What is iolo System Mechanic Ultimate Defense?

iolo System Mechanic Ultimate Defense offers all of the features you’d expect in an antivirus program — real-time protection against malware, virus defense, and more — but it also goes above and beyond the offerings of many of its competitors.

The System Mechanic Ultimate Defense is almost like a swiss army knife for computer protection and performance. It offers a variety of tools that can help you keep your machine safe and running smoothly.

From removing malware and viruses and clearing unwanted files to give your computer a significant performance boost to managing your passwords and blocking 3rd party access to your data, System Mechanic Ultimate Defense makes it simple to optimize, restore, maintain, and protect your computer.


How Does System Mechanic Ultimate Defense Work?

The iolo System Mechanic Ultimate Defense helps clean up your PC and make it run smoother by removing malware, viruses, unused/unwanted files, and more.

There are a few different ways you can use the tool to do this:

Like other antivirus programs, System Mechanic Ultimate Defense can be set up to offer real-time, ongoing protection and system scans to ensure peak performance for your computer. This is the best way to ensure that your PC is always running at its best.

Manual scans

You also have the option to manually run scans. This is another way to give your PC an extra boost by running a scan that checks for malware, viruses, spyware, and other potential threats. A manual scan usually only takes less than a minute or so and will provide you with a quick look at any issues uncovered and recommendations for improving system performance.

Deep clean

A deep clean is a full-blown, in-depth scan into all the areas of your computer that normal scans don’t look at.

It goes through 7 different areas to find ways to improve the performance of your computer, looking at everything from your internet settings to improve browsing speed and Windows performance to security performance and memory resource optimization.

The deep clean process can take several minutes or longer, depending on the size of your computer, its age, issues your PC might have, and what you have installed on it.

Even though my computer is fairly new, the deep clean function uncovered a few different things that could be fixed or improved to help with performance.

It’s a good idea to run a deep clean scan at least once every few months to keep your system running smoothly.

System Mechanic Ultimate Defense also has a variety of privacy settings you can tweak to limit what Windows and other 3rd parties can see about your activity and data.

You can put these settings to be as light or intense as you feel comfortable with. There are even custom configurations available to let you pick and choose your preference to match your specific privacy goals.

Personally, I found the Standard recommended privacy setting to be just right for offering protection without limiting accessibility too much.

Password Manager

System Mechanic Ultimate Defense offers its own built-in password manager that not only helps you conveniently manage all of your different passwords in Chrome, Firefox, and/or Edge, but it also keeps your passwords and credit card data more secure and totally encrypted, keeping you from having to type this info into a browser where hackers can have access to it.

This tool uses true military-grade encryption to help avoid any password leaks or data breaches.

This is just another feature that puts System Mechanic Ultimate Defense above regular antivirus software, giving you that extra layer of protection.


How to Use System Mechanic Ultimate Defense

One of the things we liked about iolo’s tool is how easy it is to set up and use.

To get started, you just go to their website, pay for an annual license for the tool, download and install it, enter your product key information, and that’s it.

Once you finish all the steps as the program instructs you, your iolo System Mechanic Ultimate Defense should be installed and ready to improve your PC-user experience. 

The tool is super easy to use once it has been installed.

The interface of this software pretty straightforward and self-explanatory so even if you don’t consider yourself a tech person, you can easily make use of this powerful system optimization tool.

From the main screen, you have the option to turn on ActiveCare (highly recommended as this performs regular scans to keep your computer running optimally), do a manual scan, and fix any issues that need to be addressed.

On the left side of the interface, you can also go to your privacy settings, antivirus scans, password management tools, and overall settings.

For most users, there’s really not much of a need to tweak the settings too much. We found that the System Mechanic Ultimate Defense tool’s default “out of the box” settings were totally sufficient.
