Constant blank pop-ups or redirects, and ads, a browser that won’t stop begging you to click “Allow”, or weird malware warnings from AVs that aren’t even installed on your PC are all signs of a browser hijacker. This is a rogue software (or sometimes even just rogue sites), and in this post, we’ll focus on one of the latest examples called Files-storage.cc.
Like Memory-scanner.cc, Indeanapolice.cc, and other similar annoyances, let we first explain what this Files-storage.cc window “appear” to be showing.
We tested that SpyHunter successfully removes Files-storage.cc* and we recommend using it. It will block Files-storage.cc from reinstalling itself and it will make sure your device is clean from any malware.

OFFERThere are servers called “C2s (command-and-control servers)”. These act as central hubs that cybercriminals use to remotely manage compromised devices on a network.
Attackers use C2 infrastructure to send instructions to malware-infected systems – like downloading additional payloads or exfiltrating data – and to receive status updates or stolen information in return.
That’s concerning, because it can be a sign your device has been infected with malware.
If a device is compromised, criminals may be able to use it for a wide range of activity, such as:
– Cryptocurrency mining
– DDoS attacks (flooding a website with traffic so it becomes unavailable)
In this case, it “appears” the activity may be associated with Lumma Stealer (an information-stealing malware).
Files-storage.cc it’s a tour guide to scams, phishing forms, and malware downloads. In other words, you don’t want it on your PC, which is why we’ve prepared an in-depth guide that will help you manually eliminate it.
But if you prefer a quicker, safer, and more streamlined solution that won’t take an hour or more of your time, we recommend SpyHunter 5, which is excellent at dealing with both hijackers and other, worse types of malware.
Step-by-Step Browser Hijacker Removal Guide
Follow the items in sequence and write down what you disable or remove so you can roll back a change if something you rely on stops working. This steady process removes Files-storage.cc, reduces recurring pop-ups, and helps you avoid accidental edits while you restore normal search, new tab, and permission behavior.
Quick Checks to Reverse Browser Changes
- 1.1Open your browser’s Settings and start undoing changes linked to Files-storage.cc.
In Chrome, select the ⋮ menu in the upper-right; in Firefox, use the ≡ menu for similar controls.
Open Extensions or Add-ons, review every entry, and flag anything you don’t recognize. - 1.2Review each add-on by its name, icon, requested permissions, and the full description.
If the details are vague, mismatched, or don’t fit your browsing needs, choose Remove.
When unsure, search the exact “extension name” to confirm the publisher and user reports. - 1.3Open Privacy and security, then go to Site permissions.
Review which sites can use your microphone, camera, location, and notifications.
Revoke access you don’t remember approving and keep only a short allowlist for features you actively use. - 1.4Still under Site permissions, remove entries you never meant to allow.
This reduces repeat prompts, noisy alerts, and surprise redirects on startup.
When done, restart the browser so the changes apply, then confirm the unwanted behavior doesn’t return.
If pop-ups and redirects stop after this pass, you likely removed the immediate trigger. If they persist, a policy may still be restoring changes at startup. Continue with the next sections to find and remove leftovers without broad configuration resets.

How to Remove a Browser Hijacker Manually
When the browser shows “Managed by your organization,” startup policies are enforcing key options, so a reset usually won’t clear them. The next checks help you uncover the entries that allow Files-storage.cc to reapply settings. Move carefully, verify each change, and keep brief notes to review after restarting Windows.
1. Identify Which Files-storage.cc Browser Policies Are Applied
- 1.1
Open the built-in policy page to list rules that Files-storage.cc may have put in place.
In Chrome: chrome://policy
In Edge: edge://policy
Let entries load, then review unknown items; use Reload policies to refresh or export for later checks. - 1.2Review each policy and watch for random-looking identifiers or unusual values.
Write down questionable entries so you can match them to folders or extension IDs later.
Record the exact policy Name and Value; these often map to storage paths or keys you’ll remove. - 1.3Open the browser’s Extensions page and enable Developer mode.
This view reveals extension IDs and install paths needed for manual cleanup.
Copy each suspicious ID into a text file so you can match it to folders on disk. - 1.4If Extensions won’t open or is greyed out, switch to File Explorer.
Working inside profile folders lets you continue even when the interface is blocked.
Enable View > Show > Hidden items so the AppData directories are visible. - 1.5
Use File Explorer to open:
C:\Users[Your Username]\AppData\Local\Google\Chrome\User Data\Default\Extensions
Each subfolder name is an extension ID; match these with your notes, avoid deleting folders you recognize as legitimate, and make a quick desktop backup before removal. - 1.6
In other Chromium-based browsers (e.g., Brave, Opera), extensions are stored under a similar AppData path.
Confirm the extension ID and location before deleting any folder tied to an unwanted add-on.
Open the browser’s About page to ensure it’s fully closed so files unlock for removal. - 1.7After deleting the suspicious folder, return to Extensions with Developer mode still enabled.
Confirm the extension no longer appears; if it does, repeat the cleanup and look for remaining files that could restore it.
Click Update in Developer mode to refresh the list and spot stealth reinstalls.
Remove Enforced Browser Policies from Windows
Some enforced browser controls are stored in the Windows Registry, and careless edits can destabilize a system. Focus only on keys that clearly match the policy names or extension IDs you recorded, especially ones connected to Files-storage.cc. This removes policy hooks that survive resets while keeping Windows stable.
2. Remove Policy Keys from the Registry
- 2.1Press Win + R, type regedit, then press Enter to open Registry Editor and start tracing policy keys connected to Files-storage.cc.
Before changing anything, open File > Export to create a full registry backup.
Choose All under Export range and save the file in Documents or another easy location. - 2.2Use Ctrl + F or Edit > Find to search for recorded policy names or extension IDs.
Select Find Next and delete only exact matches that unmistakably belong to the unwanted changes.
Press F3 repeatedly until no related values remain under HKCU and HKLM. - 2.3
If a key refuses deletion, right-click it, choose Permissions, then Advanced.
Under Owner, select Change, type Everyone, click Check Names, and confirm with OK.
Grant Full Control to Administrators and Users so the key and subkeys can be removed. - 2.4
After changing ownership, enable Replace owner on subcontainers and objects and Replace all child object permission entries.
Click Apply, then OK, Reboot, and check whether the Managed by your organization banner remains.
If it’s gone, open regedit again and repeat searches to confirm no related values have returned.
A background service, scheduled task, or local policy can quietly restore settings after you fix them. Use the focused checks below to remove components tied to Files-storage.cc without broad system changes. These are most useful if the managed banner or forced preferences return after a reboot.
Alternative Ways to Clear Enforced Browser Policies
3. Extra Methods to Remove Files-storage.cc Policy Enforcement
- 3.1
Open Local Group Policy Editor (Win + S → Edit Group Policy) and review rules that may have been added.
Expand Administrative Templates in both Computer Configuration and User Configuration to cover machine and user scopes. - 3.2
Right-click Administrative Templates → Add/Remove Templates.
Remove items you never installed, then browse Windows Components → Microsoft Edge or Google Chrome and set suspicious entries to Not Configured. - 3.3On Chrome, a utility like Chrome Policy Remover can help reveal hidden policy folders.
Download only from a trusted source, run it as administrator, then revisit chrome://policy and click Reload policies to confirm the list is clean. - 3.4Open Task Scheduler → Task Scheduler Library and remove tasks that launch unknown scripts, CMD/PowerShell, or policy loaders at logon.
Then check Services for recent entries from unfamiliar publishers and disable/remove them only when clearly linked to the unwanted changes.
Clean Up Files-storage.cc in Chrome, Edge, and Other Browsers
Profiles, sync, and cached data can quietly reapply altered settings. To prevent Files-storage.cc from returning after restarts or sign-ins, lock in your defaults and permissions. The steps below confirm that search, site access, and extensions stay consistent.
4. Remove Leftover Files-storage.cc Changes Inside Your Browser
- 4.1Open Extensions/Add-ons again and remove any item tied to Files-storage.cc or clearly out of place.
Use built-in pages like chrome://extensions to avoid themed views that might hide entries. - 4.2
