Win64:pup-gen detection  nameWin64:pup-gen is an AV detection that may indicate a Windows activation crack infringements

Win64:pup-gen is a detection name that is typically displayed by security programs, such as AVG, Sophos, Avast, and others. Although this detection might be a false positive due to some faulty virus definition, which might have been installed with the latest security updates, the mentioned AV detection is likely to be triggered by a potentially unwanted program (PUP) or malware.

According to cybersecurity experts, the Win64:pup-gen virus alert may be triggered by windowsdefender.exe, SppExtComObjHook.dll, and similar files. Often the alert reports the relation with the svchost.exe process and the C:\Windows\Temp\ location. If your anti-virus program displays suchlike alerts, there's a high risk of having an untrustworthy application running in the background. Thus, it's recommended rebooting the system into Safe Mode and running a full anti-malware scan.

According to Avast[1], the report of the Win64:pup-gen malware in relation to the SppExtComObjHook.dll file is the consequence of downloading software cracks for illegal activation of Windows OS. To check the ongoing malware detections and other system malfunctioning, experts recommend removing the content from the Temp folder and uninstalling cracking tools, such as AutoKMS, Re-Loader, KMSPico, and others.

It's possible that the Win64:pup-gen detection is false because of some AV update problems and inconsistencies. However, experts from AVG warn that this detection usually has a serious ground and should be treated carefully. People who receive an alert that contains the below-given information should take immediate steps to clean the machine from PUP/malware/Trojan infection:

The detection is apparently related to the SppExtComObjHook.dll, which is one of the files that belong to the Windows license cracking tools. Users who are not aware of crack tools and did not download something like that recently are strongly advised to delete the Temp folder and then repeat a scan with the AV engine. To remove this folder, you should:

  • Press Windows key + R to open the run dialog.

Upon the Win64:pup-gen removal, try running a scan with a system optimization tool, such as FortectIntego. You may question why you need a repair tool at all, but there's an important fact to mention – malware, virus, and PUPs tend to leave their footprints under system locations, such as Windows Registry, Temp folders, web browsers, etc. Luckily, a reliable optimization tool can help to fix malware damage quite easily. That's why you need it.

If you are not an expert in malware removal, then you should follow the Win64:pup-gen removal guide that has been submitted by 2-spyware security experts. You should follow each step and perform them in the right sequence.

PUP and malware infiltration strategies

Adware, browser hijackers, and similar PUPs are usually spread bundled with freeware and shareware. They cannot be installed on the system without the user's approval, which is why this type of apps is not considered malicious. The only way to stay away from PUPs is to be cautious during freeware installation processes.

However, dangerous viruses, such as spyware, Trojans, keyloggers, worms, etc. take advantage of stealthy infiltration strategies, for instance:

  • infected spam email attachment[2];
  • illegal/pirated software, such as cracks or keygens;
  • fake software updates;
  • misleading ads on suspicious websites, etc.

In order to maintain the machine malware-free, you should mind precautionary measures all the time. Cybersecurity experts from[3] distinguish the following means of security as the most important:

  • install a professional anti-virus program and keep it up-to-date;
  • install software or its updates from the official developer’s websites;
  • do not use file-sharing services or P2P networks;
  • bypass questionable or, contrary, eye-catchy pop-up ads that promote system tools, browser helper tools, warn about missing updates or offer to subscribe to Push Notifications;
  • ensure that the real-time protection is enabled on your AV settings;
  • avoid visiting potentially dangerous websites, such as gambling, gaming, or pornographic
  • do not open suspicious attachments that are provided in the misleading emails.

Eliminate Win64:pup-gen virus from the system

It may sometimes be difficult to understand if the AV engine alerts are real or false positive. Thus, it's not advisable to ignore any security warnings as your machine may be running a potentially dangerous or malicious infection that may cause serious damage. If you've been reported about Win64:pup-gen virus, we recommend restarting the machine into Safe Mode with Networking, deleting the Temp folder, and then initiate a full system scan with the AV tool.

As we have already pointed out, this particular infection may be related to Windows license cracking tools. Thus, if you have been using such apps, we recommend you to start Win64:pup-gen removal from a full uninstall of all pirated software and their remnants. After that, re-scan the system with an anti-malware program.

Anyway, we do not recommend you to remove Win64:pup-gen virus manually. This detection may be related to several unwanted programs, malware, PUPs, and so on. Thus, the only reliable remedy is a professional AV tool. Our recommended programs are SpyHunter 5Combo Cleaner or Malwarebytes.

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.
