FedEx Invoice Ready email virus removal guide

What is the FedEx Invoice Ready email virus?

Malspam campaigns are usually disguised as official messages from legitimate companies and organizations, and contain an attachment or website link designed to download a malicious file. The main aim of cyber criminals behind such emails is to deceive the recipient into executing a file that infects the computer with a malicious program. This malspam campaign is disguised as a message from FedEx and is used to distribute malicious software called Dridex.

This email is disguised as a message regarding an invoice from FedEx. It contains a malicious Microsoft Excel document which installs Dridex. Note that these documents infect computers only if users enable editing/content (macros commands). This does not apply to documents that are opened with MS Office versions that were released before Microsoft Office 2010, which enable macros automatically. Dridex (also known as Bugat and Cridex) is capable of logging keystrokes (recording keys pressed on the keyboard). In this way, it functions as a 'keylogger'. Generally, cyber criminals use malware of this type to steal sensitive information (such as login credentials, credit card details), which can be used to steal identities and personal accounts, make fraudulent purchases and transactions, and for other malicious purposes. Additionally, Dridex can execute inject code into specific software programs to modify their behavior. For these, reasons you are strongly advised not to open or execute files attached to emails such as this, or files that are available through links within them.

How did "FedEx Invoice Ready Email Virus" infect my computer?

In this case, Dridex gains permission to be installed if recipients open the attached Microsoft Excel document and enable macro commands (editing/content). As mentioned, malicious documents that are opened with versions older than MS Office 2010 infect systems automatically, since these versions do not include "Protected View" mode. Some examples of other files that cyber criminals attach to their emails when distributing malware are JavaScript files, executable files (.exe), archive files such as ZIP, RAR, PDF documents or other MS Office documents (like MS Word).

How to avoid installation of malware

Emails that are received from unknown, suspicious addresses, are irrelevant, and contain an attachment or website link, should never be trusted. Commonly, these emails are disguised as messages from legitimate companies. In fact, they are sent by cyber criminals who attempt to distribute malicious software. Files or programs should not be downloaded or installed through third party downloaders, installers, unofficial websites, Peer-to-Peer networks (torrent clients, eMule) or other sources/tools of this kind. Commonly, these channels are used to distribute malware. The safest way to download files and programs is to use official websites and direct links. Installed software must be activated and updated with tools or functions that are provided by the official developers. Third party, unofficial tools should never be used. Furthermore, it is illegal to activate licensed software with unofficial ('cracking') tools. Keep computers safe by regularly scanning them for threats with a reputable antivirus or anti-spyware suite, which should be kept up to date. If you have already opened "FedEx Invoice Ready Email Virus" attachment, we recommend running a scan with Combo Cleaner Antivirus 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.

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