Grandoreiro virus removal guide
What is Grandoreiro?
Grandoreiro is the name of a malicious software that is categorized as a banking Trojan. Cyber criminals attempt to infect computers with software of this type so they generate revenue by misusing information that programs like Grandoreiro are designed to steal. Trojans of this type steal banking-related information, which means their victims are exposed at risk of monetary loss. If a computer is infected with Grandoreiro (or any other malicious program), then it should be uninstalled/removed immediately.
Typically, banking Trojans are designed to steal information such as login credentials (logins, passwords), account numbers, credit card details, and other confidential information stored or processed through various online banking systems. Cyber criminals misuse stolen information to generate revenue by making fraudulent purchases, transactions, selling it to third parties and in other ways. In one way or another, they misuse those details for financial gain, they attempt to generate as much revenue as possible. In most cases victims of banking Trojans like Grandoreiro suffer a monetary loss, experience problems related to online privacy, become victims of identity theft and other serious problems. If there is a reason to believe that Grandoreiro is already installed on the operating system, then this malicious software should be removed from it as soon as possible.

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".
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.

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.
