How to remove Gamma virus and restore encrypted files

If you've suffered from an encrypting infection and you know that it’s the Gamma virus – here you will find useful information. We suggest easy and safe instructions for Gamma deletion and possible ways to get back the corrupted data.

What is Gamma virus

Let's find out, what is ransomware? It consists of an absolutely legitimate encryption algorithm that modifies the folders on customer’s workstation, so customer can't use them in any way. The key is also encrypted with another method. In most cases, web-criminals favour RSA and AES methods, that are famous for their complicacy and reliability. The mentioned methods and the software based on them are freely available in the Net, so swindlers just need to add techniques of defense, to block an access to a virus, and make the perfect control and update system. Some encrypting tools may function on their own, and web-criminals know of another "client" not before he writes them and forwards the ransom. The complex ransomwares are function in another manner, and deliver data to hundreds servers, to puzzle the security specialists and maximize the work needed to defeat a ransomware.



Bypassing the virus' kind, the RSA and AES algorithms are very complicated to decipher them directly. It can take centuries to execute all necessary operations on a regular machine or, maybe, twenty or thirty years in case of usage of a mega-powerful gear. The only way to beat a decent virus is to hack into it, or break into its database, to receive encryption keys. Some ransomware examples also have a switch, able to stop ransomware's activity in full or to drive it off the infected computer. If anyone discovers that switch for Gamma, or create a decryptor, we'll provide you with complete information in this item.


There are some possibilities to check, until you can give up and look for a decryptor. As it is said in previous paragraphs, scammers make failures, and certain peculiarities of your Windows can support you to get back your data.


  • A backup is the only fully efficient way to restore your information, but you should uninstall Gamma first. Ensure that the virus is eliminated totally, since if it isn't – all data will be encrypted instantly, with those that were kept on an outer hard drive.
  • If your system account doesn't have administrator capabilities – it's time to compliment yourself. The thing is that your system duplicates all data until they’re eliminated or altered. These copies are called SVC, and the ransomware has the ways to erase them. If you are employing the regular entry – the operating system asks for a confirmation at the exact second Gamma attempts to remove SVC. In case you've seen such window and reversed it – then the SVC are fine, and could be used to restore the data.


In case you checked all these things and you have no way to get back the data – you should eliminate the malware from the computer and expect when a decryption software will be published.

How to remove Gamma

As for the uninstalling – you can't totally avoid an automatic mode. Gamma is very stealthy and you will definitely miss some remains and then suffer from it (for instance, when you line up a flash data storage with your saved data to a not-fully-cleared machine). It knows how to hide very good, and you literally can't remove it completely in manual mode. Here's your removal directions that will suit all your needs. It consists of several by-hand phases and one extra AV tool stage.
