: Safari, Google Chrome, Firefox (widely used browsers), click on their names one by one, and select Force quit.
- Open TSMART.zip and run the TSM Adware Removal tool script, follow on-screen recommendations;
- Restart your Mac: Click on the Apple sign() at the upper left corner of the screen and choose 'Restart...';
I'd also suggest you install either AdBlock or AdBlockPlus extension for your web browser (this will prevent many annoying commercials from popping-up): https://getadblock.com/ or https://adblockplus.org/
Please see more information about the ad-injection software on this Apple page: http://support.apple.com/en-us/HT203987

"MacKeeper" is a scam with only one useful feature: it deletes itself.
First, back up all data.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
If you have incompletely removed MacKeeper—for example, by dragging the application to the Trash and immediately emptying—then you'll have to reinstall it and start over.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
          Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the other functional components of the software will be deleted. Restart the computer and empty the Trash.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Let MacKeeper delete its other components before you empty the Trash.
☞ Don't try to drag MacKeeper from the Dock to the Trash. You must open the Applications folder as above.
☞ Don't try to remove MacKeeper while running in safe mode.
