Hi guys I am in a hurry so i'll be quick: my father bleeped up his computer, and now It has this teslacrypt malware.
I did these things in order:
-Looked for files in %appdata%: i found a txt and html ransom note, an executable and a backup.dm file. No key.dat.
-Ran anti malware softwares (adwcleaner, combofix, rkill, tdss) but no success
-I ran rannohdecryptor and rectordecryptor from kaspersky and i could do anything
-The new MALWAREBYTES tool doesn't start on the infected pc, it says an error
-System restore points don't work.
-I think the computer is still infected since I cant install nod32 (error 1603), but i'll keep trying.
Here is the pastebin of the txt ransom note: http://pastebin.com/i5gBa10n
Here is a photo of the html ransom: http://i.imgur.com/aMvny9U.jpg
Here is photo of a key i found in HKCU\Software\EA1F202260A71763: http://i.imgur.com/0gpyIsy.jpg
I have a lot of office documents I need to restore.
Thank you a lot.

TeslaCrypt ransomware includes several known versions with various extensions for encrypted files such as .ecc, .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc, .vvv as described here. Any files that are encrypted with TeslaCrypt 3.0 will have the .xxx, .ttt or .micro extension appended to the end of the filename as described in this news article and leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, and Howto_Restore_FILES.TXT.

There currently is no way of decrypting TeslaCrypt 3.0 .xxx, .ttt, or .micro variants since they use a different protection/key exchange algorithm and the key for them cannot be recovered. The .xxx, .ttt and .micro variants are not supported by the current released version of TeslaViewer. If infected with any of these, backup all your encrypted files, send BloodDolly a private message with a link to few encrypted files after uploading them to SendSpace (see instructions in Post #1) and wait for solution.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance.You can also post comments in the related BC News article:Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in one of those topic discussions, particularly the last if dealing with one of the newer variants. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.
