Qdownloader – an online YouTube video downloading service that might infect your computer with malware

QdownloaderQdownloader is a video conversion website that might cause redirects to malicious websites

Qdownloader virus is a term used by users to describe malicious activity coming from a video downloading website qdownloader.io. Users are promised a service that allows them to convert and download videos from like YouTube, Instagram, Facebook, Twitter, and other popular websites. The lack of download button next to videos that are posted on these popular sites is what fuels these converting websites, and Qdownloader is just one of the thousands created, each benefiting from ad revenue.

While websites like Qdownloader might seem useful, it is important to know that they are often using unsafe affiliates and advertising networks, which results in frequent pop-ups, redirects, fake updates, and push notification prompts, as well as other unwanted content. At best, these ads can be annoying to deal with, and at worse, they could be the reason why users get infected with a Qdownloader virus, which can range from unwanted ads to such threats like ransomware.

Name Qdownloader or Online Video Downloader
Type Redirect virus, adware
Official websites qdownloader.io, qdownloader.net
Concerns
  • The service might be used to download copyrighted content such as TV shows, movies, or music
  • Site uses unsafe advertising networks
  • Redirects can lead to malware-laden sites
  • Fake Flash update prompts might make users install malware
  • Encountered scams might result in financial losses
Safety The safety of video conversion websites is typically low, as deceptive techniques and fake ads might be often used to make users download potentially unwanted programs or malware
Elimination The removal process of Qdownloader depends on the type of the infection (notifications can be eliminated via web browser settings; PUPs can be uninstalled manually; malware should be terminated with the help of powerful anti-malware program
Virus damage fix In case you got infected with malware, you should also employ PC repair tools such as ReimageIntego to get rid of the infection consequences (computer slowdowns, crashes, BSODs, lag, stuttering, etc.)

Qdownloader is one of many websites that allow users to download videos from YouTube and other sites (for example, Online Video Converter, Mp3hubFlvto, and many others). However, there is a reason why original websites do not provide download buttons – mainly because of copyright infringement policies. While listening to a music video for free is completely acceptable, downloading it on your phone would be illegal, as music is not generally free – the same goes for TV shows and movies.

As a result, many video converting sites such as the Qdownloader virus started being shut down, as many users download videos they are not supposed to. Nevertheless, the service itself is not illegal, as long as it is used to convert and download videos that are not copyrighted. In essence, the conversion service is similar to torrenting, and many websites, such as 1337x.to, exist to this day.

However, copyright is not the only issue that affects the Qdownloader website. As soon as you enter the URL of the video into the search bar, you will be immediately redirected several times to some other domain. In many cases, you will land on a site that asks you to enable notifications – various deception techniques are used, for example, the website asks you to press “Allow” and confirm that you are not a robot.

Eventually, you might land on a destination site that promotes unknown browser extensions or suspicious apps. We encountered the following message which promoted a well-known browser hijacker known as UpdateSearch:

Download Ready
FREE
UpdateSearch

By clicking the button below you will be prompted to install the UpdateSearch Chrome extension. By doing so, your browser's default search will be changed and will have access to UpdateSearch extension's functionality.

Download     Step 1

Please be aware that you should never download and install apps from such redirects, as you might end up infecting your machine with severe malware, such as ransomware. As a result, Qdownloader virus removal might be complicated, and it might also result in permanent personal file loss, sensitive information disclosure to cybercriminals, and other dangerous consequences.

In case you enabled notifications via one of the sites you got redirected to, you can remove Qdownloader ads and pop-ups by accessing the settings of your web browser – we explain how to do that below. Besides, if you interacted with the site in many different ways or downloaded something, you should also scan the machine with powerful anti-malware software and then utilize a repair program like ReimageIntego – it could help you get your computer up and running smoothly again after the infection.

Potentially unwanted programs and malware avoidance techniques

There is a huge misconception about the security of computers – users believe that infecting the device with PUPs or malware is almost impossible. Besides, the mentality of “if it happens to somebody else, it does not mean that it will happen to me” does not help at all. As a result, users neglect secure web browsing practices and security advice from experienced security researchers.[1]

To protect your machine from nasties, you should employ secure web browsing practices and automated tools that could help you to protect the computer from invisible threats. Many people believe that malware infection is always visible – it displays pop-ups, BSODs,[2] and other strange behavior. However, hackers are sophisticated individuals, and they write code that runs silently in the background without crashing the machine or disclosing its presence in other ways. As a result, your PC might be infected with a Trojan or other stealthy malware for weeks or months until it is discovered.

Thus, be attentive while you browse the internet and download new programs. If possible, always choose official download sources for the software and avoid third-parties. In case you insist on downloading apps from high-risk sites, you should always watch out for fake “Download” buttons, software bundle components (use “Advanced” settings instead of “Recommended” at all times) fake Flash update prompts or virus alerts, etc.

Finally, employ comprehensive security software that would repel potentially unwanted programs, malicious apps, and prevent access to malicious JavaScript sites[3] that are engineered to download malware automatically.

Get rid of Qdownloader virus  by following these instructions

As already mentioned above, Qdownloader removal differs, depending on your actions performed when visiting the website or converting videos. For future reference, we advise you to avoid websites that offer free video conversion services, as these sites can be dangerous and result in severe malware infection. In fact, there is a chance that your machine for infected with a silent malicious program that is running in the background without displaying any symptoms.

Thus, the first step to remove Qdownloader virus is to perform a full system scan with powerful anti-malware software. In case you installed potentially unwanted applications that belong to scareware or similar categories, a security tool would immediately flag them and eliminate them for you automatically. Besides, anti-virus will also check for invisible threats that would otherwise steal sensitive user data or install other malware on the device.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
