VO_ virus Removal Guide

What is VO_ ransomware virus?

Crucial information about VO_ ransomware virus

The good news is that VO_ virus might not be as dangerous as Locky which recently rampaged on the social media [1]. Since only several versions of this malware have been detected, many speculations arise about the capabilities of the ransomware. Once this misfortune befalls your computer, all personal and important files get locked up. What is more, they might all bear .vo file extension. We recommend starting VO_ removal right away. As it is little known about the virus, delaying the process might cause even more severe outcomes. One of the practical tools to speed up the process is to install an anti-spyware program, such as FortectIntego.

Luckily, not all emerging file-encrypting viruses are as hazardous as ransomware titans, for instance, Cerber virus or CryptoLocker which keep inspiring hacker-wannabees. Speaking of VO_ malware, it follows the manner of encoding the data with AES algorithm. It has been mainly used by National Security Agency to encipher the secret documents. Unlike stream ciphering, the main feature of AES is to encode the data by running several repeated cycles of block encryption [2]. If ransomware states that it has employed a AES-128 code, it means that 128-bit key comprises the algorithm formula. Such encryption method proves to be effective in IT cyber security field as well as in a hacking world. Felons, shifting to this method, make extra guarantees that even if victims are computer literate, they would not decrypt files without their “assistance.” At least, they want you to think so. Considering such psychological terror techniques, you should not trust VO_ ransomware hackers as well. The absence of clear instructions of decoding the files leaves room for speculations that this malware might be just a beta version of a more developed virus appearing in the future. In any case, remove VO_ virus right away.

The dangers of VO_malware

When did my computer get infected with the ransomware?

Spam and phishing perform the role of a haven for a variety malware, including banking trojans, ransomware, and extortionware [3]. The latter also possesses the same features as ransomware, but it is more oriented at blackmailing victims [4]. Getting back to the topic of this article and specifically, VO_ hijack, note that it might cover under the disguise of fake delivery email. Gearheads are quite crafty in devising officially looking emails. The ransomware payload might even get delivered in the email which is supposedly sent from Amazon [5]. Likewise, check your system for any adware files as well. A while ago, the PUP under the same title hit the internet stage. It might be linked to the current ransomware.

If your files are encrypted by VO_, you can use several methods to restore them:

How practical is Data Encryption Pro?

If you haven’t backed up your data, and haven’t saved copies of your most important data elsewhere, then, this utility might be one of the last chances to restore the data.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by VO_ ransomware;
  • Restore them.

Windows Previous Versions feature – alternative to restore your data?

How to prevent from getting ransomware

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.
