Hi to everyone i'm new on this forum and on this new kind of malware for me! My girlfriend has got an infection of ransomware on her laptop. This is an old laptop and has got a lot of problem but she want to fix it anywhere. I do a scan with karspersky virus removal and it found a lot of objects that i have already remove but the encripted files are still encripted obviously. There is a solution for this problem? I don't want to give the money at this hacker. I launch Combofix now and i'm waiting the creation of the file's log for post it here. Anyone can help me? Thank you for your time.

Welcome to Bleeping Computer.

Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc, .vvv, .encrypted, .crinf, .XRNT, .XTBL, .crypt, .pzdc, .good, .LOL!, .OMG!, .RDM, .EnCiPhErEd, {CRYPTENDBLACKDC}, .vault, .HA3, .toxcrypt, .CTBL, .CTB2, or 6-7 length extension consisting of random characters?

Did you find any ransom note? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file.

These are some examples:
HELP_DECRYPT.TXT, HELP_YOUR_FILES.TXT, HELP_TO_DECRYPT_YOUR_FILES.txt, YOURFILES.HTML
HELP_RESTORE_FILES.txt, HELP_TO_SAVE_FILES.txt, RECOVERY_KEY.txt, DecryptAllFiles.txt
DECRYPT_INSTRUCTIONS.TXT, DECRYPT_INSTRUCTION.TXT, HOW_TO_DECRYPT_FILES.txt
How_To_Recover_Files.txt, ReadDecryptFilesHere.txt, Help_Decrypt.txt, About_Files.txt
RECOVERY_FILES.txt, DecryptAllFiles_<user name>.txt, encryptor_raas_readme_liesmich.txt
Howto_RESTORE_FILES_*****.txt, DecryptAllFiles_*******.txt (where * are 6-7 random characters)
RECOVERY_FILE_*****.txt, restore_files_*****.txt (where * are random characters)
howto_recover_file_*****.txt, _how_recover_*****.txt (where * are random characters)
how_recover+***.txt, recover_file_*****.txt, (where * are random characters)
Once you have identified which particular ransomware you are dealing with, I can direct you to the appropriate discussion topic for further assistance.

I moved your topic here because you did not follow the Malware Removal and Log Section Preparation Guide.

ComboFix logs are not permitted in this forum so do not post it here. Many crypto ransomware variants are typically programmed to automatically remove the malicious files responsible for the infection after the encrypting is done since they are no longer needed. However, if another piece of malware was responsible for installing it, then that could still be present if your antivirus did not detect and remove it.

If you need individual assistance ONLY with malware infection, follow the instructions in the Malware Removal and Log Section Preparation Guide. When you have done that, start a new topic and post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

If you choose to post a log, please reply back in this thread with a link to the new topic so we can closed this one.
