How Top Files Downloader ads got into your browser
From our report of Aug 2022 · not reviewed since
Usually, bogus browser extensions are spread on shady sites.
Crooks use social engineering methods to trick people into believing they are getting a good tool or sometimes the extensions are disguised as completely different programs. Most often users use unsafe download sources and unknowingly install something they did not intend to.
Apps that get listed there go through an extensive review process. However, you should still do your research - read the reviews, look at the ratings, and the number of users. It is best to pick plugins that have plenty of positive feedback and thousands of users.
Beware of claims that seem too good to be true. If an add-on is claiming that it can increase your download speed, it is false because the download speed depends on your Internet connection. You should also read the descriptions fully as fraudsters often make spelling and grammar mistakes.
How to remove Top Files Downloader ads
How to remove the Top Files Downloader extension
Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.
Step 1: Remove extensions you did not add
Top Files Downloader often works through an extension, so go through the extension list of each browser:
chrome://extensionsedge://extensions- Extensions and themes in Firefox
Switch suspicious extensions off one at a time and reload the page where the problem shows, then remove the one that stops it, and any other you did not add.
Remember the other browsers and profiles on the PC. If Remove is missing or greyed out, a policy forces the extension, which the policy step deals with. Windows 11 and Windows 10 show the same pages.
Chrome on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Uninstall Top Files Downloader
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10.
Sort the list by install date and find Top Files Downloader, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).
Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

Step 3: Reset the browser
Finish the browser part with a reset, which puts the search engine, start page, new tab page and site permissions back to their defaults and switches extensions off. Chrome: Settings > Reset settings > Restore settings to their original defaults.
Edge: Settings > Reset settings. Firefox: Help > More troubleshooting information > Refresh Firefox, which also removes its extensions. Your bookmarks and saved passwords are kept, and the menus are the same on Windows 11 and Windows 10.
Chrome on Windows 11: Settings > Reset settings. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 4: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Protect your privacy - employ a VPN

No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers - human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence.
In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

Freeware distribution platforms
It is not rare for people to look for applications to install for free which would normally cost money.
Many users like to use freeware distribution platforms. However, the owners of these sites often include additional programs in the installers that monetize user activity. You should always pay attention during the installation process.
Choose "Custom" or "Advanced" installation methods, read the Privacy Policy and Terms of Use. The most important is to check the file list and untick the boxes next to any unrelated applications. Even though it might get costly, you should always download apps from official sources. You may save in the long run by keeping your system secure and running smoothly.

Scan your system with anti-malware tools
If you completed all the previous steps but you still experience unwanted symptoms, you should check your system for other PUAs.
Manual removal of potentially unwanted programs can sometimes result in the renewal of the infection as users often fail to eliminate all the related files and entries. Besides, crooks often disguise them as "handy" tools so it can be difficult to identify them. If manual removal is what you still prefer, we have instructions for Windows and Mac machines:
To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:
- Enter Control Panel into Windows search box and hit Enter or click on the search result.
- Under Programs, select Uninstall a program.
- From the list, find the entry of the suspicious program.
- Right-click on the application and select Uninstall.
- If User Account Control shows up, click Yes.
- Wait till uninstallation process is complete and click OK.
- Click on Windows Start > Control Panel located on the right pane (if you are Windows XP user, click on Add/Remove Programs).
- In Control Panel, select Programs > Uninstall a program.
- Pick the unwanted application by clicking on it once.
- At the top, click Uninstall/Change.
- In the confirmation prompt, pick Yes.
- Click OK once the removal process is finished.
- From the menu bar, select Go > Applications.
- In the Applications folder, look for all related entries.
- Click on the app and drag it to Trash (or right-click and pick Move to Trash)
- Select Go > Go to Folder.
- Enter /Library/Application Support and click Go or press Enter.
- In the Application Support folder, look for any dubious entries and then delete them.
- Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.
Questions about Top Files Downloader ads
What is Top Files Downloader and why is it on my PC?
Top Files Downloader is a program that was installed on the PC, most likely together with something else you downloaded. Free software sites and many installers add extra programs on setup pages with pre-ticked boxes, so the extra install looks like your choice even though nobody read the page.
Check the install date in Settings, Apps, Installed apps: the program you installed that day is the probable carrier. If you do not need Top Files Downloader, uninstall it. If it belongs to your hardware or to a program you use, search its exact name and publisher first, because drivers and their tools can have unfamiliar names.
How do I stop programs like Top Files Downloader from being installed again?
Most unwanted programs arrive through installers, so the fix is in how you install software. Download programs from their official sites or the Microsoft Store, not from download portals or ads above search results. During setup, choose Custom or Advanced installation and untick every extra offer, including browsers, toolbars and optimizers.
Decline update prompts that appear inside other programs unless you know them. In Windows Security, turn on reputation-based protection and potentially unwanted app blocking. These steps would most likely have stopped Top Files Downloader before it reached the app list.
Why is my browser so slow since the ads started?
Each page now does extra work. An adware extension reads the page, decides where to put ads, loads them from ad servers and reports your visit, and that happens on every tab. Ad-supported programs add their own background activity.
Removing the extension or program usually makes the browser fast again at once. If it stays slow, open the browser's own task manager with Shift+Esc in Chrome or Edge and look for extensions using a lot of memory or processor time.
My scan found nothing, but the ads continue. Why?
Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.
Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.
Can an adware pop-up infect my PC just by appearing?
No. A pop-up, a notification or a new tab is only a web page or a message. It cannot run programs on Windows by itself, provided the browser and Windows are up to date. Infection needs a step from you:
- running a downloaded file
- installing an extension
- giving a stranger remote access
That is why scam pages work so hard to make you click. Close such pages with the tab's X or by closing the browser, not with buttons inside the page, which may start a download.
I let a "support technician" from an ad connect to my PC. What should I do?
Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.
Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.
If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.
Did Top Files Downloader collect my data?
Adware typically collects what it needs to choose ads:
- the sites you visit
- search terms
- approximate location
- browser and system details
Extensions with permission to read and change data on all websites can technically see everything on those pages, including forms. That is a privacy problem rather than proof of theft.
If you typed card details or passwords while it was active, changing the most important passwords is a reasonable precaution. Clearing cookies after removal ends the tracking sessions it may have started.
Do I need to reset my browser after removing Top Files Downloader?
A reset is a good last step, because it undoes settings that the program changed. A reset restores the home page, new tab page and default search engine, and turns off extensions.
It does not delete your bookmarks or saved passwords in the main browsers. Add back only the extensions you trust, one at a time.
Will Fortect remove Top Files Downloader?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Top Files Downloader, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
