Kovter virus Removal Guide
Description of Kovter ransomware
Everything you should know about Kovter virus
Kovter ransomware is known for virus researchers since 2013. Then it acted as a police ransomware, but later it changed its strategy, and during 2014-2015 it has arranged many ‘click fraud’ attacks. This year it has been changed one more time. Since the spring of 2016, it has already scammed many computer users and swindled an impressive amount of money from people living in the United Kingdom, USA, Spain, Italy, France, Netherlands, and Germany. Kovter virus blocks access to the computer and delivers a message from various ‘legal’ institutions. The message informs that user’s computer had been blocked due to illegal online activities that are related to child pornography. Once it gets inside the computer, it starts scanning browsers’ history and look for adult-themed websites. If the owner of an infected computer has actually visited a pornographic site, this lock screen with a warning message might scare him or her a lot. However, if malware cannot find any necessary link, it chooses a random pornographic website and uses it against the victim. However, if you receive a warning from FBI, Police or other legal institutions, do not consider paying the ransom. Cyber criminals just want to scam you and swindle your money. Therefore, if you got infected, initiate Kovter removal immediately.
As you may have already understood, malware can scan affected computer’s browsers’ history and collect various browsing-related information, computer’s location, IP address, etc. Kovter virus might also encrypt several files as well; however, they use local file encryption key that makes data decryption quite easy. In the lock screen hackers inform that victims have to pay a ransom in order to unlock the computer and avoid spending several years in jail. The size of the payment varies from 0.5 to 1.5 Bitcoins (around 290-878 GBP). However, paying the ransom neither save you from prison nor help you to get back access to your computer. Instead of thinking about transferring money, remove Kovter immediately.
How does malware proliferate?
Even though Kovter virus slightly differs from other ransomware because it does not concentrate on strong data decryption, it still uses the same distribution techniques. Malicious spam email campaigns stay the main way how malware spreads. Therefore, if you haven’t encountered Kovter ransomware virus and you want to avoid other malware as well, you should not trust every single email that appeared in your inbox. The creators of malware use various methods to convince users to open an attached document. Users always suspect nothing and bravely open an infected Word or PDF document named as an invoice or bank statement. Keep in mind that nowadays hackers do not need sending .exe files that contain virus executable. Ransomware distribution techniques became so advanced that they are hard to avoid. Keep in mind that you cannot trust any email that might be sent from FBI, Police, various governmental and legal institutions. Before opening any attachment or rushing to pay demanded amount of money, double check the information about the sender and the described issue. Feel free to contact that institution directly and look for information about the sender online.

How to prevent from getting Kovter ransomware
A proper web browser and VPN tool can guarantee better safety
As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service.

Reduce the threat of viruses by backing up your data
Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.
It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
