Norvas virus Removal Guide

What is Norvas ransomware?

Norvas is the ransomware that encourages victims to pay the ransom by lowering the price as other recent STOP virus versions

Norvas ransomwareNorvas ransomware is the virus that tricks victims into paying the ransom with a 50% off discount. Norvas virus – ransomware that marks data with .norvas appendix when the original code of the file gets changed. This process is called encryption, and it is the primary purpose of such malware.[1] However, cryptovirus has more functions than the file-locking itself. Since this is a version of a well-known Djvu ransomware, it hails from the family of STOP ransomware.

Norvas files virus has been quite active since its release, so there is no surprise that cybersecurity experts are working on the decryption key which is highly awaited by the virus victims. Thanks to Michael Gillespie, you can try using STOPDecryptor to recover encrypted files. However, some users claim that the tool is working only with Offline ID keys.

The one significant similarity between other versions from the same virus family is the ransom note – _readme.txt. It gets delivered together with the same message offering to 50% off discount for the ransom. Filename and the content haven't changed since March. However, the thing that keeps changing is contact information. Norvas virus developers can be contacted via, emails. However, we are not recommending to reach these people since it may lead to data loss or infiltration of more significant malware.[2]

Norvas ransomware virus is the cyber threat that focuses on encrypting pictures, documents, databases, video, audio files or even data stored on a cloud service. When the encoding process goes as planned .norvas extension marks every file that got affected. It indicates which data became useless and unreachable.

The file encryption is the first but not the only process that Norvas ransomware performs on the affected machine. When data gets locked, ransom note gets delivered in every folder containing encrypted files and the _readme.txt file shows the following message:

Do not worry my friend, you can return all your files!
All your files are encrypted with the unique key.
Decrypt tool for you.
This software will decrypt all your encrypted files.

However, after that Norvas ransomware focuses on system alterations. To ensure the prominent infiltration, this threat alters existing registry keys or even adds new, so every time the machine is reloaded the malware runs uninterrupted. Also, adding or removing those meanings can affect processes like security programs and AV tools.

Norvas ransomware virusNorvas ransomware is the cryptovirus that gives 72 hours for victims or the ransom goes from $490 to $980. However, paying the ransom doesn't guarantee the data recovery.

All of these changes make Norvas ransomware removal difficult and makes victims believe that paying is the only solution. Unfortunately, paying the demanded amount may not help with your files because often cybercriminals as such disappear after the payment and data remain locked and useless. Experts[3] note that paying shouldn't be considered as a first option.

Although Norvas ransomware is not much changed from the other versions in the family, developers have unique features added to every new variant. This time, in the ransom note cybercriminals note their Telegram account handle @datarestore and this way offers victims to contact malware creators.

Avoid any contact between you and virus developers because these criminals can send you a file with malicious script and infect the system with other malware or demand more money. You better remove Norvas ransomware with anti-malware tools and then focus on data recovery.

For data recovery, you either need file backups on an external device or cloud service or file restoring software. Make sure to remove all Norvas ransomware virus damage, fix possible issues and clean the system thoroughly with FortectIntego. Then your files cannot get affected by the ransomware again.

Norvas virus decryption?

Data recovery after Norvas ransomware removal can be achieved with data backups, file recovery software or similar tools and features. Also, STOP virus decryptor can be helpful for virus decryption because researchers keep an eye on these virus developers and their activity. Malware victims submit samples and ID keys, so more victims can get help. This tool works for Offline ID: 1OcNMvbG9a2vBz0BdsXRX88kjuVX9ku4EmR64St1 with .norvas file appendix.

When the version of a virus that affected your machine is newer than the researcher submissions the tool may not work at first. Especially when Spring 2019 is a busy time for developers behind this malware because they release a new version every week or so. In the meantime, while you wait for the needed update, you should focus on learning about the particular threat and trying to remove Norvas ransomware from the machine.

Norvas virus decryption toolNorvas ransomware gets a decryption tool when STOP virus decryptor gets an update.

Spam emails containing infected attachments distribute malware

Exploiting system vulnerabilities, using exploit kits or installing harmful software can also be considered ways to spread cryptovirus. However, the primary technique still is considered to be spam emails and macro-filled documents as attachments.[4]

Malicious actors send emails with forged information tricking users into believing that the email is from a company like DHL, FedEx, or eBay and contains important financial information. However, the minute received email gets opened and attachment downloaded on the computer, the malicious script gets loaded on the system.

Notification may claim that the package is not coming to you and you can see all the details if you pres enable the content on the PDF file or a link. When you do so malicious macros get triggered, and the computer gets infected with direct ransomware or malware designed to spread crypto malware further.

If you want to avoid such infiltrations, you should pay more attention to emails you receive and open. Clean the email box more often and delete emails you weren't expecting to get or that seem suspicious and contains questionable attachments.

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.
