Trojan:JS/Cryxos (Virus Removal Guide) - Tech Support Scam

Trojan:JS/Cryxos Removal Guide

What is Trojan:JS/Cryxos?

Trojan:JS/Cryxos is the threat that delivers notification messages about computers' or web browsers' issues that the virus triggered

Trojan:JS/CryxosTrojan:JS/Cryxos - the tech support scam that shows fake system alerts about, in most cases, unexistant issues. Trojan Cryxos – an infection that displays alerts with phone numbers and offerings to assist in removal processes. This is a support scam that aims to trick people into calling the shady support number or contacting the alleged technicians' team in different ways. Nevertheless, there is no need to call the number or ask for help from these people because this trojan does not alert about real issues. This is a pure scam aiming to get money or sensitive information from victims.

This infection typically can be triggered after opening a malicious site with a dangerous JavaScript or when downloading the file from an insecure email notification. Trojan:JS/Cryxos virus shows notifications to trick people into thinking that their device is infected and that there are some risks or even serious damage the reported virus can cause. This infection is reported by various sources[1] because AV tools detect[2] the intruder that aims to make a profit for the creators. The machine is not compromised even though alerts and warnings state so.

Calling the given phone number can lead to serious infections and hard-to-remove malware infiltrations. Remember that Apple, Microsoft, and other software developers DO NOT send such messages and system alerts to your web browser or desktop in general. None of them offer help via a particular phone number. This fact should encourage you to question such messages like Trojan:JS/Cryxos alerts that are not legitimate or related to any serious security risks.

Distribution Compromised websites, rogue programs, advertisements, and unwanted applications can trigger the infection that shows fake error messages and system warnings
Elimination You can remove Trojan:JS/Cryxos and other intruders by running the anti-malware tools or reliable security programs that can help you with serious infections
Repair The infection can trigger issues with the system when certain files get added or altered. Such damage may disrupt the performance of the computer, so run FortectIntego to see if any problems can get fixed

Trojan:JS/Cryxos messages might vary in languages because some variants open the web browser page that displayed an alert resembling the legitimate Microfost message to enhance the impression about the legitimacy of this alert. Many versions of the fake alert can surface the desktop of yours.

It is not surprising because Trojan:JS/Cryxos creators aim to achieve their goals no matter what. The main indication that such messages are false – phone numbers and encouragements to contact people directly. Legitimate vendors do not do that. Real alerts from the system do not come with contact information or suggestions to remove the infection.

A possible version of a fake error message that Cryxos trojan shows on the screen:

Windows Security
Microsoft Edge
The server ****** is asking for your user name and password.

That server also reports:

You may see the resemblance with other tech support scams, a direct scam that relies on using Microsoft name or report about a particular trojan. Trojan:JS/Cryxos is similar to Windows Defender Alert: Zeus Virus, Microsoft Warning Alert, “Microsoft has detected suspicious activity”, and many other scammy messages. These programs can create issues with the system and trigger damage in the functions, so rely on FortectIntego or similar program to repair these issues.

Trojan CryxosTrojan:JS/Cryxos - malware that creates issues when you use to visit compromised sites, infected domains and click on malicious script without noticing. Trojan:JS/Cryxos removal might seem impossible or extremely difficult because the infection itself is not displaying any symptoms that could lead to a particular program or file that can be deleted right away. Manual virus termination is most likely not possible since you should find the particular payload file yourself.

Fortunately, some tools can help you to remove Trojan:JS/Cryxos from the machine and check for the infection that those reports warn about. Based on the file's detection rate from a malicious email that created these issues, you can easily find a tool that finds and terminated the threat.

Of course, the detection name for the Cryxos trojan depends on the database that the selected AV detection tool uses. So you should run a program like SpyHunter 5Combo Cleaner or Malwarebytes to find threats, infections, other security risks. After the system cleaning, such messages should end.

Trojan Cryxos can lead to more serious issues with the machine if you decide to call the provided number or write the email, contact these criminals in other ways. The alleged further assistance that scammers promise can be a conversation with malicious people that aim to receive payments from you directly, so they give the information for you or even rely on remote access tools that can stop malware too. Avoid clicking on such messages and do not contact malicious people.

Cryxos virusTrojan:JS/Cryxos - scam that includes various messages that attempt to trick you into believing that contacting tech support team is the only solution.

The malicious email in such a campaign can lead to serious malware infection

Spam emails often get used for spreading infections like this. It is common because malware creators aim to distribute products widely and quickly. Email notifications trick people into opening the attached file that contains malicious macro viruses or script running the installation directly on the machine.

You can avoid such alerts legitimacy of notifications from unknown senders and pay close attention to files that you open on the machine directly. There are many issues that such malicious emails can trigger. You need to take the fact that many actors aim to land their programs on your system by showing false messages about invoices and order details.

The malicious email can be named as an order confirmation email or the alert about other information. Check the sender and source of the information before you open the email and download the file. Some AV vendors offer to scan the document before downloading that.

How to prevent from getting spam tools

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.
