BonziBuddy virus Removal Guide

What is BonziBuddy ransomware virus?

The outcomes of BonziBuddy ransomware attack

Among the newly emerged ransomware threats, BonziBuddy virus might cause various associations. Despite its title, which is borrowed from famous interactive application distributed between 1999 and 2004, it is unwise to underestimate it. The PUP version, which spread under the Win32.adware-gen a few years ago, received attention as well. However, this cute virtual character did not cease to inspire cyber criminals. It disperses with the assistance of a trojan horse. Furthermore, evading it turns out to be a challenge. Fortunately, you can remove BonziBuddy if you employ a reliable application, such as FortectIntego. Since the ransomware spreads with an entire escort of malicious files, the elimination process should not be delayed. More explicit information about BonziBuddy removal is delivered below the article.

Pop culture, mythology, and political events spark cyber criminals’ imagination to give specific and peculiar names for the menacing file-encrypting malware. As the international virtual community still battled the latest version of Cerber and Thor, this name of this virus also originates from a popular application. This Windows assistant gained popularity in the turn of the millennium by guiding users throughout the web and their browsers. Unfortunately, the innocent image of purple gorilla was exploited for hackers’ misdeeds.

According to the ransom message, the crooks are suspected to be a bunch of amateur hackers still making their way into the ransomware business. As a result, they did not perfect their creation. The ransom message is not elaborate as it only mocks victims by throwing offensive remarks. There is no indicated email address or explicit instructions to recover the files. What is more, they are unaffected as BonziBuddy malware does not employ standard AES-128 or RSA-1024 encryption techniques. In addition, the ransomware does not limit your access to the device. It might be similar to Smash! ransomware and zScreenLocker which did lock the screen but did not inflict bigger damage. However, its distribution method might cause concern for the members of the virtual community.

How do hackers disperse the malware?

The malware has been detected spreading via the following trojans:

  • Ransom-Joke.BonziBuddy
  • W32.Troj.Ransom.Filecoder!c
  • Win32.Trojan-Ransom.Filecoder.P@gen
  • Win32:Malware-gen

Therefore, this situation suggests that the initiators of BonziBuddy ransomware have huge potential to improve their viruses in the future. You should arm up with proper security tools to reduce the vulnerability of your operating system. Keep in mind that other ransomware viruses tend to spread via spam messages. The crooks have mastered the techniques how to forge realistic and persuasive fake FBI alerts or trial invitations, though usually the victims are bombarded with fake package delivery and invoice attachments. Recklessly reviewing them might activate BonziBuddy hijack or trigger the infiltration process of another virus. Regardless if the message addresses you directly, do not fall for such bait. Curiosity might cost you the personal data!

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
