What is Cockblocker ransomware virus?

CockBlocker ransomware virus acts rowdy. What else is known about this virus?

Questions about Cockblocker ransomware virus

CockBlocker virus may look like a filthy ransomware-type [1] computer program, luckily though, it is merely a scareware [2] application which imitates ransomware working principles in order to extort some money from the victims. Unlike regular ransomware, it does not encrypt the files it finds on the computer with complex algorithms [3], which means that the files remain structurally unchanged. Nevertheless, the virus still marks all files with .hannah file extension to make them look like they have been encrypted. When the “encryption” is done, the virus drops a lock screen with an insulting message in a RansomwareDisplay.exe program window:

Yo file’s been encrypted n**a
Pays me a bitcoin and I unencrypt them fam

This deceptive program displays the list of the supposedly encrypted files and asks to input a decryption code. However, the virus still seems to be in a development process at the moment, since it does not provide information on how to pay the $732 dollar ransom or how to contact perpetrators. Therefore, we assume that you should make CockBlocker removal a top priority task. To remove CockBlocker virus, run anti-malware software. If you do not have it, consider installing ReimageIntego or SpyHunter 5Combo Cleaner. It is believed that this ransomware is going to be improved anytime soon, but in case you become a victim of this malware, do not consider paying the ransom. In quite a lot of cases, victims who pay up never receive the decryption tool. Besides, just recently, ransomware investigators have announced some good news on how to terminate the lock screen and get back the access to the computer. You simply have to enter not_a_backdoor into the blank space provided on the lock screen and hit “Use Decryption Code”.

CockBlocker malware displays a threatening message

How can you get infected with this ransomware?

Your computer might become contaminated with CockBlocker malware if you tend to browse the Internet carelessly, without thinking about general Internet hazards. You must understand that the world wide web offers a lot of interesting content, but it also provides a lot of dangerous content as well. Browsing the Internet notwithstanding the impeding danger is like walking through a minefield. One click on a malicious link or one email attachment can entirely mess up your computer system and take your precious files away from you. If you do not want that to happen, try to stay away from suspicious or vague content online. Especially pay attention to emails that you receive. Never open files sent to you from unknown people or organizations. In many cases, criminals pretend to be someone they’re not, so do not believe that someone is writing to you from Amazon or Paypal before checking sender’s email online [4]. Also, stay away from sites that aggressively ask you to install software updates, browser extensions, add-ons, and similar software. No one should be pushing you to install anything – if someone does, there is a great chance they want to infect your computer with CockBlocker or any other type of malware.

How to remove CockBlocker virus?

CockBlocker removal can be completed using anti-malware tools.

How to prevent from getting Cockblocker ransomware virus

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
