Kokoklock ransomware removal instructions
What is Kokoklock?
Kokoklock is software categorized as ransomware. This malicious program was discovered by GrujaRS. Ransomware-type programs encrypt files with strong encryption algorithms. To regain access to their files, victims are encouraged to buy a decryption tool and/or key from the cyber criminals who designed the ransomware. Kokoklock renames all files by adding an email address and a random extension to the filenames. For example, "sample.jpg" might be renamed to a filename such as "sample.jpg.mailto[email@example.com].1a9296". The filename of the text file containing the ransom message has the same format as the extension added to all encrypted files. In this case, the text file would be named "1A9296-Readme.txt".
According to the ransom message delivered by these cyber criminals, Kokoklock encrypts all files. To receive instructions about how to decrypt them and/or pay the ransom, victims must send an email to Kokoklock developers using firstname.lastname@example.org or email@example.com. The email must include a personal ID/ code, which is appointed to each victim individually. This code can be found at the bottom of the ransom message. Additionally, victims are permitted to attach one file that cyber criminals will decrypt free of charge. Typically, only the cyber criminals who designed the ransomware can decode files encrypted with their ransomware. Unfortunately, this is the case with Kokoklock ransomware. These programs lock files using strong encryptions that are usually impossible to 'crack. Never trust cyber criminals, since there is a high probability that they will not send decryption tools or keys even if they are paid. People who trust them are often scammed. Generally, the only free way to recover lost files is to restore them from a backup.

Kokoklock is similar to many other programs of this type such as .cmd, Peta, and Shariz. These programs prevent victims from accessing their data so that cyber criminals can force them to pay ransoms (purchase decryption software and/or keys). Two main variables are cost of decryption (ransom size) and cryptographic algorithm (symmetric or asymmetric) used to encrypt data. Typically, decryption without a help of cyber criminals is impossible, unless ransomware is not complete, has bugs/flaws, and so on. To avoid data and possible monetary loss in future, we recommend have data backed up and store it on a remote server such as Cloud or an unplugged storage device.
How did ransomware infect my computer?

|Ransom Demanding Message||Email address and a string of random characters.|
|Cyber Criminal Contactfirstname.lastname@example.org, email@example.com|
|Detection Names||Avira (TR/Crypt.XPACK.Gen), BitDefender (Gen:Trojan.Heur.FU.euW@aqmXl0f), ESET-NOD32 (A Variant Of Win32/Filecoder.NXP), Kaspersky (Trojan.Win32.DelShad.aqi), Full List Of Detections (VirusTotal)|
|Symptoms||Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand payment of a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads, unofficial software activation or updating tools.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections
Do not open attachments that are included in emails received from unknown/untrustworthy addresses. Generally these are presented as official, however, they are not relevant to the recipients. To safely update installed software, use implemented functions or tools provided by official developers. Files or programs should not be downloaded from untrustworthy/unofficial websites, third party downloaders, or other channels as sources. The safest way to download is using official websites and direct download links. Software 'cracking' often infect systems with malware and are illegal. Do not activate any programs with them. Scan the operating system for viruses regularly using reputable anti-virus or anti-spyware software. If your computer is already infected with Kokoklock, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Kokoklock ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Kokoklock ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Kokoklock are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Kokoklock ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
