Windows 10: I have infected with Ransomware where it changes file extensions to .lisp

Hello,


My laptop has been recently affected with .lisp Ransomware corrupting all my computer files. Every file is been corrupted with .lisp extension and is now unable to open. Attached herewith is a text file with the virus demanding money to decrypt the corrupted data. The anti-virus in the laptop has been recently expired so at present there is no active anti-virus present in my system.

Is there any method to get rid of the ransomware and recover my files.

If soo, please do help me in recovering my data.


[Original Title: .lisp Ransomware]

Oh.

I see that a Community Moderator converted your thread from a Discussion to a Question.

Do you have a question?

It is not quite clear (to me at least) why you've created this thread....

In case that you do indeed have a problem with ransomware:

It would be helpful if you would describe your problem more precisely, see:

Ransomware infection?

My computer has been infected by a something that has changed the file extensions of my Word documents to '.Merry'. Windows Defender appears to have removed the insidious thing from my computer but all that I am reading suggests that may not be the case.
Additionally, it appears that there is no way for me to decrypt and restore my files so that I may access them. Can anyone help me separate fact from advertisement, please? Is there any way to recover my files? Is there a sure way to know that the ransomware
has been removed from my computer? For clarification, I am using Windows 10.

Ransomware infection?

Any files that are encrypted with MRCR1 Ransomware will have the the
.MRCR1.PEGS1, .RARE1,
.RMCM1 or .MERRY extension appended to the end of the encrypted data filename and leave files (ransome notes) named YOUR_FILES_ARE_DEAD.HTA as explained

here. The ransom note instructs victims to contact the cyber-criminals at "L: *** Email address is removed for privacy ***" or "TELEGRAM @comodosecurity" to get payment instructions.

You can submit samples of encrypted files and ransom notes to ID Ransomware for
assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further
assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.

Fabian Wosar released a decryptor tool for victims of this type of infection.

Most crypto malware ransomware is typically programmed to automatically remove itself...the malicious files responsible for the infection...after the encrypting is done since they are no longer needed. That explains why many security scanners
do not find anything after the fact. The encrypted files do not contain malicious code so they are safe. Unfortunately, most victims do not realize they have been infected until the ransomware displays the ransom note and the files have already
been encrypted. In some cases there may be no ransom note and discovery only occurs at a later time when attempting to open an encrypted file. As such, they don't know how long the malware was on the system before being alerted or if
other malware was downloaded and installed along with the ransomware. If other malware was involved it could still be present so be sure to perform full scans with your anti-virus.
Disinfection will not help with decryption of any files affected by the ransomware.

If your antivirus did not detect and remove anything, additional scans should be performed with other security programs like

Malwarebytes 3.0,
HitmanPro and
Emsisoft Anti-Malware. You can also supplement your anti-virus or get a second opinion by performing an

Online Virus Scan...ESET is one of the more effective online scanners.
