If you are reading this article it is likely that RSA CryptoSystem Virus has already revealed its presence to you and is demanding ransom. Your computer has been infected by a very dangerous type of virus known as ransomware. It has the ability to encrypt your files and make them unusable – you can easily notice the encrypted files due to the unfamiliar file extension that has been added to them. What makes ransomware so dangerous is the fact that even if you remove it files that have been already encrypted remain so. We’ll do our best to help you recover your files and also teach you a few basic tips that will go a long way towards keeping your PC safe.

RSA CryptoSystem Virus – an overview

This ransomware is relatively knew, but it adheres to an old and well tested doctrine established by three very successful ransomware viruses that came before it – TeslaCrypt, Cryptowall and CryptLocker. Basically, when the ransomware is installed on a computer it will remain hidden and begin encrypting your files. It actually possible to easily detect the virus at this stage and prevent it from inflicting lasting damage if you pay attention to the signs – your computer will suddenly start working poorly. The encryption process consumes a lot of CPU power and memory and is the reason behind the reduced performance. You can easily spot the ransomware process if you open your task managed and sort processes based the amount of CPU and Memory they currently use. Afraid any such process and don’t be alarmed if it is named as something that sounds important and dangerous to touch – you can’t really damage your computer in this way and ransomware is known to mask itself as a fake system process.

How to prevent your PC from becoming infected with ransomware

Keeping your PC ransomware-free is actually much easier then dealing with the virus itself. If you follow these simple rules you’ll never have to deal with this type of threat (and also many others) again.

  • Don’t download and install executable files from unsafe sources. The internet is a huge place and search engines make it very easy to quickly obtain different kind of programs, but many of the places these programs are hosted are not safe. Any unofficial mirror, download platform or torrent site can potentially land you with an infected file. Try to avoid downloading files from such sources or at least scan them with security software before using them
  • Email attachments are prime way to get infected. Not all harmful emails contain broken English – in fact the most dangerous emails are well written and sound quite normal. Dangerous emails are those that offer you a link to click on in order to avoid a problem or those that want you to download a certain file. Business-related emails tend to be less suspicious, as it is very easy to create some generic business text about an offer that is contained within the attached file.
  • Scan your computer regularly for viruses – in fact it is a good idea to have your anti-virus scan your computer routinely every day in hours which you don’t use it – nearly all security programs offer this option. Trojan horses are another dangerous type of viruses that can install Ransomware or do other really nasty things to your computer


Files already encrypted by RSA CryptoSystem Virus have been completely re-written, changing their name or deleting the file extension will not repair them. There are also a number of programs circulating the web that claim to be able to decrypt ransomware encrypted files – be wary of them. All decrypting solutions that have been discovered are available for free. Everything else is a scam. Always ask for definite proof from the authors of such programs before paying any money for them.
