This page aims to help you remove Winnti Malware. Our removal instructions work for every version of Windows.

The original Trojan horse has appeared long before computers and Internet existed. This was in the ancient Greek world of mythic battles and brave soldiers. The Trojan horse was originally a huge wooden statue given to the city of Troy as a gift. What the citizens did not know was that the giant horse was full of Greek soldiers ready to invade and conquer the city. Today, the phrase Trojan Horse means something very different from a wooden statue. However, its concept remains similar and equally destructive.

In modern times, the Trojan horse (Trojan) is a type of malicious software that infects your computer secretly and then causes chaos in your system by causing different issues and conducting various malicious tasks. Each Trojan-based infection may have a different task but, on this page, we will stop our attention at one of the latest representatives of this category, a threat called Winnti . This malware program is a sophisticated Trojan-based software which can be very difficult to detect and remove and can perform many malicious activities like some of the following:

  • Acquire passwords and personal data and access your online accounts.
  • Steal bank data and credit/debit card information and online banking details.
  • Destroy and/or delete important files and software in the infected system.
  • Collect personal information and steal/abuse your virtual identity.
  • Insert other viruses and malware such as Ransomware, Spyware and Rootkits in the user’s computer.
  • Exploit System resource for additional criminal background activities.

The list of possible malicious actions initiated by this malware may go on and on and that’s why you can expect much more than the above-mentioned in case your computer has been infected.

How to detect and avoid Trojans like Winnti ?

The Trojans are incredibly good at hiding themselves inside seemingly-harmless files, ads, attachments, pop-ups, software installers, email messages and more. The whole point of their existence is to trick the users into installing them and then operate in stealth and silence until they achieve their criminal goals. If you are a victim of such a virus, you may not even realize it until it is too late. That’s why it is a good idea to watch out for some of these signs, which may be a warning that you may need to remove something malicious from the background of the system.

  • Unusual system behavior – Any unusual increase in the CPU and RAM usage could be a sign of a problem or a possible Trojan horse infection, especially if you aren’t conducting any resource-demanding activities in the system.
  • System failures – If your system suddenly slows down considerably or starts crashing regularly, this could be a sign of trouble. Use a high-quality security program to see if you can find the problem.
  • Unidentified programs – If you notice an application or program that you have not intentionally downloaded, this may be a cause for concern. Check its name on Google to make sure it is not an important part of the operating system. If it is not, then may be a good idea to remove the unwelcome software and then run a full system scan.

Unfortunately, there is no guarantee that you will notice any specific symptoms if Winnti is in your machine. The Trojan horses are a complex form of malware so you may need more than your vigilance and watchfulness to spot them. In the removal guide below, we explain what you need to do to deal with such threats but using software such as antivirus programs and firewalls will provide you with an extra layer of protection so do not forget about that.

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:

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
