Is Online Document Converters ads dangerous?
From our report of Sep 2022 · not reviewed since
Online Document Converters is a browser extension with adware capabilities
Online Document Converters is a dubious browser extension used by crooks to generate revenue.
It is promoted as a handy tool that can convert files quickly and easily. Instead, it acts as adware and causes an increased amount of commercial content, like pop-ups, banners, and redirects.
Unfortunately, fraudsters may use rogue advertising networks that place ads leading to dangerous websites. As a result, people can end up on scam pages that try to trick them into providing personal information, downloading PUPs (potentially unwanted programs), and even malware.
Although the name and the advertising of the plugin insinuate that it should help convert documents, there are no such functions. There is no reason to keep this application installed on your machine, especially because it raises many user privacy and security concerns.

Use only official app stores
Crooks use multiple channels to spread their applications.
However, most of the time people get infected with bogus extensions through fake downloader pages or "official" promotional websites created by fraudsters. There, they boast about all the non-existent functions and try to convince users to press the "Download" button.
That is why it is best to use official app stores. Apps that get listed there, have to go through an extensive review process. However, users should be responsible for their own security and always do their research - read the reviews look at the ratings, and the number of users.
In some cases, apps like Online Document Converters can appear without the users' knowledge. That can happen when using freeware distribution platforms. They include additional programs in the installers and do not disclose it clearly. You should pay attention during the installation process.
Always choose the "Custom" or "Advanced" installation methods, read the Privacy Policy and Terms of Use. The most important step is to check the file list and untick the boxes next to any unrelated applications. Even though you may see prompts that state the additional programs are useful - pay no mind to it as most of them are designed to monetize user activity.

How to remove Online Document Converters ads
How to remove the Online Document Converters 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
Online Document Converters 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 Online Document Converters
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10.
Sort the list by install date and find Online Document Converters, 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.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.
One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.
However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable.
Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:
- power cuts
- Blue Screen of Death errors
- hardware failures
- crypto-malware attack
- even accidental deletion
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.

Protect your privacy
Protecting your privacy while browsing the web is very important.
One of the ways you can do that is by clearing cookies and cache regularly. Cookies are small data files that can store information such as your IP address, websites you visit, links you click on, and things you purchase online.
Normally, websites and web-based applications use this data to personalize the user experience. However, it can be used by crooks to make a profit by selling it to advertising networks and other third parties.
Besides, this powerful software can also fix various system errors, BSODs, corrupted files, and registry issues, which is especially helpful after a virus infection.

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 Online Document Converters ads
Is Online Document Converters a virus?
Most programs that appear the way Online Document Converters did are not viruses in the strict sense. They are potentially unwanted programs:
- real software that arrives bundled with other downloads and then shows offers
- changes browser settings
- starts with Windows
Some are harmless, some are annoying and a few carry adware. What makes it worth removing is that you did not choose it.
Uninstall it from Installed apps and check the startup list and the browsers for anything added the same day. If it refuses to uninstall or returns after a restart, treat it as more serious and run a Microsoft Defender offline scan.
How do I stop programs like Online Document Converters 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 Online Document Converters before it reached the app list.
Did Online Document Converters 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.
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.
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.
Do I need to reset my browser after removing Online Document Converters?
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 Online Document Converters?
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 Online Document Converters, 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.
