.locked or .locked, the items hit by the notorious RAA ransomware require a complex treatment. Otherwise, they represent a gibberish sequence that any software cannot process to a meaningful output.
Once the virus has encoded the files, it modifies their extensions adding .locked or .blocked string. To notify its victims, the ransomware sets the following message as a wallpaper for the desktop. It also drops a copy of the same into every folder.
RAA ransomware warning message

The message above addresses the victims in Russian. However, the virus propagates worldwide. Perhaps, soon we will spot the ransom note in English and other languages.
The RAA propagates using a range of scenarios. An exploit kit often executes the installation of ultimate malware. The infecting routine provides for visiting cracked websites exploiting vulnerabilities in such software as Flash Player, PDF Reader, and Java. That is the worst option possible. Preventing the invasion is virtually impossible due to the highly obfuscated technology applied. Yet another workflow leverages email attachments that operate as a minefield. The files attached explode at opening as the opening automatically executes the extortionist’s directives. The scammers may disguise the letters as a notification issued by your bank, Revenue Office, accountant etc.
We need to admit that decrypting the files appended with .locked or .blocked extension is virtually impossible. Fortunately, a range of options capable of restoring the affected data is available as laid down below.
Automated cleanup to remove .locekd and .blocked file extension trojan
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed RAA locker, unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of RAA ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wail until the cleaner checks the PC for RAA ransomware files malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
RAA locker encryption (.locked and .blocked) is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of the .RAA (.locked and .blocked) ransomware
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by RAA ransomware, make sure the removal of RAA virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
