What could a Trojan-based virus such as Ostap do?

The Trojan Horse infections are considered extremely dangerous and there is a good reason for that. These threats have the ability to operate stealthily and infect the computer of the user showing little to no symptoms. That’s why the victims usually do not even know that they have been compromised until some major damage occurs and the system begins to act strangely.

Before any visible symptoms occur, however, a threat like Ostap can secretly download onto your computer additional harmful software programs, such as different versions of Ransomware or Spyware.

Unfortunately, this is not the only thing a Trojan can do. The cybercriminals who create such infections can use them to manipulate your computer in many ways. They may gain remote access to the entire system and all the information that is stored on it, or they may steal sensitive data such as your credit and debit card numbers, your online accounts, or your digital identity. This can later enable the cyber criminals to perform cyber crimes on your behalf or access your bank accounts and drain them without your knowledge.

In many instances, the hackers may use a Trojan like Ostap to spy on you and watch everything that you do on your screen. They can remotely switch on and off all devices connected to your system, such as web cameras, microphones, speakers, etc., or launch specific programs and background processes without your knowledge.

With this being said, there is no doubt that you need to remove Ostap without losing time. If you are not a very tech-savvy person or you fear that you cannot deal with a Trojan Horse like this one on your own, arm yourself with a trusted security tool and use the detailed removal guide from this page to increase your chances of effectively deleting this malware.

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
