ProPDFConverter Toolbar disrupts your browsing experience with intrusive ads
ProPDFConverter Toolbar travels as a browser extension which is offered on Chrome Web Store.
Developers of this tool try to lure people into using it by promising to provide quick PDF converting services. However, this potentially unwanted program can take over your regular browser and generate annoying ads or collect various information about its users.
Shortly after the installation, this questionable application alters your browser settings and sets itself as a default search provider. As a result, you can neither change the parameters to the previous stage nor eliminate the browser hijacker . Therefore, IT experts receive many complaints about the complexity of ProPDFConverter removal.
Besides, it can collect information about your browsing habits or data you manually provide to them. Furthermore, these details are used to deliver intrusive ads which correspond to your frequently visited pages or clicked content. Likewise, you are more likely to click on them and increase the pay-per-click revenue for the contrivers of Pro PDF Converter .
Our IT experts recommend you to remove ProPDFConverter as soon as possible. You can do that by employing or since they will quickly eliminate the browser hijacker from your system.

How ProPDFConverter Toolbar got into your browser
From our report of Dec 2017 · not reviewed since
Even though you can manually install ProPDFConverter extension from Chrome Web Store, it is also bundled together with freeware.
It helps the developers to distribute the potentially unwanted program stealthily since Quick or Recommended settings do not entirely disclose the information about the browser hijacker.
Likewise, people who choose those parameters and skip installation steps end up installing the PUP on their systems. However, you can avoid the browser hijackers by installing freeware with Advanced or Custom settings and unmarking any boxes which have been selected before.
Additionally, stay away from ads which might appear among the search results. They might also be programmed to start infiltrating malware automatically. The best option would be to use an antivirus system all the time in order to protect your PC from various threats.

ProPDFConverter removal can be easy
While manual ProPDFConverter removal is a complicated procedure, you can choose a better option — automatic elimination.
It only requires to download a security software to your computer and run a full system scan. Afterward, you will be free to use your PC without any annoying ads or redirects.
If you still opt to remove ProPDFConverter manually, make sure that you carefully follow the guide below. Experts from Udenvirus.dk note that any misinterpretations of the guidelines can harm your computer or damage OS permanently. Likewise, you should either possess specific IT knowledge or choose automatic elimination instead.
Questions about ProPDFConverter Toolbar
Is ProPDFConverter Toolbar a virus?
Most programs that appear the way ProPDFConverter Toolbar 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.
ProPDFConverter Toolbar came back after I uninstalled it. Why?
Something else is reinstalling it. Common causes are a second program from the same publisher, a scheduled task that downloads it again, or a browser extension that keeps prompting for it. Sort Installed apps by install date and uninstall each entry from the same day that you did not choose.
Then open Task Scheduler and look in the Task Scheduler Library for tasks with updater-style names that you do not recognise. Check Startup apps in Task Manager too. If ProPDFConverter Toolbar still returns, start Windows in Safe Mode, uninstall it there and run a Microsoft Defender offline scan, which looks for loaders that ordinary scans can miss.
Why can't I change my search engine back?
Because something keeps setting it. If an extension controls the search engine, Chrome and Edge show a note that an extension is controlling this setting, and your change is reverted. If a policy controls it, the field is greyed out and the browser shows Managed by your organization.
Remove the extension first, then the policies, and only then change the search engine; the change will stay. If it still reverts, look for a program in Installed apps or a scheduled task that reinstalls the extension.
What do I lose if I reset Chrome or Edge?
Less than you might think. A reset turns off all extensions, which you can turn back on one by one, restores the default search engine, home page, new tab and pinned tabs, and clears cookies, so you are signed out of most sites.
Bookmarks, history, saved passwords and autofill data stay. Firefox's equivalent, Refresh Firefox, keeps the same essentials but removes add-ons completely. Before you reset, make sure you know your main passwords or have them saved, since you will need to sign in again.
Is only one browser affected?
Often not. Programs that install hijackers tend to change every browser they find, and sync can carry the extension to other computers signed in to the same browser account. Check Chrome, Edge and Firefox, even the ones you rarely use, and look at the shortcut targets on the desktop and taskbar for each.
If you use sync, remove the extension while signed in so the removal syncs too. Also check the On startup setting and the new tab page, because hijackers change those as well as the search engine.
How did ProPDFConverter Toolbar get on my computer?
However, you can avoid the browser hijackers by installing freeware with Advanced or Custom settings and unmarking any boxes which have been selected before. Software of this kind often comes bundled with free programs, fake updates or downloads from unofficial sites.
It can also arrive through a browser extension or a notification you allowed on a spam page. Think back to what you installed or allowed just before the first ad or redirect appeared.
Will my antivirus detect ProPDFConverter Toolbar?
Not always, because our check found no Microsoft Defender detection name for it. Our check found no Microsoft Defender detection name for it, so a scan may not name it. Update the security program first, then run a full scan instead of a quick one.
Also scan with a second on-demand scanner, because one program can miss what another finds. A clean scan does not prove the signs are gone, so check the browser extensions and installed programs by hand too.
How do I stop the pop-ups and redirects from ProPDFConverter Toolbar?
Remove the program or extension that causes them, then block notifications and reset the browser. Signs our report lists: An unknown program in Installed apps. In Chrome open Settings, Privacy and security, Site settings, Notifications, and remove the site you do not know.
Check the extensions list and the installed programs list for anything you did not add. Restart the browser and test a few sites to see whether the ads are gone.
Will Fortect remove ProPDFConverter Toolbar?
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 ProPDFConverter Toolbar, 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.
