Also Known As: Trojan.win32.adject.gen virus
Type: Trojan
Damage level: Severe

What is Trojan.win32.adject.gen?

Trojan.win32.adject.gen is deceptive malware that infiltrates the system and modifies the content of visited websites. Note that, unlike adware-type applications (which have similar behavior), Trojan.win32.adject.gen cannot be seen in the list of installed applications, browser extensions, etc.

Therefore, distinguishing and eliminating this threat is more difficult as compared to regular adware.

Trojan.win32.adject.gen malware

Immediately after infiltration, Trojan.win32.adject.gen modifies visited websites by injecting them with malicious JavaScript/HTML code - this modifies  website content. Users are presented with various advertisements (banners, coupons, pop-ups, etc.), and links that overlay the content of the site. Therefore, Trojan.win32.adject.gen significantly diminishes the browsing experience.

Furthermore, users might encounter redirects to other malicious websites and Trojan.win32.adject.gen might inject/execute scripts that stealthily download and install other malware into the system. Therefore, the presence of Trojan.win32.adject.gen can lead to chain computer infections.

Infiltrated malware might perform a number of actions, including information tracking, file encryption, cryptocurrency mining, and so on. Therefore, your privacy and computer safety is at risk. As mentioned above, Trojan.win32.adject.gen hides its tracks well - it does not appear in any list of installed applications or browser plug-ins.

Fortunately, many reputable anti-virus/anti-spyware suites are capable of detecting and eliminating this virus. Therefore, if you encounter suspicious web content/redirects, you should immediately scan the system and remove all detected threats.

Although Trojan.win32.adject.gen is not classed as regular adware, its behavior is very similar. Most adware infections claim to be legitimate apps, rather than hiding (as with this malware).

By offering various "useful features", adware-type apps often attempt to give the impression of legitimacy, however, since their only purpose is to generate revenue for the developers, most provide no real value for regular users. Adware-type apps deliver intrusive advertisements and (in most cases) gather various information.

How did Trojan.win32.adject.gen infiltrate my computer?

It is currently unknown which exact method is used to proliferate Trojan.win32.adject.gen, however, criminals typically distribute these viruses using spam email campaigns, trojans, peer-to-peer (P2P) networks, unofficial software download sources, and fake software updaters.

Spam campaigns are delivered with malicious attachments (usually MS Office documents) that, once opened, stealthily download and install malware.

Trojans open "backdoors" for other viruses to infiltrate the system. P2P networks (eMule, torrents, etc.) and other third party download sources (free file hosting websites, freeware download websites, etc.) present malicious executables as legitimate software. In this way, users are tricked into downloading and installing malware.

Fake software updaters infect the system in two ways: 1) by exploiting outdated software bugs/flaws or; 2) downloading and installing malware rather than updates. Ultimately, the main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the Internet and downloading/installing/updating software. We strongly recommend that you think twice before opening email attachments. Files that seem irrelevant or have been received from suspicious/unrecognizable email addresses should never be opened.

It is also very important to download your programs from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should never be used. Furthermore, keep installed software up-to-date, however, to achieve this, use implemented features or tools provided by the official developer only.

Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. The key to computer safety is caution. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

manual malware removal step 5Check the list provided by Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the file of the malware, remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
