2. System Mechanic Ultimate Defense: All Features Analyzed!

Let’s get to the nitty-gritty of my System Mechanic Ultimate Defense review. Right off the bat, I’ll walk you through all of its features to see what you can expect from this robust and functional suite of tools.

2.1 System Mechanic

The feature I like the most is System Mechanic. It lets you scan the entire computer for certain issues, thus, determining your system status. For example, upon testing my computer for the first time, my system status was Critical, which you can see below.

System Mechanic Ultimate System Mechanic

System Mechanic showed my HDD space, system memory, as well as startup programs and running programs. Much to my surprise, I had 10 unknown programs running in the background, plus 12 unnecessary programs.

Clicking on the “Repair All“ button, I managed to fix all of these issues, bringing my system status to “Good.“

In the process, System Mechanic clean my junk files, repaired some security items, and shut down unnecessary processes slowing down my computer. Needless to say, I’m impressed with how well and smooth it worked, without “hijacking“ my computer resources at all.

Additionally, in System Mechanic, you can enable Automatic PC Maintenance. In this case, System Mechanic Ultimate Defense will do everything for you, without you having to fiddle around with settings. You’ll just get a notification of when it’s done, leaving you to enjoy your PC to the fullest.

2.2 Privacy Guardian

In this System Mechanic Ultimate Defense review, I must address this Privacy Guardian feature. Perhaps one of my favorites.

This feature is all about preserving your online privacy by preventing tracking and collecting personal information. Many sites you visit are known for these practices but System Mechanic Ultimate Defense can remedy this issue.

System Mechanic Ultimate Privacy Guardian

By clicking on Maximize Privacy, you’ll disable Windows tracking, and website logging, and clear your privacy items. However, I like the addition of a Whitelist where you can add the websites you want to exclude from Privacy Guardian.

Although, I personally don’t recommend doing so, given that pretty much all websites use cookies and store some information about you.

2.3 ByePass

Another feature I found useful is called ByePass. However, ByePass is a Chrome/Firefox extension that you can install once you activate your System Mechanic Ultimate Defense account. By doing so, you’ll get an excellent password manager that also serves as a password protector.

System Mechanic Ultimate ByePass

You can use ByePass to store passwords for every social media account or perhaps, use the extension to add useful notes. Moreover, I like the ability to safely store credit card and PayPal information to avoid typos when making purchases online.

Finally, I want to mention ByePass’ ability to generate secure passwords. You can choose how many characters you want, as well as generate easy-to-type passwords to make your life easier. This, accompanied by comprehensive security reports, makes ByePass a very capable addition.

System Mechanic Ultimate ByePass 2

Mind you, this addition is available only for Chrome and Firefox browsers, so you can’t use it on mobile devices. But that’s not a problem given how well ByePass works. Once I added my passwords, I never had to type them in again, making the entire log-in process a breeze!

2.4 Malware Killer

System Mechanic Ultimate Defense offers a tool called Malware Killer. As its name implies, it’s here to slay and devour malware attacking your computer effortlessly. You can do so through a scan that you can perform on several levels.

System Mechanic Ultimate Malware Killer

Here, you can scan system files, all drives, a specific file, a specific folder, or configure Malware Killer settings. I appreciate the variety in these settings, as you don’t need to perform a long scan to check out suspicious files.

System Mechanic Ultimate Malware Killer 2

Instead, you can scan files separately and see if your suspicions are justified. Furthermore, you can add exceptions as well, just in case Malware Killer mistakes a particular file for malware. Once you exclude the file, Malware Killer won’t deem it malicious anymore.

2.5 Antivirus

Malware and viruses aren’t the same. Viruses are much more dangerous and they can take the form of a Windows process that can slowly but surely bring your PC to a screeching halt. System Mechanic Ultimate Defense’s solution is rather efficient here.

It has Antivirus that works flawlessly, eliminating viruses with 99% efficiency. This feature is called System Shield and allows you to perform a full scan on a system level to determine whether or not you have potential threats.

System Mechanic Ultimate Antivirus

What’s more, System Shield can be updated with new viruses and spyware definitions, making sure that it’s up to date with new and dangerous threats. I personally like turning on real-time protection and automatic updates so that I don’t have to scan my computer every day.

In this environment, System Mechanic Ultimate Defense will do everything for you. Which, in the end, is the whole point of a security suite like this.

2.6 Search and Recover

My System Mechanic Ultimate Defense review wouldn’t be complete without the feature called Search and Recover. I found it extremely useful for recovering deleted files or files I accidentally moved to another location.

System Mechanic Ultimate Search and Recover

Search and Recover works rather simply. You just define the search location and choose where you want to save recovered files. Then, you can use SmartScan to eliminate junk files from search results, but also StrongScan for more in-depth search results.

Albeit, enabling the latter significantly increases search time, so it’s good if you’re not in a hurry.

2.7 Drive Scrubber

Lastly, let’s talk about Drive Scrubber. Its name says it all but for those who are oblivious, Drive Scrubber is here to scrub your drive – clear now? In other words, this feature can wipe the hard drive you choose if you want to format it or simply throw it away for any reason.

System Mechanic Ultimate Drive Scrubber

iolo, the company behind this software, claims that the deletion is military-grade, which means that every byte of data is wiped from the hard drive you choose. After it’s done, the information is permanently deleted and the drive is ready for disposal or another use.

Beware that this doesn’t work only on hard drives. Instead, you can use it on portable drives like a flash drive, camera storage, SD cards, etc, etc. Also, it will work only on drives where Windows isn’t installed, for obvious reasons.

3. Ease of Use and Device Support

When talking about device support, iolo limited System Mechanic Ultimate Defense to one platform – Windows. Thus, if you use macOS or Linux, you might need to go for another option because this one won’t work.

The good thing is that iolo took its time to develop a nice and bug-free app. I mean, you already saw that it looks really good, with all of the features lined up on the left for easier access. Each feature has sub-menus and additional settings that I found easy to access, too.

System Mechanic Ultimate Ease of Use

I also appreciate its descriptions. Each feature has its explanation, telling you what it is and how it works. This way, if you’re a newcomer, you’ll still know what to do, so you won’t need to wander around the app like you’re lost in the jungle.

Perhaps the best thing about System Mechanic Ultimate Defense is that you can do everything with a single mouse click. Wanna scan for malware? Use the blue button. Wanna wipe your hard drive? Use the blue button! Wanna optimize your PC and eliminate junk files?

Again – use the blue button!

System Mechanic Ultimate Ease of Use 2

Clicking on the gear icon opens up the Settings menu where you can additionally customize the app and its features. However, I find this Settings menu a bit cluttered and complex compared to the app interface, so I don’t suggest fiddling around if you don’t know what you’re doing.

The app is also available in several languages, so you can change the language at the top of the Settings menu. Therefore, if you find English a bit less understandable, you can change the app language to French, Spanish, German, and a few other languages.

4. Customer Support

iolo does a great job at providing round-the-clock support. Apart from live chat, you can contact the company via email or even using a phone number on the site. The number isn’t toll-free, so if you’re located outside of California where it’s based, don’t be surprised by an expensive phone bill.

System Mechanic Ultimate Support

Nevertheless, that’s not all. iolo offers a comprehensive knowledge base and a huge FAQ section to make sure you can fix the potential issues without going out of your way to contact them.

5. Pricing: Is It Affordable?

iolo offers a plethora of security products for your devices. System Mechanic Ultimate Defense is their most popular product but also the most expensive one, given its complex combination of various security features.

System Mechanic Ultimate Defense is the highest tier of System Mechanic and at the time of writing this review, it costs $23.98 a year with the 70% discount, which is a very good offer.

system mechanic ultimate defense pricing

The whole range starts with the aforementioned System Mechanic. It’s a cut-down version of the package I reviewed today but it also starts at $14.98 a year.

system mechanic pro pricing

On the other side, System Mechanic Pro costs $20.98 a year and it sits between Ultimate Defense and the starter plan comfortably. Although, for a small price difference between Ultimate Defense and Pro, I recommend the first option because it’s more feature-rich.

Lastly, a 30-day money-back guarantee is here as well, so in the case of dissatisfaction, you can claim your refund.

6.2 How to use System Mechanic Ultimate Defense on my Mac computer?

Sadly, you can’t use System Mechanic Ultimate Defense on macOS. At the time of reviewing it, System Mechanic Ultimate Defense and all of its versions are available only on Windows.

6.3 Can System Mechanic Ultimate Defense accelerate my internet?

1 thought on “iolo System Mechanic Ultimate Defense Review”

  1. Great review. I’ve also been a long time user, beginning with System Mechanic Professional, many years ago. After getting frustrated with Norton Utilities (after Peter Norton sold out to Symantec) and having to create, what I considered should’ve been optionally required, a “Norton Account” prior to installing, I decided to look around.
    After several reviews, and having “Trialed” a couple of the front runners, I settled on System Mechanic Professional. Over the years they’ve steadily “upped their game” with additional tweaks, increasing the “Licensing” from 3 PC’s to the current “Whole House” licensing (I’ve got an acquaintance who’s covering 3 Desktop PC’s and 4 Laptop PC’s under the same CD-Key). I would strongly recommend against the “Automatic Renewal”, as they have yet to fail with “Early Renewal”, “Black Friday” and other deep discount offers. I’ve been able to get “Renewal Discount” codes for 60%, 70% and even $9.95 (Black Friday) that, if you copy/paste the code for a “New Purchase” as opposed to a renewal. It makes for a handy “Extra License” for a friend or family member that you don’t want to share your license with. Simply download the “Free Trial”, and after installation, select the “I have an Activation Code”.
    Blessings to All
