7zipper virus Removal Guide

What is 7zipper ransomware virus?

What do you need to know about 7Zipper virus?

7Zipper virus is a new ransomware-type[1] Trojan that encrypts all files on the target computer and adds .7zipper extensions to them. What is more, this ransomware virus also groups the corrupted data and puts it into 7-Zip archives and protects these with a password. We must point out that the 7-Zip software is entirely legitimate and it is not related to this virus in any way – it simply employs this program for bad intentions. Additionally, 7Zipper ransomware has nothing in common with 7Zipper app[2] in Android store. The virus refers to the victim in the Portuguese language by leaving a ransom note called Saiba como recuperar seus arquivos.txt on the desktop. This text file contains only a few lines of information regarding the computer infection. You can see these lines below.

Para recuperar seus arquivos, entre em contato pelo email enviando sua chave:

zipper@email.tg

The long line of random letters and symbols is victim’s ID number. The line below ways: “To recover your files, contact us by email with your key.” Criminals use an email account that uses Togo country code, which is a slightly strange fact. If you are disposed to contact cyber criminals[3] and start negotiations, we just want to remind you that cyber criminals are as filthy and greedy as real-life criminals. If you contact them via provided email address, you will be asked to buy Bitcoins and send them to offenders’ Bitcoin wallet. We highly recommend you not to do so; criminals rarely keep their promises[4], and instead of providing you with a working decryption tool, they might just infect your computer by providing a software bundle that contains a bunch of malicious programs. Therefore, we highly suggest you remove 7Zipper ransomware using proper malware removal tools (such as ReimageIntego) and use data backups to restore at least part of lost data. You can also find some data recovery options below 7Zipper removal instructions right below the article.

How can I prevent ransomware attacks?

Ransomware viruses never spread in a direct way. Cyber criminals collect thousands of emails and send precisely written email messages to them, adding a malicious file attachment as well[5]. Typically, such file attachments hide malicious scripts that only need Macros function to be activated. You might also receive malicious JS files or simply .exe files. Opening malicious email attachments is never a good idea, and you should delete emails sent by unknown or suspicious-looking individuals immediately instead of looking at their contents. Another tip is to use data backups; although the majority of people did not even consider creating backups in the past, nowadays more and more people create them because of an increased number of ransomware attacks. If you still do not have a backup, you should create one right now. You can find more information on this matter in this post. Finally, we suggest installing trustworthy anti-malware programs for maximum system protection.

How to remove 7Zipper virus?

If your PC got hit by this ransomware virus, you should not ignore it and start taking certain actions immediately. First of all, you should remove 7Zipper ransomware using anti-malware software (or anti-spyware) – just install such program, run a system scan and let it detect malicious files on the system for you. As soon as the scan finishes, delete infectious files with a single click. The reason why we do not recommend manual 7Zipper removal method is that it requires a lot of computing knowledge and playing with system settings and Registry entries can do more harm than good. Therefore, we suggest you follow instructions provided below and start removing this infection right away.

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.
