RSA-1024 Virus (Encryption and Ransomware) Removal


How irritating is this virus?

This page aims to help you remove viruses using the RSA-1024 encryption algorithm for free. Our instructions also cover how any RSA-1024 algorithm encrypted file can be recovered.

No one likes having their computer attacked by viruses and their personal data messed with. That is why there are so many different anti-virus programs that aim to provide your system with protection against such malicious software. For the most part, such security programs work and give your machine the protection it needs. However, there is a type of PC viruses that seems to remain under the radar of most anti-virus tools due to its devious approach and rapid evolution. We are talking about Ransomware – a particularly nasty kind of harmful programs that are currently among the worst software threats that you can encounter online.

The RSA-1024 algorithm

The RSA-1024 algorithm uses two sequence of large prime numbers.

RSA-1024 algorithm

The acronym RSA-1024 is derived from the Rivest-Shamir-Adleman – a cryptosystem, which uses two keys composed of prime numbers in order to encrypt large volumes of data. Cryptography, and especially Public Key Cryptography is a large field of study that sees many applications, especially in the area of computing and data transfer security. Unfortunately, recent advancement into the field of Public Key Cryptography has opened the door for a particularly nasty type of virus called ransomware.

A Ransomware virus using the RSA-1024 encryption algorithm goes straight after your files and uses the RSA-1024 algorithm to encrypt your files. Please note, that since the RSA-1024 algorithm uses two keys in order to function most ransomware programs are accompanied by a Trojan-virus. The job of the Trojan is usually to establish a remote connection with a host file, which distributes the public keys used. One of the keys is left on the infected computer, to be later used by the owner if he decides to pay for the ransom.

Why is Ransomware so difficult to detect?

As we already mentioned above, one of the main reasons why this particular kind of harmful software is so dangerous is because it very often remains undetected until way too late. This all has to do with the unique and devious agenda of typical Ransomware compared to other types of viruses. RSA-1024 and most other Ransomware programs use an encryption to lock your files. While the code makes you unable to access your files, it is not inherently malicious. Many legit programs actually use encryption for their files. The difference is that you can access those, whereas if Ransomware encrypts your documents, you won’t be able to open any of them because you won’t have the necessary key. This is also where the ransom part comes into play. After the virus has locked your data, it displays a message on your screen that demands a ransom payment in return for the decryption key. Instructions on how to send the money to the blackmailer are usually provided to ensure that everything goes according to the demands of the hacker.


In the majority of cases Ransomware hackers require their ransom in bitcoins. This is a cryptocurrency that is basically untraceable. This leaves the cyber-criminal in full anonymity during and after the money transfer. This makes fighting hackers that use Ransomware viruses that much more difficult and is also one of the main reasons why programs using the RSA-1024 algorithm are becoming so popular at such a rapid pace. Furthermore, the more widely spread Ransomware becomes, the more effort is put into improving the newer virus versions making them even more difficult to handle.

Manual detection

Maybe your anti-virus cannot detect the encryption process. However, it is possible that you can do that manually, by being vigilant and noticing any strange PC behavior that may occur. This is because RSA-1024 needs some time to encrypt your data and often requires considerable amounts of system resources. In fact, once the virus gets inside your PC, it first needs to make a copy of all targeted files – those copies are actually the ones locked by the encryption. However, after the RSA-1024 algorithm has done that, it deletes the originals and you’re left with the encrypted copies. Still, the time and resources this process requires might give you the opportunity to intercept it. Thus, if you notice any of the mentioned symptoms, make sure to shut down your machine and have it taken to an IT specialist. Also, remember to not connect any portable devices to your PC during this time because if there is a virus, they might get infected as well.

What to do if your data has already been locked and how to keep your PC safe in the future?

One very important thing to know if your files have already been encrypted is that paying the ransom is a very bad idea. Even if you follow all the instructions and pay the money you still might not get the key for the code. Therefore, our advice for you is to seek another way to resolve the problem. One possible course of action is to try our removal guide located below this article. It will help you remove the virus, however keep in mind that due to the devious nature of Ransomware viruses, we cannot guarantee that it will be able to restore all your files. Nevertheless, it will cost you nothing and might save you a lot of time and money in return. Now, here are some important tips that will help you keep your system safe in future.

  • Get a high-quality anti-virus program – Ransomware often infects people’s PC’s through other viruses that serve as a backdoor.
  • Avoid opening any shady e-mails and suspicious hyperlinks.
  • Stay away from any obscure websites and do not download anything from sources that you cannot fully trust.
  • Make a back-up of all important files that you have and update it frequently so that no valuable data is left without a back-up copy.


NameRSA-1024 (this is the encryption model – the actual virus can be one of many things)
Symptoms Heavily reduced PC productivity and high system resource consumption throughout the duration of the encryption process.
Distribution MethodNormally, Ransomware programs get to people’s PC’s via spam e-mails and with the aid of backdoor viruses.

    You must delete those IP’s since they are coming from the virus. Then save the changes to the hosts file. Note that you will need to have accessed the hosts file with Administrator privileges.
