This page aims to help you remove Onlinevideoconverter Virus. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows/Mac OSX.


Onlinevideoconverter is an unwanted software program which is designed to gather telemetry data from the user’s browser. Onlinevideoconverter watches the search queries, social media activity, and the site visits of the user after which it sells the info to internet advertisers.


The Onlinevideoconverter Virus will display pop up ads and messages.

Nowadays, it is pretty much impossible to go on the Internet an to not be greeted by all sorts of irritating, obstructive and invasive ads, banners, page-redirects, blinking boxes and so on. After all, ads earn a lot of money and who wouldn’t want to exploit that? However, it is one thing to have certain sites stream ads to your screen which ads go away as soon as you close the site and a whole other thing when there’s a constant influx of advertising materials targeted at your browsing screen regardless of what site you are currently visiting. In most cases, the cause behind this type of issue is an undesirable piece of software that has gotten on your PC and inside your browser. Such software pieces are normally referred to Adware or Browser Hijackers and they can typically affect any browser – Firefox, Chrome, IE, Opera, Edge as well as other less popular browsing options. In this particular write-up, we will focus on the Onlinevideoconverter Virus  adware app. This currently is a quite widespread software nuisance that many customers are complaining about since it seems to come out of nowhere on the users’ PCs and is also rather difficult to get rid of. The main reason for the unexpected appearance of Onlinevideoconverter Virus on the users’ computers has to do with the rather stealthy methods of distributing such apps (more on that, later in this article). As far as the removal of this adware piece is concerned, most users find it difficult to remove this app because it usually lacks an actual uninstallation feature and it’s also programmed in such a way so as to be difficult to remove from the “infected” machine. Now, we say “infected” but this isn’t really a proper term to use when talking about adware apps like Onlinevideoconverter Virus. In fact, software pieces like this one aren’t really all that hazardous and they lack the insidious and harmful abilities of threats such as Worms, Trojans, Viruses, Ransomware and Spyware. Still, given how irritating such an application could be, it’s only natural that you’d like to remove it from your PC in case it has gotten installed on it. This is what the following guide has been created for – to help you uninstall the nagging adware.

The Online Video Converter Virus

There, in fact, are couple more reasons why you might want to remove the Online Video Converter Virus in addition to its sheer ability to obstruct your browsing sessions and irritate you. Aside from being quite unpleasant, an app like this one could also be seen as a potential security hazard or vulnerability factor.

Now, there is no need to panic – as we said, this isn’t some Ransomware or Trojan Horse infection and will probably not initiate any harmful tasks on your computer. However, it really isn’t beneficial for your computer’s safety to have a software component on it that floods your screen with all kinds of ads, many of which might have questionable and maybe even unsafe sources. You surely wouldn’t want to get redirected to some obscure and shady website after accidentally clicking on some misleading advert that’s been brought to your screen by Onlinevideoconverter . However, even if you try your best to avoid interaction with the different pop-ups, page redirects and banners, you could still end up clicking on some of them without really wanting it as they could be really intrusive and obstructive. That is why, the better option here is to simply ensure that the source of the advertising disruptions is no longer present on your PC by making use of the manual steps from the removal guide or of the automatic malware-removal program that’s been added to it.

What you need to know about adware distribution

Naturally, few users would actually go out of their way to install an app like Onlinevideoconverter , especially if they are aware of its rather unpleasant capabilities. However, if the unwanted software component gets added to some attractive online offer, to a spam message or to the installer of some other piece of software, the chances of the adware getting inside the computers of more users would then go up. For instance, if you agree to install some app suggested to you by some obscure site or if you open some spam e-mail and download its attachment, you could easily end up with an adware program on your computer. The same could (and oftentimes does) happen if you install a new program through its Default setup configuration. This is the reason why it’s important you always opt for the Advanced setup menus that give you more information about any bonus software elements that might have bundled with the main thing as well as the option to leave them out of the installation if you don’t like them and if you wouldn’t want have them on your computer.

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:

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:

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



  • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.
