There is also a very good reason for their extreme popularity, and it is the combination of two important factors – their ability to remain hidden in the system for long periods of time, and the wide range of criminal tasks they can perform. In the following article, we will illustrate what we mean by that, therefore we advise you to spend a few minutes reading the information below before jumping to the removal guide and its instructions. We will do our best to shed as much light as possible on this malware category, and also provide you with some useful information on how to remove such infections from your system effectively.

What could Pterodo be capable of?

It has the ability to perform various different tasks one after the other without showing visible symptoms. Here’s just a glimpse of what Trojans like this one are typically used for:

  • Trojans like Pterodo, Bloom.exeGreat Discover can often be programmed to steal information from a given machine, whether it’s professional or personal. This may also apply to stealing financial details, such as the credentials for your online banking accounts, and your credit or debit card numbers.
  • These malicious pieces of software can be specifically designed to monitor the victim’s activities, and report them back to their creators. They are very good at keeping track of every move you make, and sometimes not just online. An infection like Pterodo, for instance, could be programmed to switch on your webcam and hack into your microphone to spy on your physical activities, as well as on your conversations. This is a serious violation of privacy and can have serious consequences if the hackers behind the Trojan turn out to be burglars, blackmailers, and so on.
  • In some instances, a Trojan can infiltrate your computer with the purpose of destroying some important data stored on it. As a result, your hard disk can be formatted and could lose all the valuable files that you keep on it. To make matters worse, such malware could crash your entire device, and make it totally unusable.
  • In addition to all of the above, an infection like Pterodo could introduce additional malware to your system without your knowledge. The notorious Ransomware cryptoviruses, for instance, are known for using Trojans as backdoors in order to infect their victims. However other viruses and malicious scripts could also sneak in with the help of the active Trojan, since such software may block the security program in the infected computer, and/or create system vulnerabilities that can easily be exploited.

So, with all this terrifying information at hand, it’s clear why your next step should be to remove Pterodo from your system. You can use the instructions below for help, or simply run a system scan with a reliable security program like the one in the guide.

    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:

    hosts_opt (1)


    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

    If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
