What is Presenoker virus?

Presenoker virus detection indicates that the program installs and manages content without users' consent

Presenoker virusPresenoker virus is a dangerous infection that can run unwanted tasks in the background or infect the machine with additional malware.

Presenoker might be flagged by your security software on a Windows computer seemingly out of nowhere. Many users were surprised that they did, as the file pointed by the antivirus was located in legitimate application locations, such as NordVPN.

While in this case, the detection is likely to be a false positive,[1] the flagged files commonly are installers or other files that belong to potentially unwanted programs. It is not a secret that Torrent clients have been assigned to that category by many security vendors, so if your antivirus has flagged it, it is up to you whether you want to keep it or not. PUPs, in general, are not as severe when it comes to cybersecurity risks like malware, but they commonly cause unwanted activities (mostly ads) or have questionable privacy policies.

Alternatively, some detections can actually mean something more sinister – Trojans can also hide behind them. These malicious programs might be programmed to steal personal data, harvest your passwords, install other programs or malware, etc. Hence, you should always research it further, as the type of the threat greatly affects your further actions. In most cases, allowing the security app to delete the detected file or folder is the right choice.

People often encounter this heuristic AV detection result after installing programs, plugins, and video games. It can be detected by security programs under different names:

  • PUA:Win32/Presenoker
  • GrayWare/Win32/Presnoker
  • HEUR:Trojan.MSIL.Hesv.gen
  • W32/Presenoker.G!tr
  • Adware.Presenoker.
Name Presenoker virus
Possible types Adware/ PUP/ Trojan
Distribution Insecure software installations, pirating sites, torrent services and files injected with malware attached to safe-looking emails
Danger The malware runs in the background and can be set to perform various malicious activities, including info-stealing and malware dropping purposes. This is the universal detection name that can be easily associated with a handful of different threats
Elimination Virus removal should involve anti-malware tools no matter the particular type of the threat installed on the machine, so anything and everything can get detected and the infection terminated once and for all
Repair Since there are many functions that this threat can manage, you need a proper system repair program that could tackle the virus damage and make sure that performance is recovered and all the files like registry entries are not affected. Try FortectIntego for that

If Presenoker virus turns out to be a browser-based threat it creates issues with your Google Chrome, Mozilla Firefox, Internet Explorer and other web browsers because it focuses on controlling online traffic and redirecting every browser session through sponsored and affiliated sites with potentially harmful commercial material.

Adware or PUP can change preferences of your homepage, default new tab settings, so you visit undesired pages and may get exposed to sites that inject the system directly after clicks, and continuous redirects. It becomes irritating and annoying when you cannot access commonly visited pages.

However, the more dangerous things revolve around the trojan version of the virus:

  • Data theft. Keystroke technology can be used to obtain sensitive information like passwords, banking credentials, logins. This data is valuable for actors and can help hackers to steal money straight from your account or more sensitive files and stored details from the computer itself.
  • Spying. Trojans can run processes in the background including recording sounds and webcam activity. Also, the trojan can be set to record keystrokes on certain or all websites you visit.[2]
  • Usage of resources. Malware can execute commands and use memory, CPU and other resources to run cryptomining processes and put the infected machine to work for other jobs without you even knowing that. These additional processes can be indicated by the high usage of resources or tasks running in the background.
  • Background activities. Trojans can also be set to further infect the machine by stealthily infecting the computer and dropping malware that is more damaging to the system, like ransomware. Remote attackers can use these infiltrations as tools to get on the machine and introduce their direct commands.

Trojans can be extra sneaky and perform actions behind your back without showing any symptoms at all. Experts[3] always note that these more severe infections affect the performance and can damage system files and functions without you realizing what is happening. For that reason, you should employ a sophisticated repair tool that can fix damaged Windows files automatically (otherwise, you might have to reinstall the OS).

So make sure to focus on proper Presenoker virus removal and then run a thorough check using FortectIntego or a similar system optimizer, cleaner tool that could indicate, find and possibly fix affected system files like Windows registry entries. It is not easy to spot the infection itself, so an automatic method with anti-malware tools works the best for the initial malware termination. Presenoker TrojanPresenoker is the generic name of the anti-malware tool detection engine that can indicate an adware-type threat or even an info-stealing trojan.

Potential detections of malicious files or applications associated with the virus can differ, but you should take every AV alert into consideration and always check the system using proper anti-malware tools when you have any suspicions about the security of your system.

Make sure to focus on the infection itself when you want to remove Presenoker virus, not those names or particular detections and heuristic results. You need to worry about the infection itself and possible danger to your files and the affected device, so terminating the malware is more important than finding what type or name this virus is.

If you have a trustworthy anti-malware tool on the system already and it managed to find the virus or a potentially unwanted program on the machine, make sure to double-check and rely on the AV tool that you already use. However, you can get another anti-malware program to make sure that the job gets properly done and get rid of the possible intruders with another security software. We have a few additional suggestions and general tips below.

The danger of software providers and advertisers lies in installations

It is common for AV tools to detect torrent files because of heuristic signatures that look dangerous, or when the torrent installation is bundled with PUP. So when you use such services and sites for installations and don't pay enough attention potentially unwanted programs, undesired applications, and even malware like this trojan.

These services are peer-to-peer, so it means that connections are related to many different IP addresses and can be associated with malicious servers, so anti-malware engines indicate these files as dangerous or even malicious, hence the detection. Pirating services and torrents can also install real viruses like trojans and worms alongside the software you get.

You should either choose official and reliable sources, trustworthy providers, and choose Advanced or Custom installation options or stay away from freeware and online downloads in general. Keep your anti-malware tools up-to-date, so your system can be kept clean.

Use adequate security software to deal with the infection

When you encounter a virus alert for this threat, you should stay contained and not panic, as there is a chance that the detection is a false positive. However, you cannot ignore pop-ups and notifications about potential infections on the machine, so double-checking with proper anti-malware tools can be the best option to determine what to do next.

Then you can choose the method of Presenoker virus removal and follow with a full system scan and PUP or a trojan termination. Choose SpyHunter 5Combo Cleaner or Malwarebytes for the security check and potential threat elimination, so your device can get cleaned fully no mater what intruder got on the computer.

However, when you are ready to remove the virus that falls into the more stealthily and dangerous category of trojans or malware, you may need additional help that System Restore feature or Safe Mode rebooting can provide. By choosing one of these functions, you can completely terminate the malware and get back to a safe machine.

Additionally, tools like FortectIntego can help to find and possibly fix virus damage and repair system files or programs that get altered or disabled by the infection.

How to prevent from getting malware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
