JS:Agent-EGF
JS:Agent-EGF is malware that is based on JavaScript

JS:Agent-EGF is a type of malicious software that uses JavaScript[1] (JS) to perform its actions. The malware can be obtained when visiting malicious or hacked websites, although victims reported that the infection occurred after they opened a malicious attachment in the spam email.[2] Hackers often employ social engineering to make users click on a malware-laden link. Once executed, JS:Agent-EGF [adw] performs changes to the system and starts downloading other malicious files, such as trojans or cryptominers. This malicious activity can download and install virtually anything, so it is vital not to ignore warnings from anti-virus software.

Category Malware
Type Trojan downloader
Distribution Malicious websites, spam emails
Symptoms Usually none, but users might experience system slowdowns, crashing programs, etc.
Elimination Use potent security software
Optimization Scan your device with Reimage

Once the JS:Agent-EGF virus is installed, it will contact a remote server that is controlled by hackers. This provides the opportunity to malicious actors to run scripts via Windows desktop, Windows Explorer, and Windows command prompt. Unfortunately, JS-based malware is often very hard to detect unless adequate security software is used. After JS:Agent-EGF removal, we recommend scanning the system with Reimage to recover from virus damage.

Due to modification to Windows Registry,[3] JS:Agent-egf [adw] can also read and send out the information that it acquires through the compromised computer. Therefore, such details as banking information, logins to various accounts might be compromised.

While in most cases users will not see any changes to their PCs after clicking on a malicious JS Agent EGF file, in some cases, victims can experience the following:

  • Slow operation of the computer;
  • The appearance of new programs that were not installed by the user;
  • Crashing applications;
  • Random system restarts;
  • Frequent BSoDs;
  • Redirects to suspicious websites when using Google Chrome, Internet Explorer, Mozilla Firefox, or another browser.

Be aware that symptoms might vary, or be not present at all. Therefore, if you think that your machine might be infected with JS:Agent-EGF, you should immediately install security software and perform a full system scan. Powerful anti-virus software will be able to remove JS:Agent-EGF relatively quickly.

Install powerful security software and patch your system to prevent infection

As we already mentioned, this particular threat mostly uses malicious websites to enter users' computers. Nevertheless, it can also be spread with the help of spam email attachments or links, as well as by abusing old system vulnerabilities.

Therefore, it is vital to perform the following steps in order to avoid the infection of trojans and other malware:

  • Download and install robust security software that would be able to stop the threat before the malicious script is run;
  • Make sure your operating system and other applications are updated with the latest security patches;
  • Stop JavaScript by running automatically and enable click-to-run function so you would know when JS is being executed;
  • Do not casually open spam emails or click on links;
  • Backup your files regularly;
  • Avoid visiting file-sharing and torrent sites – these often host malicious files.
