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. 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 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 Anti-Malware
and Emsisoft Anti-Malware
. You can also supplement your anti-virus or get a second opinion by performing an Online Virus Scan
is one of the more effective online scanners.Trend Micro
released a Ransomware File Decryptor
for victims of earlier Cerber v1 infections but it has limitations. Expand the CERBER Decryption Limitations link near the bottom of the page...must be used on the infected machine, may take several hours to complete decryption, some files may be only partially decrypted
Trend Micro's decryption tool does not work on Cerber v2/v3
encrypted files or the newer v4x/v5x
which uses 10 random characters with a random 4 character (i.e. .b71c
) extension. Unfortunately that means, there is still no way to decrypt files by these variants without paying the ransom.
There is an ongoing discussion in this topic where you can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
