Please advise. Thanks

A very nasty ransomware infection has been reported to significantly increase its infections over consumer user PCs encrypting thousands of files per infected computer. The ransomware then leaves this ransom note naming it Recovery.bmp:



First, before decrypting the files you need to do it safely. Use this tutorial in order to remove the virus .tmp files:

Now it is time to decrypt your data. Fortunately for users, Kaspersky has released a decryptor for this nasty ransomware, going by the name of Raknidecryptor. You can download it from by clicking on this link:

Once you have downloaded rakni, simply start the .exe file and click on Start Scan. This will open a file manager where you can select the file that you want to decrypt. It will then start the decryption process.

IMPORTANT: Decrypting files(if the algorhytm allows decryption and is not too strong)may take hours to even days time, depending on the encryption. You should leave your computer working at all time and NOT interrupt the decryption process. In order to do this, you should make sure you change your PC's power settings to not allow it to hybernate or sleep during decryption. To do this, follow these steps.
Step 1: Click on the battery icon in your system tray (next to the digital clock) in Windows and then click on More Power Options.
Step 2:The mighty Power options menu will appear. In your power plan click on Change Plan Settings.
Step 3: In your plan's settings make sure you set "Turn off the display" and "Put computer to sleep" to "Never" from the drop down minutes menu.
Step 4: Click on Save Changes and close it.
Now, you should leave your PC to work it out. Bear in mind that the process may take a lot of time so arm yourself with patience and hope that the algorhytm is decryptable.

Good Luck!
