Hello to all, as someone already knows, I have one computer infected with Tesla 3.0.

Now, after malwarebytes scan, kaspersky virus removal tool scan, kaspersky antivirus 2016 (just installed) scan and a Registry Mechanic scan and fix, after a manual double check in directories and registry editor, seems that everything is clean (the .micro files still exist, ok, but this is not the point, continue to read)

 

Now, that kind of ransomware create thousand (I just removed at least +300000 files) named "help recover instructions+vhg" or "help recover instructions+[other letters]"

 

To delete them faster, I have used the search ("help recover instructions" query) function, it find all of these with that name, then CTRL+A and DEL

 

What I'm not understanding is after deletion I'm still able to find them always everywhere!!!!

 

Any comment will be greatly aprreciated!!!

 

 

Tks in advance

Ok, fixed.

Using the method described the files were not deleted because they were so many that explorer crash, they were not propagating themself

 

I used instead CCleaner Free, in the tools section you can search for duplicates, it takes a long time anyway but at least it doesn't crash and it did a very good job (repeat the scan more than one time per drive, then use my windows search method to delete the last 15...)

 

I think to have deleted not less than 500000 files of this stuff.... WOW!!!

 

I hope to have been useful for someone

 

Cheers!

TeslaCrypt ransomware includes several known versions with various extensions for encrypted files. 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, Howto_Restore_FILES.TXT and help_recover_instructions+[random].txt.

A repository of all current knowledge regarding TeslaCrypt, Alpha Crypt and newer variants is provided by Grinler (aka Lawrence Abrams), in this topic: TeslaCrypt and Alpha Crypt Ransomware Information Guide and FAQ.

There currently is no way of decrypting TeslaCrypt 3.0 .xxx, .ttt, or .micro variants since they use a different protection/key exchange algorithm, a different method of key storage and the key for them cannot be recovered. The .xxx, .ttt and .micro variants do not have a SharedSecret*PrivateKey so they are not supported by the current version of TeslaViewer. If infected with any of these extensions, 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 more questions, comments or requests for assistance in that topic discussion. Thanks for sharing your experience with removing all those files using CCleaner.

To avoid unnecessary confusion...this topic is closed.

Thanks
