Vapor ransomware removal instructions

What is Vapor?

Vapor is a ransomware virus designed to encrypt victims' files and make ransom demands. Vapor developers use an AES cryptography algorithm to encrypt files. Once files are locked, they become unusable. Vapor renames each encrypted file by adding the ".Vapor" extension. For example, "1.jpg" becomes "1.jpg.Vapor", and so on. This virus is also designed to display a ransom demand pop-up window with a timer.

The pop-up window informs Vapor victims that all private data, files, cookies, applications and other information has been encrypted with strong (AES) encryption. According to Vapor developers, the only way to decrypt files is to contact them via the email address. Note that criminals generally use a Gmail account. This shows their ignorance and lack of experience, since using a public email service (such as Gmail) to make ransom demands is a great way to get caught. Victims are required to provide a unique client ID so that cyber criminals can recognize the individual (a client ID is provided in the pop-up window). According to Vapor developers, once the victim makes contact, they will send a key for successful decryption. Note that they will not provide this free of charge. Furthermore, they urge victims to contact them within 48 hours. If this does not happen, the files will supposedly be deleted when 48 hours has elapsed, or when the computer is restarted or the ransomware process is killed. Clicking the "I GIVE UP" button will also result in permanent data loss. Therefore, the only option Vapor victims are provided with to retain data stored on their computers is to contact cyber criminals within the time frame. Note that ransomware developers cannot be trusted. They ignore victims even if they receive ransom payments (usually in Bitcoins). Unfortunately, at present, there are no tools capable of decrypting Vapor-encrypted files free of charge. Cyber criminals generate unique decryption keys for victims and store them on remote servers that they control. In such cases, the best solution is to restore files using existing backups.

Most ransomware-type viruses are very similar and serve the same purpose. Some examples of other viruses of this type are Bear, DataWait, and BlackHat. These infections encrypt files and make ransom demands. Generally, the only differences between them are the ransom amount and cryptography algorithm used to encrypt files. Unfortunately, these infections cannot be cracked (unless the virus is not fully developed or contains flaws/bugs). Therefore, victims are encouraged to contact cyber criminals and risk being scammed. Ransomware viruses are just one reason why we recommend that you maintain backups regularly and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

It is not known exactly how cyber criminals proliferate the Vapor virus, however, it is likely that they use spam email campaigns, trojans, fake software updaters, or untrustworthy software download sources. Spam campaigns are used to proliferate viruses by tricking people into opening malicious attachments. Cyber criminals send emails with attachments (or links) that, once opened, download and install viruses. The attachments are usually Microsoft Office documents, archive files, executable files, PDF files, and so on. Trojans infect systems simply by proliferating other viruses - they are malicious programs that cause chain infections. If a trojan is installed, it is likely that this is how the ransomware infection was caused. Fake software updaters are tools that download and install infections rather than the updates, or exploit bugs/flaws of outdated software. Various untrustworthy software download sources can also be used to infect computers. Typically, these are free file hosting and freeware download websites, various peer-to-peer networks (torrent clients, eMule, etc.), and other unofficial sources. Cyber criminals use them to present various executables (or other malicious files) as legitimate and trick people into downloading and installing viruses.

Threat Summary:
NameVapor virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll 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 Vapor virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Be careful when browsing the web, downloading, installing, and updating software. Emails that contain attachments (files or links) and are sent from unknown/suspicious addresses should be carefully studied. Do not open an attachment (file or link) if you suspect that the email is irrelevant or suspicious. Do not download/install software using third party downloaders or installers, since these tools are often monetized by promoting untrustworthy/rogue applications. Download software using official, trustworthy sources and using direct links only. Keeping software updated is important, however, this should be done using tools or functions provided by official software developers only (this does not include various third party updaters). Have reputable anti-virus/anti-spyware software installed and enabled at all times - this increases the chance that viruses are detected before they can do any harm. If your computer is already infected with Vapor, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Text presented in Vapor ransomware pop-up window:

Vapor Ransomware
You Have Been Caught.

You Cannot Run
You Cannot Hide
You Aren't Safe Here.

What happened To Me?

All your private data, files, cookies, application and much more as been encrypted into a strong encryption!
The only way to get it back is by sending a support email at this email:

Please make sure your Client ID is included so we can recognise you and send back the key.
When its done, enter the key into the key box and enjoy your day / night.

You have 48 hours to send the email, if the timer runs out your files will be deleted.
If you restart the PC or kill the program, you will never be
able to get your files back since they will be re-encrypted if you re-launch the program.
Basically closing the program in anyway will result in loosing the key.

- Good Luck, Good Time.
