MassLogger is a highly dangerous malicious piece of software that can be categorized as a Trojan horse virus. MassLogger may have snuck into your system completely unnoticed and remained there without exhibiting any symptoms.


The MassLogger Malware

This is actually a characteristic trait of all Trojan horse viruses in general. They are notoriously stealthy and can even disguise themselves as actual system files and even pretend to be system processes in your Task Manager. On top of that, there’s nothing that would give them away in terms of actual infection symptoms, which makes their detection quite difficult. On occasion, however, a Trojan horse infection may cause system crashes and sluggishness, depending on exactly what it’s up to on your computer. But these very same effects could very well be signs of other issues.

This brings us to the other most prominent characteristic Trojan horse trait: versatility. Software like MassLogger can be programmed to execute a very large variety of different malicious tasks, depending on the intentions of the hackers behind it. And because MassLogger is so new, we don’t yet have sufficient data to determine exactly what this piece of malware is designed to do. One thing is for sure, though, and that is that MassLogger needs to be removed from your system as soon as possible. Whatever it’s up to, you can be certain that it isn’t good and there’s no point in allowing it to remain on your PC any longer. Therefore, you can make use of our free removal guide just below this post, which will show you how to locate and delete the virus. Just be sure to stick the instructions very closely so as to avoid accidentally deleting the wrong element.

The MassLogger Malware

The MassLogger malware can be programmed to do all sorts of things. For example, one of the more common usages of Trojan horse viruses is theft of sensitive information. The MassLogger malware can provide the hackers with access to your login details on various websites, passwords, financial data, etc.

Similarly, it may allow the hackers to track your location, your keystrokes (anything you type with the help of your keyboard), and it may even give them access to your screen, webcam and microphone.

Another possibility is MassLogger may be after your computer’s resources for the purpose of mining cryptocurrencies, for example. Alternatively, it may have turned your system into a bot and set it to distribute spam or infect other computers within its network.

Now, as far as the distribution of MassLogger itself goes, there are plenty of options here, too. But the most common by far still happen to be the same old spam messages that have been used to distribute malware since the beginning of time. Malicious online ads have also become a fairly popular Trojan horse transmitter in recent years, so be sure to watch out for those as well. But as far as emails and social media messages go, always be on the lookout for suspicious elements like attachments, unfamiliar senders and other things that may point to danger.

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—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
