Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is Blackout ransomware? And how does it work?
Blackout ransomware is a file-encoder virus that claims to tests “the protection of OS Windows against ransomware”. It deceives its victims into thinking that they have to test their Windows operating system against ransomware infections. However, once you “test” your OS, the malware will tell you that your files got “accidentally” encrypted. It was developed using the HiddenTear open source platform. After the so-called “test”, it starts to scan your computer for files. According to our researchers, it mostly targets files under these locations: %PUBLIC%, %USERPROFILE% and %ALLUSERSPROFILE%. What’s more is that aside from encrypting the files using AES algorithm, this virus also has the ability to lock .exe files. If the happens, you won’t be able to start your programs in any way. After the encryption, it drops a file named README_1183339_23654.txt containing the message below.
“Blackout ransomware is a free open source software.
The program is designed to test the protection of OS Windows against ransomware.
The developer of this software is not responsible for any damage caused by the program.
The program is experimental, and the entire responsibility for use lies with the user.
HOW TO USE:

How does Blackout ransomware spread?
Since this is still a Windows-based malware infection, it’s pretty clear that Blackout ransomware’s distribution method is quite limited so it is most likely distributed through torrent or gaming sites. The malicious file created by this ransomware might be disguised in an application or files that can be found in such sites.
In addition, you can also get infected by opening malicious spam emails with corrupted attachments as well as exploit kits. In such cases, you have to keep your system protected by making sure that your antivirus program and operating system up-to-date.
