Privacy Guardian (eyeball icon) is a feature in System Mechanic Ultimate Defense you also install as a web browser extension. (Privacy Guardian can also be purchased separately.)

Privacy Guardian blocks access to your sensitive online data, device info and habits whenever you use the internet. The desktop app features a dashboard that lets you manage all of your Privacy Guardian settings, view attempts to track you and more, all in one convenient place.

Privacy Guardian thwarts efforts to gain vast amounts of your personal information based on your search history, shopping habits and more.

Installing the Privacy Guardian browser extension

Before installing the Privacy Guardian browser extensions, first make sure that your web browsers are fully up-to-date. Second, the latest Windows updates should be fully applied.

PG Browsers 2

Even if you typically use just one web browser, it is recommended that you enable online privacy protection for each of your browsers. If you have not already been prompted by Privacy Guardian and therefore done so, to enable privacy protection for your browsers:

  • From the Privacy Guardian Dashboard, click Browsers.
  • Here you will see a list of browsers available for privacy protection.
  • Choose a browser from the list, and click Enable.
  • Follow the onscreen steps as Privacy Guardian walks you through adding the browser extension for the browser.
  • Moving down the list of available browsers, click Enable and follow the onscreen instructions for each subsequent browser.

Clear your browsing data

  • Open the My Tracks tab.
  • Click Clear data next to the browser(s) you wish to clear.
  • When the clearance settings box opens, click the boxes next to the items you wish to clear. Items with a red square will be cleared. Reading the description for each item may help you decide. Among the items you may select are cookies.
  • Note that these boxes begin as unchecked each time you go to clear your browsing data, to help prevent you from accidentally clearing data you wish to keep.
  • When you are finished deciding which browsing data to clear (including cookies), click Clear selected data now.
  • Click the red on the top right of the browser-clearance notification message to close it.
PG Clear Cookies
PG Whitelist sites

Turn off cookie clearance for specific websites

Some cookies are useful, e.g., by keeping you logged in to trusted websites or retaining your shopping cart orders. To whitelist certain websites from your scheduled or manual cookie clearance, follow these steps:

  • From the Privacy Guardian application Dashboard, click My Tracks.
  • On the right side of the window, click the Add or remove websites from whitelist button.
  • You may Choose from popular options if you are unsure which websites to whitelist.
  • Click within the box that says Enter URL to enter a specific website you have in mind.
  • Review your whitelisted sites in the box below this entry field.
  • Click Remove to re-enable cookie clearance for any given website in this list.
  • When you are finished making changes, click Done.

Once a computer is already infected with malware, Malware Killer (crosshairs icon) is the nuclear option you call upon to find and eradicate it. Malware Killer is the perfect complement to real-time protection, as it finds and eradicates malware when all else fails.

Scanning the system

To scan, click Scan system now and select how broadly or narrowly you wish to scan your computer. You can scan the entire system, or choose specific files or folders to scan.

ByePass (arrow icon) is a web browser extension that securely manages all your passwords across your devices, regardless of platform. ByePass features a remote universal logout function called Login Guardian that lets you log out of all websites from wherever you are.

ByePass also helps protect your online purchases by letting you encrypt and store credit cards that are only deployed as-needed when making online purchases, so hackers and keyloggers cannot steal them.

A similar local encryption feature for writing notes enables you to store sensitive info securely, such as PINs.

The ByePass browser extension is the main ByePass interface:

Adding the ByePass browser extension to your default web browser

This is the main ByePass interface and therefore a necessary step. ByePass currently supports Google Chrome, Mozilla Firefox, Apple Safari and Microsoft Edge.

  • Click Install ByePass.
  • Click Add extension. After you install the ByePass browser extension, click on the extension’s icon in your browser.
  • Click I agree, let’s start and then Create an account. Create your Master Password and complete the setup of your ByePass account.
  • It is best to use the email address associated with your purchase of System Mechanic Ultimate Defense. Be sure the email matches the one you just entered with your key on the Welcome to ByePass screen. Here you will also think up and enter a Master Password. This is the only password you must remember—it will be used to log into ByePass and manage all your encrypted passwords, secure notes and credit cards.
  • After logging into ByePass, you can begin creating and/or adding secure login credentials for your various online accounts, as well as encrypted credit cards and notes.

Using ByePass to securely store your passwords

When you first sign into ByePass, it should list for you suggested accounts that you’ll want to add. You can choose to have ByePass add all of these accounts at once, or you may click on an account such as Facebook, Twitter, Google or PayPal to add the account’s credentials to ByePass.

SS menu 2

The System Shield menu (shield icon) is a shortcut to the features of the real-time AV protection within System Mechanic Ultimate Defense. You can ensure real-time protection is enabled, view history and quarantined files and adjust settings like automatic virus definitions updates.

The Search and Recover menu (medic icon) lets you search for accidentally deleted files in order to try and recover them. You can point to a specific location you’d like to search, as well as determine the location you’d like recovered files to be saved to.

SR menu 2
DS menu 2

The DriveScrubber menu (scrub brush icon) allows you to select an entire hard drive to wipe, and set specifications for the precise wiping technique you prefer.

With all of these performance, protection and privacy products at your service, you’ll unleash the full power of your computer, as well as keep it in pristine condition for maximum longevity. However you use your modern Windows machine, System Mechanic Ultimate Defense is ready to take you places whenever you’re ready to go.

What is iolo's Whole Home License?

The Whole Home License® is iolo’s licensing policy that allows you to install and keep your software running on all of your compatible devices within the same home. Previously, users were allowed to install and license their iolo software simultaneously on a maximum of three PCs. Under the Whole Home License, a single activation key allows you to use your iolo software on all of your PCs, other than any PCs you use for business purposes. What you need to know about Whole Home Licensing

  • You, your spouse, and your relatives living within the same household may use the same license on any number of PCs that you own which are not used for business.
  • For full legal terms and conditions, see

To install your iolo product on additional PCs:

  1. On the additional computer, download the latest version of your iolo product. Choose from the list of downloads offered here.
  2. Follow the steps in the installation wizard, and enter the same Activation Key that you used to install on your original computer.

You can view the Activation Key on the original computer from within System Mechanic > red menu bar > key icon > Activation Key.
