I have a HP Pavilion g6, got in 2012.

Two days back this fake window started showing on my laptop. It says - user control - at top and is titled - Command Line Interface for Microsoft - there is a small R in circle icon after Microsoft  - asking 'Do you want this to make changes to your computer? the name of the company was 'Microsoft Windows'. I was skeptical so I pressed 'No', the window pops up again in a second. After a few times, I suspected something wrong, wanted to shutdown the laptop. The window keeps popping up within that two seconds ! I kept at it and clicked shutdown 2 -3 times. Finally it shut down. Next morning when I turned it on, the fake window appeared again and again.


I shut it down and took the computer to an electronics / computer (sales/support) store. The man looked at it and said - "it looks genuine, some controls were probably turned off , so i will say 'yes' ". Then he clicked 'yes' and the window disappeared. It all looked normal again.

I turned on the computer after coming home - the window popped again - as I was told at the store that it was genuine, I clicked 'yes' . thought everything was ok now. Then I opened a pdf file. It did not open - The icon changed too - now the name of the file was MICRO.pdf or pdf.Micro ! I disconnected the internet & transferred most important files to a hard drive. During this exercise, I noticed. pdf icons & some mp.4 also changing. surprisingly mp.3 s stayed as they were. I have lot of pdf and .mp4 stuff on my computer for my volunteer translation work & also personal use. 


I transferred some folders - almost all .pdf stuff has changed to Micro.


During the transfer, after  about 15 minutes, a notepad window came -up. 'which language is this?' - i thought I accidentally opened some notepad document - so closed it. After a minute, it popped again. Closed it. Popped up again - then I read it quickly - It said something like - "&8%4#6@ what is this language? Ha ha. now you know. You can not do anything.only if you go to this site - only if you pay money, you will know how to get rid of this. only we can do this "" etc., etc., 


Now I understood. I stopped the transfers & shut off the computer and writing to you. 


As of now, I understand my hard drive also has some Micro   files. 


Please help!

Sounds like you are dealing with the newest variant of TeslaCrypt ransomware...TeslaCrypt 3.0 will have the .xxx, .ttt or .micro extension appended to the end of the filename as described in this news article. TeslaCrypt 3.0 will leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, and Howto_Restore_FILES.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 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.
