It’s a well-known fact that Trojans like Viewdow are among the most serious types of online threats that web users may encounter. However, despite the widespread fear, the general public still doesn’t understand what makes these infections like Viewdow so dangerous.


People typically freak out and don’t know what to expect when they become infected by a program like Viewdow, which happens to be a Trojan horse. That’s why, in the next few paragraphs, we want to not only explain this malware but also provide a step-by-step guide that explains how to remove it. To help you get rid of Viewdow easily, we’ve also included a professional removal tool that can save you time and effort.

The Viewdow Virus

A threat like the Viewdow virus may give hackers access to your data and cause a host of other problems related to the malware’s intended function. Because of this, it’s next to impossible to know for sure what the Viewdow virus is doing on your computer.

What can the Trojans do?

Trojans are notoriously difficult to detect after they have infected a system, since they typically don’t exhibit any symptoms that can give them away. When they infect your PC, they may cause it to become slow, unresponsive, or crash often for no visible reason.

Trojan viruses are often used to steal information, which is one of their most dangerous uses. Threats like Viewdow may use a wide variety of methods to access the personal data stored on their victims’ computers. This includes your usernames and passwords for various social networking sites, online banking, shopping, and other accounts, as well as your credit card and other personal information. If a Trojan is intended to steal anything, it will find a way to do it. Aside from stealing data, a threat like Viewdow may also be set to wipe out certain files or perhaps the whole system.

Hackers often employ Trojans like Viewdow to spy on their victims. Once again, they may be seeking specific data, but this time it will most likely be linked to you as an individual, heightening the stakes significantly. They could listen in on you via your computer’s microphone and watch you on your webcam. With the use of keystroke logging and other methods like screen-sharing, threat actors may also hack your passwords, find out your physical location, see your online activity, and monitor any communication you may have locally or online.

Other ways of using a Trojan infection involve exploiting your computer’s resources for criminal activities such as spam or malware distribution. Also, Trojans may be configured to mine cryptocurrency on your computer and transfer it to the hackers. On top of that, viruses like Viewdow, Viewndow, Altruistic can act as a backdoor for other malicious software to enter your system.

It’s fortunate that you were able to identify Viewdow early on, because you can see that there are many ways in which this Trojan can cause damage, and none of them are particularly appealing. Now that you know what you are dealing with, it’s crucial that you remove Viewdow with the help of the guide below and learn to stay away from such infections in the future.

To avoid a close encounter with Trojans anytime soon, you must ensure that your computer is well protected against this and other types of malware. Here are some basic safety recommendations that you may want to follow:

  • Keep an up-to-date, high-quality antivirus application (AV) active at all times.
  • Always keep your system up-to-date and your Firewall enabled.
  • Don’t put off installing system updates when they become available.
  • Never forget to stay away from the obvious virus sources on the web. Sites for adults, torrent and file-sharing networks, and other similar sites that offer illegal content are common examples.
  • Spam emails are also a common source of malware, so use caution when opening them.

    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. If you see a screen like this when you click Uninstall, choose NO:





    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.

    • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

    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.



    Type Regedit in the windows search field and press Enter.

    Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

    • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
      HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
      HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
