IObit Reviews 

For now, I will rate the AdvancedSystemCare from Iobit at 4 stars.
Only 4 stars because Iobit likes to add other apps to the initial download, and if you're not paying attention, you won't realize what you're clicking "yes" to.
That said, my laptop was experiencing random mouse movements and windows opening and closing at will.
I downloaded Iobit AdvancedSystemCare. Ran multiple scans. Did the "fix" required, and my laptop's performance and speed has increased quite a bit. I have not experienced the random mouse or windows issue since.
So, for now...I believe Iobit did a good job.

,,IObit Software Updater,, :
You only update simple applications??? We download new versions of programs directly from the manufacturer!!! You don't do anything new !
Why don't you make a database with the latest Microsoft Updates for Windows-10 ???? Many people need it in the coming years, to download everything missing from Windows-10 !!!! Take care of this important issue, don't worry about $1 apps ! Wake up from your sleep !

This is an excellent company. It quickly addressed my issues, and then contacted me to make sure that I was happy with the solution. I was. No other company has ever done this! Best of all, these are excellent products and work very well.

I asked for a refund because they invited me to complete an order the previous evening, and they refunded me within a few days, even though I received about €2 less than I had spent.
Fees?

Had a problem with one of their problems and it was resolved immediately with an email solution.
However, (and I hope IObit read this) I may remove all of their software if the volume of ads to buy more of their apps does not slack off soon.

I regret ever installing IObit software. Not only did it fail to fix a single issue on my PC, but it also buried me in a flood of unwanted programs I never asked for. Every time I opened my computer, there was another useless pop-up or tool they shoved in without permission. The worst part? There’s no simple way to stop them unless you completely remove everything, which ended up taking me hours of cleanup.

Their support was absolutely no help. Instead of solving the problems, they tried to push even more of their junk onto me. I expected a tool that would improve my system, but instead I got the digital equivalent of a virus disguised as “optimization.”

Save yourself the headache and stay far away from IObit. There are plenty of trustworthy alternatives that don’t sneak in programs you never wanted and waste your time. I learned the hard way, but I’ll never let their software near my computer again.

Many thanks!
Yes, I downloaded and re-installed Smart Defrag 11,
this allowed me to register the software.

This response from IOBit regarding software registration, was prompt and in keeping with my overall experience with the company.

I've been using IOBit software for a number of years, on several different computers, with very good results.
Recommended!

I have purchased several iobit products over the years and have always found both them and their Technical Support First Class.

They make it extremely difficult to cancel subscription, also you can't login to your account, password reset links do not arrive in the mailbox. Definitely they are focused on scamming people and I don't want to support projects like that.

The first email the person refused to help me. I still have the email. I was ready to drop my 20+ years as a customer. And all my clients.

Great for updating drivers it is possible to repair USB bad driver.

VERY VERY HELPFUL AS WELL

Excellent program. Highly recommended. Especially when you buy a new computer and clone the old computer, a lot of mismatched drivers.

Also, very prompt follow up from the support.

I've always been satisfied with IObit products but their advertisements were always annoying. But what is really problematic is that lately they've completely removed their subscription management pages (which is illegal?) and made it very hard to cancel or turn off auto-renewal.

I had contact with the customer Service of IObit (and their Invoicing Partner Paddle.com) regarding a problem with an upcoming Invoice about an Upgrade of IObit-Products. The contact was very fast, teh feedback and handling about the issue was friendly and professional. Thank you for that good Service and customer relation.

I stopped using IObit Drive Booster when the blue screen of death appeared on my Windows 11 Laptop way back in 2023 after updating the drivers using IObit Drive Booster.

But as of 28th June 2025, to the time of writing the review, I decided to try IObit Drive Booster again after seeing on the IObit website that the software passed the Microsoft WHQL test.

I am officially back to using Drive Booster since, after updating the drivers, the blue screen of death didn't appear.

if you cant fix please refund

Consumer Review: A Closer Look at IObit’s Software and Business Practices
📆 Purchase Date: May 18, 2025
🛑 Refund Requested: June 19, 2025
________________________________________
Overview
On May 18, 2025, I purchased a bundled subscription from IObit via Paddle.com that included Advanced SystemCare 18 PRO, IObit Uninstaller PRO, and Driver Booster 12 PRO, licensed for 1 year on 3 PCs. These tools, on the surface, appear to offer powerful system optimization and maintenance solutions, and for a brief period, I found them to be incredibly effective. However, my experience took a dramatic turn, leading me to request a full refund and discontinue use just one month later.
________________________________________
The Issue: Embedded Spam and Persistent Marketing Pop-ups
Despite paying for a premium license, I found myself continually bombarded with aggressive, intrusive marketing pop-ups. These weren’t occasional reminders or optional alerts—they were hard-coded spam-like prompts that appeared every time I used the software, regardless of my configuration settings.
While IObit includes an alleged “option” in the settings menu to disable marketing notifications, this option proved to be completely ineffective. Even after toggling it off, the software continued to push ads for upgrades and unrelated third-party products. This strongly suggests that the marketing functions are embedded at a deeper level, beyond user control—what can best be described as built-in spam.
________________________________________
Ethical Concerns and Consumer Trust
As a consumer, I find this practice deeply offensive and unprofessional. It is one thing to offer a free product supported by ads. It is quite another to charge customers a subscription fee only to aggressively market additional services to them within a paid product. What makes this more troubling is the nature of the software itself—these are tools marketed as solutions for cleaning your PC, protecting against malware, and improving system performance.
The contradiction is glaring: the very software meant to protect users from pop-ups and unwanted ads is the same software inflicting those experiences on them.
This practice is not only unethical but also highly manipulative, and I believe it reflects a larger issue in the software industry—where user consent and control are often ignored in favor of profit-driven design.

Broader Patterns and User Complaints
My experience, unfortunately, is far from unique. Public sentiment around IObit confirms a growing concern:
• Trustpilot lists over 350 one-star reviews explicitly citing aggressive advertising and spam-like behavior in IObit’s software.
• On IObit’s own forums, users have posted over 500 complaints related to persistent pop-ups, bundled installations, and spam tactics—some dating back nearly a decade.
• On Reddit and other tech communities, IObit is frequently described using terms like "spamware," with users accusing the company of pushing fake errors and exaggerated alerts to drive unnecessary upgrades.
This pattern of user feedback paints a clear picture: IObit’s business practices are routinely called into question, and the volume of complaints suggests these issues are not isolated incidents but part of a systemic marketing strategy.
________________________________________
Final Thoughts
It is disheartening to abandon software that I genuinely found useful, especially since the tools themselves performed well from a technical standpoint. However, functionality cannot excuse manipulative marketing tactics, particularly when those tactics override user preferences and compromise user trust.
As consumers, our choices matter. If you have purchased IObit software and experienced similar issues, I encourage you to demand accountability—uninstall the software, request a refund, and make your experience known publicly.
Until IObit takes real steps to respect its paying customers by removing forced advertising from its premium products, I cannot recommend their services.
