About this threat
HEUR:Trojan-Dropper.Win32.Miner.gen is the detection name for a cryptocurrency miner malware. It’s not the most dangerous piece of malware you can get but it’s not exactly harmless either. Cryptocurrency mining malware aims to infect computers and then use them to mine for cryptocurrency. So if you have an unauthorized miner on your device, it’s using your computer’s resources to mine cryptocurrency for malware creators. While the mining does impact your computer quite severely, it doesn’t actually do damage. So even if you notice mining malware installed, there is no need to worry too much. However, you will have to delete HEUR:Trojan-Dropper.Win32.Miner.gen and the sooner you do it, the better. Until you do, your computer will be sluggish, programs will lag and take a long time to launch, and your device’s general performance will be pretty poor. This is all because a miner is using your computer’s resources. When it’s gone from your computer, everything will return to normal.
People usually pick up mining malware when they download programs/content from questionable sources or click on malicious advertisements. At first, users might not even notice the infection entering, but it soon becomes obvious because of its negative impact on your computer’s performance. We will explain how you can accidentally obtain mining malware, and what you can do to avoid it.
How does the malware enter a computer?
Users usually pick up this kind of malware because of their bad online habits. Users carelessly download from all kinds of sources, click on random email attachments and links, engage with ads, etc. Users who download pirated content are particularly endangering their computers because those sites often host malware. Malware can frequently be encountered on Torrent websites, as well as free streaming pages that host copyrighted content. It’s best to avoid sites that are known to host malware.
You should also be careful about where you download software and updates from. When visiting dubious websites, you might encounter alerts claiming you need to update your software or install some kind of plugin. Keep in mind that programs you have installed will never notify you about an update via your browser. Those alerts are just aiming to trick you into installing some kind of malware. Never download anything from advertisements, particularly ones hosted on questionable websites. If you are offered to download programs by an ad, look into its reputation, and if it’s legitimate, only download it from trustworthy sources.
Spam email attachments are also known to spread malware. Therefore, be careful about which attachments you open when dealing with emails. Generally, spam emails are pretty obvious because they are riddled with mistakes. However, once in a while you might encounter a more sophisticated email. It may claim to come from some legitimate company whose services you are using and try to trick you into opening the attachment. When an email causes even the smallest suspicion, you need to check the sender carefully and scan the attached file with a malware scanner before you open it. The latter with allow you to be sure that what you are about to open is not some kind of malware.
What does the malware do?
Cryptocurrency miners are not exactly dangerous, although they certainly are annoying. They’re also pretty noticeable infections, for those who are aware of the symptoms. First of all, a computer will start acting sluggish, programs may crash and take ages to launch, and you will see strange processes in Task Manager using a lot of your CPU. However, unless you are familiar with cryptocurrency miners, you might not realize what exactly is going on with your computer. The good news is that it won’t harm your computer, even if you do not notice for some time. It will, however, use your computer’s resources to mine for cryptocurrency without your permission, and that is not something you should allow.
If you suspect mining malware to be installed on your computer, open your Task Manager (Ctrl + Alt + Del -> Task Manager) and check the processes running. Look for one that is using a lot of your computer’s CPU. When we say a lot, we mean more than 60-70%. The process should appear at the top of the list. If you see one using that much, you are dealing with a cryptominer. We should note that if you let the miner run for a long period of time, it might shorten your CPU’s lifespan, as it’s not used to running at such high temperatures for long. Thus, the sooner you remove HEUR:Trojan-Dropper.Win32.Miner.gen, the better.
