What is Dot ransomware virus?
What is known about Dot ransomware virus?
In the middle of the February 2017, malware researchers spotted Dot ransomware virus. This brand new ransomware is still under investigation; however, it is already known that it operates like Ransomware-as-a-Service (RasS). RaaS services gain more and more popularity in the dark web community. It allows wannabe hackers to learn from the experienced malware developers how to develop successful ransomware projects. Meanwhile, developers of the famous file-encrypting viruses generate passive incomes. Talking about Dot virus, it is supposed to behave like an ordinary ransomware. Therefore, it’s purpose is to get inside the computer, encrypt targeted files and demand victim to pay the ransom. Judging from the preliminary information, the virus might also be hiding under the Vanguard ransomware name. However, lack of specific information only allows making assumptions. The name of Dot malware also resembles of .dot virus that has been spotted encrypting a wide range of popular file types with AES encryption key about one year ago.
Dot virus hasn’t started spreading actively; hence, you have time to strengthen your computer’s security and protect your data. The number of ransomware attacks is rapidly growing. As a result, many computer users lose their personal files. Data backups have never been as important as they are now. Sadly, computer users haven’t got used to back upping yet. Nevertheless, cyber criminals always offer to purchase decryption key; victims are advised not to do it. No one can guarantee that hackers provide you active and safe to use software. That’s why we suggest users remove Dot or other ransomware immediately after the attack. Virus elimination won’t rescue encrypted files; however, it prevents from further damage. Affected computers become vulnerable and might be the target of other ransomware and malware. Therefore, you may have to deal with never-ending computer and privacy-related problems. We highly recommend performing Dot removal with RestoroIntego.
Dot ransomware is another file-encrypting virus that demands paying the ransom.
How can I avoid ransomware?
Specific distribution methods are still unknown. However, it seems that developers of the Dot ransomware might be using malicious emails attachments to spread the malware executable known as Core.exe. Sending obfuscated malware executable via spam emails is still a popular and, sadly, effective way to attack computers. Cyber criminals often use fake MS Word documents that might ask to activate malicious Macro commands or install malware immediately. The infected file might be renamed as invoice, statement or other important documents. People should be especially attentive and careful during the tax season or around holidays. What is more, if you want to avoid Dot malware and other ransomware, you should not visit high-risk websites, such as gaming, gambling or adult-themed. Be aware that both potentially dangerous and legitimate sites might deliver malware-laden ads. Hence, avoid clicking ads that inform about detected viruses on your PC, suggests installing software or updates. Often these ads contain malware. Lastly, we highly recommend strengthening your computer’s security by installing reliable antivirus or anti-malware program.

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
