A Trojan known as Viewndow is one of the most recent representatives of this malware family, and it has been infecting an increasing number of people. That’s why we wrote this post: to warn people about this danger.

The Viewndow Virus
A Trojan virus like Viewndow is unusually flexible when it comes to causing harm, which sets it apart from the bulk of other malware types. That’s why they’re preferred by most malicious actors on the internet. Depending on what the hackers who put Viewndow.exe on your computer want to achieve, a virus like this can do a number of things.
For example, Trojans like this one may easily erase certain files from your computer, or they can format all of your disks and drives, destroying everything that you store on them. It’s not hard to understand that, after such a data-destroying attack, your computer may become completely unusable.
Theft is another thing viruses like Viewndow are frequently used for. The virus may use a variety of techniques to obtain private information, such as financial data, or health status, professional details, and other company data that could be of interest to the criminals who are in control of the infection. For instance, Viewndow.exe may use a technique known as keystroke logging to record every keyboard key you hit. In this way, the malware may let criminals get their hands on your login information and access your social media, banking, and other accounts. Other, more complex methods of data theft, such as rerouting all of your traffic to the hackers’ servers, may give them control over everything you do online.
Spying on victims is another terrifying use of Trojans. All of the above methods of data theft can be used to spy on you in combination with accessing your camera and microphone and watching everything you do on your screen.
Your compromised computer might also be exploited as part of a botnet, potentially infecting other machines in its network and distributing spam. As a matter of fact, Trojans may frequently be used to introduce additional malware and viruses to the victim’s machine, most typically ransomware. Aside from that, the attackers could use the processing power of your computer to mine cryptocurrency for themselves.
As you can see, the things Viewndow may be up to on your computer are so diversified that there should be no question that its removal should be a priority. Our Viewndow removal guide can show you the steps to remove the infection, but if you’d rather put your trust in a tested removal program, we have that, too.
After you’ve removed the Trojan, you should pay more attention to system security and take every precaution possible to avoid other attacks in the future. You may accomplish this by avoiding all the possible sources of Trojan horse infections, such as spam emails and compromised websites. If you have to download something from the internet use only trusted download sites since torrents and other downloadable files may potentially surprise you with a concealed danger. You should also try to limit your interaction with internet advertisements, since, among them, there are often malvertisements used to spread viruses and other forms of malware.

Next, we recommend that you reboot the compromised computer in Safe Mode in order to run only the most essential processes and limit the malicious activity of Viewndow to some extent.
After that, when the system reboots, click on the Start menu button and type msconfig in the search field. Open the result and click on the Startup tab:
There you will see a list of startup items. The ones with a checkmark are set to start when the computer starts. Carefully check them and if you detect Viewndow or another entry that looks suspicious, and you believe it is malicious, remove its checkmark to disable it.
WARNING! READ CAREFULLY BEFORE PROCEEDING!
In the second step, you need to start the Task Manager and check what processes are currently running on the computer. To do that, press CTRL, SHIFT and ESC together and click on the Processes Tab. Next, filter the processes by CPU and Memory usage, and look at their names. If you detect a process that doesn’t look legitimate, has an odd name or uses a lot of resources, it is a good idea to check its files for malicious code by right-clicking on it and selecting Open File Location.
Next, you can scan the related files with a trusted antimalware software, or you can simply drag and drop them in the powerful free online virus scanner below:
If any of the scanned files turns out to be related to the Trojan infection or gets flagged as a threat, immediately end the process and delete the dangerous file and its folders.
You can check any suspicious-looking process in the Task Manager in this way until you are sure there is nothing dangerous running on the computer.
Next, use the Windows and R key combination to open a Run dialog box on the screen. In it, type appwiz.cpl and click OK.
In the new window that opens, search the list of programs for bogus apps or any recently installed pieces of software that might be linked to Viewndow. If you believe that a particular program is dangerous, or you can’t remember installing it, then it is a good idea to uninstall it from the computer with a right-click.
In case that a pop-up message like the one below asks you to confirm your action, when you click Uninstall, choose NO and complete the unisntallation process:
Trojans like Viewndow may often allow malicious actors to access important system files and make unauthorized changes in them. In case of hacking, the Hosts file of the computer may have some malicious IP addresses added to it. To check if such changes have been made in your Hosts file, copy this notepad %windir%/system32/Drivers/etc/hosts in the search bar of the Start menu and click OK:
Next, find Localhost in the text, and look for any suspicious-looking IP addresses like those on the image below:
If you see nothing unusual in your Hosts file, simply close it, but if you find some suspicious IPs below “Localhost“, please leave us a message with a copy of them in the comments.
Finally, to ensure that Viewndow.exe has been removed completely and there are no entries that can help it reinstall on the system, type Regedit in the windows search field and press Enter to open the Registry Editor.
Once the Editor screen opens, use CTRL and F key combination to open a Find box. Then, write the name of the Trojan in it and click on Find Next to search the registry for entries that are matching that name. If anything is found in the results, you should not leave it in the registry, but carefully delete it. Then, repeat the search as many times as needed until you delete everything that is related to Viewndow.
When you are done, use the left panel to manually navigate to the directories below:
- 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
Search each of them for files and folders that are named randomly or look suspicious, and if you believe they are linked to the Trojan infection, delete them as well.
Please note that deletions and changes in the registry may have a serious impact on the normal operation of your OS. If the instructions from this guide aren’t helpful in your case, or you are not sure which files are malicious and need to be deleted, please consider using the professional removal tool recommended on this page.

Viewndow is a harmful computer virus categorized as a Trojan Horse that can stealthily infiltrate your system and gain Administrative privileges without your knowledge. Threats like Viewndow.exe are usually distributed using pirated software, email attachments, misleading web ads, and harmful links.
Most users who get attacked by Viewndow do not realize when or how the infection occurred. This type of malware is known for its stealth and overall lack of symptoms. Of course, there are instances when some red flags may be present that indicate the system has been infected. High usage of system memory and CPU that could lead to unusual slow-downs in the computer’s performance is oftentimes associated with the attack from rogue software such as the Viewndow.exe Trojan. Also, more serious symptoms such as BSOD crashes, sudden screen freezes, and the unauthorized installation of unknown software are also possible indications that the system could be under attack. In such cases, checking the Task Manager to see if there are any questionable processes there and scanning your system with a reputable anti-malware program is highly recommended.
Viewndow can be very dangerous because it could be used for stealing personal data, spying on you, or even introducing more malware to your computer. The main reason threats like Viewndow.exe are so dangerous is their versatility and their unpredictable nature.
If the Viewndow virus infects you, it could be difficult to tell what exactly the virus would do next. It may simply use a portion of your RAM, CPU, and GPU to mine Bitcoins for its creators, but it could also introduce Ransomware to your system that could lock up all your data, or it may even directly spy on you through your camera and mic and then potentially use the footage for blackmailing purposes. Some Trojans are also capable of automatically sending out spam messages from the infected computer to other users, thus allowing the virus to propagate and spread. Regardless of the specific goal of Viewndow in your particular case, you should most definitely do everything you can to eliminate the threat, even if this includes reinstalling Windows as a last resort option.
To uninstall Viewndow, you must start by going to Apps & Features, checking the list of programs that may be related to the Trojan, and uninstalling them. Then you must also remove Viewndow entries from the Startup Items list, the Task Scheduler, and the Registry.
It’s also highly recommended to combine the manual steps of removing this Trojan with the help of a specialized anti-malware tool like the one you will see posted on the current page. Although it’s often possible to manually delete a Trojan Horse, this could be a very challenging task, especially for less experienced users, if the virus has entrenched itself deep within the system. One of the main challenges when dealing with a threat like Viewndow.exe is removing all of its Registry entries and doing this on your own could be not only difficult, but also potentially dangerous for your computer’s system, because there’s always the chance of mistakenly deleting something that you shouldn’t. That is why you ought to be really careful when removing Viewndow.exe, and it’s also why we recommend using a specialized removal tool.
