The day I nearly gave up on my browser began just like any other remote work morning. I opened Chrome to join a video call, and within minutes, things went wrong.
-
A click on a search result sent me to a fake download page.
-
My CPU spiked to 90% while I only had email and a docs tab open.
-
A new coupon pop-up appeared on a site I’d visited a hundred times before.

Windows Defender scans were clean, and Chrome’s extension page looked normal. Nothing screamed, infected. That’s when I decided to stop guessing and let IObit Uninstaller properly audit my browsers.
My PC and Browsers Before I Started
This was my setup.
These were my baseline numbers;
-
Cold boot to usable desktop: 29 seconds
-
Idle CPU with Chrome open: 9–11%
-
In a 1080p shooter with Chrome minimized: 112 FPS average, 67 FPS 1% lows.
-
Browser issues: redirects, pop‑ups, and occasional tab hangs during meetings
I knew something in the browser layer was misbehaving, but I did not want to manually poke around the registry or hunt through every extension by hand.
Why I Looked Beyond Built‑In Tools?
Windows’ Apps & features is fine for basic program removal, but it doesn’t treat browser extensions or leftover components as a first-class problem. Defender protects me from a lot of file-based threats, but it didn’t flag the browser junk causing redirects and CPU spikes.
I’d used Revo Uninstaller before and still like it for desktop programs, but for this case, I wanted:
-
A view of browser plug‑ins and toolbars across Chrome, Edge, etc.
-
A way to auto‑flag malicious or ad extensions from a known database.
-
Leftover cleanup for files and entries that those extensions might have dropped.
According to the official page, IObit Uninstaller 15 Free is built to remove programs and Windows apps, and can also remove browser plug‑ins and toolbars, with an enlarged database that identifies more malicious plug‑ins on Chrome, Firefox, Edge, and Internet Explorer. It also offers Software Health to clean malicious software and browser extensions, as well as unnecessary setup files and hidden permissions.
That sounded exactly like the kind of first opinion I needed.
How I Set Up IObit Uninstaller for a Browser Deep‑Dive
I installed the latest IObit Uninstaller 15 Free, which supports Windows 11/10/8.1/8/7/Vista/XP. Before touching anything, I checked:
-
Chrome: 24 extensions enabled
-
Edge: 10 extensions enabled
-
Chrome idle CPU with my usual work layout: around 10%
Opening the browser extensions and plug‑ins view
From the sidebar, I opened the section that lists browser plug‑ins and toolbars. IObit Uninstaller groups items from major browsers in one place and uses its database to highlight potentially malicious or ad-related entries.
Seeing Chrome and Edge extensions side by side was already more helpful than jumping between each browser’s internal settings.
Sorting out the suspicious entries
I sorted extensions by name and user rating. That pulled a handful of items to the top that I either didn’t remember installing or that came bundled with other downloads.
Seven of them stood out:
I cross-checked where they lived and which browser they belonged to, then moved on to removal.
Removing the 12 Bad Extensions Step by Step
1. Uninstalling via IObit Uninstaller (not just Chrome/Edge)
Instead of only toggling them off in the browser, I removed those 12 entries with IObit Uninstaller, which is designed to completely remove browser plug‑ins and toolbars rather than just disabling them.
2. Letting the leftover scan clean their traces
After each batch removal, I let IObit Uninstaller run its deeper scan. The tool’s upgraded uninstall engine and Effortless Uninstall and Thorough Cleanup approach are super built to find all residual files, registry entries, and other junk that normal removal misses.
It found;
I confirmed the cleanup, which reduces background tasks and registry clutter tied to those extensions.
3. Using Real-Time Install Monitoring as a safety net
I always worry about what unwanted changes an installer might secretly make to my system. That’s why I rely on IObit Uninstaller’s Install Monitor feature. It works like a safety net: when I install a new program, Install Monitor runs in the background and actively detects every system change the installation makes — from added files and registry entries to modified settings. It logs all these changes for me.
Later, if I decide to uninstall that program, IObit Uninstaller knows exactly what was added, so it can remove everything completely, leaving no leftovers behind. In short, Install Monitor gives me full visibility into what an installation does, so I don’t have to guess or worry about hidden clutter.
What Changed After the Cleanup (With Data)
After cleaning the seven suspicious extensions and fixing Software Health issues, I re-measured:
-
Chrome idle CPU went from 6–7% instead of 9–11%
-
Cold boot to usable desktop stayed roughly the same (28 seconds)
-
Shooter game with Chrome minimized;
-
Before: 112 FPS average, 67 FPS 1% lows
-
After: 124 FPS average, 76 FPS 1% lows
On the browser side, the symptoms that started this whole thing dropped off:
-
No more sudden redirects to bogus update pages
-
Fewer surprise deal pop-ups on normal sites
-
Tabs stopped freezing randomly during video calls.
What I Liked and What Bugged Me
What I liked
-
Having Chrome and Edge extensions in a single list with trust indicators made it easier to spot trouble than clicking around each browser’s settings.
-
The leftover cleanup and Software Health scan gave me a more complete cleanup than disabling extensions one by one.
-
The small but real improvement in idle CPU and 1% lows made running a browser alongside games and remote work less risky.
What bugged me
-
Full scans (browser plug‑ins + Software Health) took a few minutes on my busy system, so I had to do them when I wasn’t in a rush.
-
The interface has several sections—Programs, Software Health, Browser extensions, and Install Monitor—so it took a bit of exploring to learn where everything was.
My Takeaway
I was thinking my browsers were a little messy, but mostly ok. But after using IObit Uninstaller — a dedicated uninstaller for Windows that goes far beyond just removing traditional programs — I found that 12 extensions were quietly causing redirects, CPU spikes, and other background issues. That was an eye-opener for me.
Now I make extension cleanup a regular part of my routine. If you use your browser for remote work or recording tutorials, having that extra control and visibility is well worth the few minutes it takes to clean things up.
