More examples of Trojans that are designed to steal confidential information and/or do other things are KBOT, Lampion and CryptBot. In most cases Trojans are designed to steal various information and/or infect operating systems with some other malware (e.g., ransomware). Either way, cyber criminals spread programs of this type with a purpose to generate. We strongly recommend to take all necessary precautions that would prevent installations of programs of this type.

How did Grandoreiro infiltrate my computer?

Cyber criminals proliferate Grandoreiro through malicious websites that contain videos supposedly related to Coronavirus. However, if a visitor clicks the "Play" button, then those websites download an archive file named "video-china02712.zip" (downloaded file could be named differently) which contains a malicious executable (.exe) file. If opened/executed, that file installs Grandoreiro and allows it to steal personal data. Peer-to-Peer networks (e.g., torrent clients, eMule), free file hosting, freeware download websites, third party downloaders are examples of other file and/or software download channels, sources that can be used by cyber criminals as tools to host malicious files. Unfortunately, there are more ways to spread malware. For example, emails (spam campaigns), fake software updating tools, and unofficial activation ('cracking') tools. Cyber criminals employ spam campaigns as tools to spread viruses by sending malicious attachments via email. They send emails that include infected Microsoft Office documents, archive files, PDF files, executables, JavaScript files and so on, hoping that people will open them. If opened, these attachments (or links) download and install malware. Fake software updating tools infect operating systems by installing malware instead of updates, or by exploiting bugs, flaws of some outdated software that is installed on the operating system. Software 'cracking' tools are designed activate licensed programs for free (bypass their activation). However, quite often they are designed to install various malicious programs.

How to avoid installation of malware?

If a received email is irrelevant, it is sent from unknown address and contains some attachment (or website link) it should be ignored. We strongly recommend not to open files (or web links) that are presented in emails of this kind without being sure that it is safe to do that. Software should be downloaded from official websites and direct download links. Other sources (like Peer-to-Peer networks, third party downloaders, unofficial pages, etc.) could be used to proliferate malware. Installed programs should be updated through implemented functions or tools that are provided by official software developers. The same applies to their activation. It is illegal to use third party tools to activate licensed programs and it may lead to having a system infected with malware. And finally, it is important to regularly scan the operating system for threats with a reputable antivirus or anti-spyware suite and always keep it up to date. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

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 filename of the malware, be sure to 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 Spyhunter for Windows.
