Lanset virus Removal Guide

What is Lanset ransomware?

Lanset ransomware – a well-developed malware which carries the roots of Djvu (STOP) virus

Lanset ransomware virusLanset ransomware is a family member of Djvu (STOP) malware

Lanset ransomware is a highly-developed threat that relates to the infamous Djvu file-encrypting virus. As you might already know, these threats also belong to STOP ransomware which also is well-known malware between the cyber society members. Djvu ransomware has been releasing numerous new variants and Lanset virus is one of them. This threat encrypts files with unique codes,[1] appends the .lanset extension to each file, and displays the _readme.txt text file. The ransom price is the same as for every Djvu-related version, it can be $980 or $490 if contact with the criminals is made in three days. Furthermore, hackers provide an offer of sending them one small file for free decryption as evidence of the decryption key's true existence and a way to attract victims to proceed with payments faster.

Lanset ransomware can be even more complex than some people believe it is. File-encrypting might not be the only activity that this cyber threat relates to. Ransomware infections might destroy Shadow Volume Copies[2] of these files and make the decryption process very hard to achieve even for highly-advanced computer specialists.

Email spam campaigns distribute malware widely

Tech experts from[3] claim that ransomware viruses and similar threats have the biggest chance of appearing on users' computers through spam messages and their attachments. This type of technique usually brings success to the hackers as there are numerous users who lack cautiousness when dealing with received email.

The most important thing is to carefully manage all email letters that you receive and make sure that all attachments or hyperlinks that you are opening do not signal about anything malicious. Another way how ransomware distributes is through outdated programs, fake Adobe Flash Player updates, secondary downloading hyperlinks, etc.

We strongly recommend each user to put up their computer's safety first while completing browsing actions. The best thing would be that every computing activity would be followed by antivirus backup. This way you will be sure that your browsing is secured and that no threats will enter the system without the antimalware informing you about uncommon objects.

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.
