TrojanDownloader:HTML/Adodb.gen!A is generally an HTML script – a piece of code that can be executed when certain conditions are met. It means that this code might run on the targeted system without the installation of malicious software. This can be particularly dangerous, as security software might fail to detect such behavior.

HTML is a programming language that is often used within a browser environment, and pieces of code can be found on every visited website. However, it can also be used for malicious purposes and, once executed, might be exploited by cybercriminals. Other similar scripts that can be used for malware are:

  • VBS (Visual Basic)
  • JavaScript.

By using this Trojan, threat actors would be able to execute malicious code on the targeted machine. Consequently, they could initiate actions that benefit them,

Users can encounter the TrojanDownloader:HTML/Adodb.gen!A virus after downloading a picture sent via Discord communication app. This software is extremely prevalent, with millions of users worldwide – it is especially popular within the gaming community.

However, malware authors can often abuse the platform for malicious intent to spread Discord viruses around. In fact, this is not the first time that the app was used to deliver malicious files or links that would allow scamming users in various ways. Previously, threat actors were distributing Spidey Bot to steal users' personal information.

When talking of this particular Trojan capabilities, it could allow the attackers to do the same. It could also result in the infiltration of other malware, such as backdoors or ransomware. The latter is particularly dangerous, as it could result in a complete data loss. This is why a timely TrojanDownloader:HTML/Adodb.gen!A removal is so important.

Since the malware is running based on HTML script, it is likely to affect various browsers, including Google Chrome, Mozilla Firefox, Safari, MS Edge, etc. For example, it could be employed by threat actors to steal all the information typed into them. As a result, users could suffer from serious privacy issues or even experience and identity theft.

Luckily, it is unlikely that this malware can actually cause any harm, at least not when security software flags it. Thus, if you saw this threat is detected on your device, you should not ignore it and remove TrojanDownloader:HTML/Adodb.gen!A by sending it to quarantine immediately and deleting all the related files.

If you have any doubts and have reason to believe that the detection is a false positive, you can always perform an additional scan with alternative security software, such as SpyHunter 5Combo Cleaner or Malwarebytes. To fix virus damage, if such has occurred, we highly recommend using ReimageIntego.

TrojanDownloader:HTML/Adodb.gen!A virusTrojanDownloader:HTML/Adodb.gen!A is a malicious program that is usually spread via Discord communication app

Discord is one of many platforms used by criminals to deliver malware

Communication platforms are extremely popular nowadays, as people use them to send private messages, videos, music, and another type of multimedia. Discord is one of the most popular VoIP platforms currently and is especially beloved by gaming and a few other communities. Unfortunately, the prevalence of such apps is constantly being abused by malicious actors, as they use these platforms to deliver malware and scam users into disclosing their personal information.

Therefore, it is always important to know that the communication platforms can be, and will be, used to deliver malicious programs or scripts. To avoid such situations, you should always be aware that a direct message (DM) from an unknown individual should never be trusted. It is important not to click on links that could redirect to spoofing or boobytrapped websites.

In case there is no security software installed, malware could be executed immediately. In some cases, avoiding links might not always be possible, hence you need to employ additional precautions:

  • keep an up-to-date security tool running at all times
  • patch all the software on your machine with the latest updates.

TrojanDownloader:HTML/Adodb.gen!A removal process

As evident, if you have robust security software installed, you should remove TrojanDownloader:HTML/Adodb.gen!A as soon as it is flagged. This is especially important if you have recently clicked on a seemingly innocent link or downloaded a picture or another file to your computer via the Discord app. If not taken care of, the threat could lead to remote code execution by the attackers, who could technically install anything in your machine without you knowing.

If your security software is incapable of performing a permanent TrojanDownloader:HTML/Adodb.gen!A removal (for example, the identification shows up every time) you should perform a full system scan with security software, such as SpyHunter 5Combo Cleaner. Since the malicious script is written in HTML, it is also important to clean all your web browsers to ensure that no leftovers are present on the device. If the virus managed to break into your device already, you should eliminate it and then scan it with PC repair tool ReimageIntego for best results.

How to prevent from getting trojans

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
