Pdf Converter Hub “Virus”

Keeping your computer safe from potential threats that may lurk on the Internet

One significant issue with hijackers in addition to the sheer irritation that they are capable of causing is the reliability (or lack thereof) of their advertising materials. It is no secret that many hijackers impose little to no control over what types of ads they spam on the users’ screens. This means that you may get shown all sorts of obscene, misleading, fake or deceitful ads. In some (though relatively rare) instances, a hijacker may generate adverts that are linked to obscure and/or potentially hazardous web addresses. It’s even possible that some of those online addresses are used for the distribution of different forms of malware and other dangerous programs – Ransomware, Spyware, Rootkits, Worms, Trojans and so on and so forth. As we said, these instances are still rather rare but it is of course better if you simply eliminate the cause behind the uncontrolled ads generation which, in this case, is Pdf Converter Hub. As we said, the guide from this page has all the info you will need to eliminate this potentially unwanted piece of software so be sure to give it a go if you need help with uninstalling Pdf Converter Hub.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

  • I saw on eBay a cheap (99 cent) pdf creator and am asking if this is one that has the bad features you write of.

    It is called PRO PDF STATION FULL EDITION, and has the following description “PDF Editor Creator Edit Viewer Converter Reader Software-Adobe Acrobat Alternate. Generate 100% industry-standard PDF and PDF/A files compatible with Adobe® Acrobat® that anyone can view, with any PDF reader, on virtually any device. 2019….”

    Is this the bad one?

    P.S. Can you recommend something cheap but safe that can do PDF/A and if possible work with “Adobe Scan” on my iPhone?
