Danger level 3
Type: Potentially Unwanted Application


ProPDFConverter is yet another version an already existing questionable browser extension called ConvertDocsOnline Toolbar. These two are very similar and both came from the very same creator, the notorious Mindspark Interactive Network, Inc. This family of useless and potentially unreliable toolbars has given us over a hundred tools over the past years, including HoroscopeBuddy Toolbar, GetFreeGifs Toolbar, and HolidayPhotoEdit Toolbar. Since this new toolbar does not mean direct threat to you or to your system, we have labeled it as a potentially unwanted program (PUP). But we still believe that you should actually take it seriously if you find this browser extension in your browsers. This PUP may present to you questionable third-party advertisements and sponsored links, for example, via modified search results. It may also enter your system along with malware infections. No wonder why we suggest that you remove ProPDFConverter as soon as possible.

Just like all its siblings, this new PUP also has its official channels to spread, such as the promotional webpage at and the Chrome web store at We must warn you at this point that if your computer is protected by up-to-date security software, you cannot even load the official page in your browser properly as it gets flagged and blocked, which is obviously not a sign of reliability. As a matter of fact, this should already be enough for you to want to delete ProPDFConverter if you have already installed it. But we have more on this useless tool.

Unfortunately, we have also found that this PUP may use alternative channels, which means more deceptive ways to spread. For example, you may click on corrupt third-party pop-up ads while browsing the net and landing on suspicious pages. Such a pop-up may claim that you need to install a certain software update or a plugin to be able to view content on the page or so that you can leave that page at all. In other words, you may be pushed to click on this pop-up, which may result in your installing this questionable toolbar directly. It only gets worse when you drop a whole freeware bundle with a click since that may contain a number of PUPs and malware infections as well.

You can infect your computer with such a bundle when, for example, you download free programs from shady torrent or freeware pages. These sites usually promote harmful software packages. So be prepared when you want to download a software crack or a keygenerator because you may infect your computer with all kinds of threats, including Trojans, adware programs, browser hijackers, fake alerts, and more. This is why we suggest that after you delete ProPDFConverter from your system, you scan your PC with a reliable malware scanner to see what you are up against.

This new PUP offers you document conversions and easy access to popular websites as well as the usual unreliable search engine. While you may actually be able to convert your .doc files to .pdf just fine, you should not trust this tool at all. If you were to use its search engine,, you would find yourself on a modified Google search results page that could include questionable third-party ads and links promoted by this PUP. Clearly, this is the only way for it to make money for its creators. However, these third parties could be sometimes unreliable. This simply means that you may click on ads or links that may open new tabs with malicious content or drop infections directly onto your machine. When you are taken to a malicious page, chances are cyber crooks will try to scam you. This can end very badly for you as you might share your personal as well as your banking details with criminals. If you do not want to lose money from your bank account or end up with more infections on board, we advise you to take action and remove ProPDFConverter as soon as possible.

This PUP may affect three of your main browsers, including Internet Explorer, Mozilla Firefox, and Google Chrome. If you find it in Explorer, you need to use the uninstaller you can find in your installed programs list in Control Panel. Unfortunately, using this uninstaller only takes care of Explorer. Therefore, you need to manually reset the other two browsers. Please follow our instructions below this article if you need assistance. Hopefully, you see now why it may be important for you to protect your PC more efficiently by installing a reliable malware removal tool like SpyHunter.
