AcroRd32_sbx Trojan


We have recently received a number of complaints about a Trojan Horse variant, called AcroRd32_sbx. Trojan Horse viruses like AcroRd32_sbx are some of the most malicious pieces of malware that you might ever encounter. They are extremely stealthy and can harm their victims in a variety of ways.


Considering that you’ve landed on this page, we guess that this malicious program has compromised you, and you are seeking a way to remove it. If so, here you will discover a removal manual with step-by-step instructions on how to delete AcroRd32_sbx from your scheme. Alternatively, you can also use a professional removal tool that we recommend, which is also available below, if you don’t trust your computing skills to handle the Trojan infection.

The nature of the Trojan Horse viruses

One of the main problems with Trojan Horse infections is that when you find them on your computer, you can’t be sure precisely what they are up to. Those threats are very versatile, but we still want you to give you a clearer image of what you may be up against. To start off, you should know that Trojans such as AcroRd32_sbx, Trojan.WIN32.PDF.Alien.gen, Great Discover are most frequently used to steal data. There are many ways in which they can do this, including keylogging, for instance. Using this technique, the virus can record everything you type, and thereby possibly discover your logins, passwords, or other personal information.

A Trojan can also be used to delete files, crash, or even totally destroy your system. Such an action can be extremely harmful if you keep important data on the machine, especially if it is related to your work, or to your personal life.

Their ability to spy on you is another relatively common and no less hazardous use of many Trojans. These threats can literally operate as a window for the hackers who are in control of it to watch directly at you, listen to your conversations, and track every move you make. This is a really disturbing possibility, and one more good reason to remove AcroRd32_sbx as soon as possible.

However, this is not everything. Most Trojans can also be used to infiltrate your system, to and use your computer resources for various purposes. For instance, they can spread spam through your infected machine, or even invite other malware, such as Ransomware or Rootkits, inside your system without your knowledge.

Sadly, this is just a brief and incomplete list of all the capabilities of infections such as AcroRd32_sbx. The fact that they have hardly any symptoms is another thing that makes Trojans like this one so hazardous. This means it’s very hard to detect the actual malware on your PC, and, in most cases, you may need a professional removal tool to correctly locate, and remove it.

But the best way to protect your system from Trojans is to never let them get into it in the first place. So, once you have removed the current one, try to apply some basic security measures to your daily browsing activities. For instance, avoid places that are suspicious, and try not to download materials from any such website unless you are sure you can trust it. The various forms of spam messages you can receive via email, social media, and other messaging platforms are still a very common source of different malware infections, including Trojans, so don’t interact with them either.

    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:

    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
