This segment is the most important piece of education you will ever receive if you are a beginner, because it will briefly teach you how to spot the difference between fake e-mail messages and actual e-mails. This is also due to the fact that the most often cause of infection by .js files viruses is via e-mail attachments. So when we are talking about .js files protection, we are also addressing spam e-mail protection as well.
The first step when receiving an e-mail and deciding whether or not to open a .js file in it is to have a system. Such system is very simple to memorize. If I could summarize it, I would definitely use this sentence:
The “top” is the subject of the e-mail that is sent to you and the source e-mail it is sent from. Here you can sort out the cheap e-mails which you can immediately delete even without having to open them. These are the so-called “promotion” and “important” e-mails that are not from organizations, but different individuals that you have never met before. Usually, people tend to write e-mail topics of something familiar to the user who they are sending the message to. Otherwise, why would have provided your e-mail address to specific people for contact, right?
One solution is to use a sandbox application that “wraps” your web browser or e-mail client (Mozilla Thunderbird, Microsoft Outlook) in a secure encryption on which if the ransomware infection malware is activated, may immediately shut down because it will be stopped inside the program. One very good example for a sandbox application is a neat little app, called Sandboxie which we tested below. It even has the option to auto wrap every program you start in a sandbox automatically without affecting the performance of your computer even the slightest.
However, some sophisticated viruses and malware who run on .js to infect users may be coded and obfuscated with expensive obfuscators and exploit kits that may even go as far as through the sandbox application itself. Here is where you will need an advanced protection tool against these programs when you do your e-mailing – an advanced anti-malware tool is just the thing for you. Unlike traditional antivirus programs, most anti-malware programs are more frequently updated, and they are not just focused on .js malware, but on other suspicious files roaming around in spam e-mails carrying what may just be the lasts Locky or Cerber viruses.
There are a variety of anti-malware programs to choose from out there, and many would argue that the more well-known a security software is, the more it becomes a target for malware, because of the higher interest in it. This is why there should be a balance between a tool on which the hackers have little intelligence while at the same time is frequently maintained and updated. The best choice is a tool that will have a second-generation heuristic update system. This means that if the latest Locky hits in the U.S., the program on your computer should know about this and have the heuristics as fast as possible after this “zero patient” type of infection. One good example for such tool is Heimdal’s professional version, which we have kindly reviewed for you below and in case you do not seem to be fond of it it there are many other tools out there amongst which you can choose.
What If I Don’t Have the Time or Experience To Check Every E-mail?
The idea for this unexpectedly smart solution is that most spam e-mails are designed to trick Windows users into becoming infecting with malware. Surely, there is a lot of malware written for Android, but provided a little education and malware writers prefer malicious URLs via fake advertisements or suspicious apps to infect Android users, not e-mail. More to it than that, Android devices can also be additionally secured from .js files infection with an antivirus software and other utilities and app monitors, which is great. One app that is the leader and is very simple to use (install and start) is called Nox App Player, and after using it, we felt convinced in its stability as well as security
What about Malicious URLs?
What If the Inevitable Happens?
If you are using any of those beginner tools, regularly updating your operating system, etc. and still manage to become infected somehow with a .js files attack, good data management is crucial to your survival from the devastation. Below, you may find more information on how to safely store your important files and protect them from .js files viruses.
Since a lot of malware including ransomware, now may not only slither other viruses on your computer if it becomes its victim, but it may also spread worms or make the computer a part of a botnet (bot network). This makes all of the other computers connected to the same network endangered, and they may not have such defensive tools. This is why, before all, your first deal of business is to disconnect the computer from the internet “the hardware way”. This will prevent any malicious packets to travel on your LAN and infect the other devices in it. From there, you can begin coping with the situation.
