Qakbot virus removal guide
What is Qakbot?
Qakbot (also known as Qbot) is a banking trojan designed to steal personal information. Cyber criminals proliferate this virus using spam email campaigns. These emails are delivered with malicious attachments (Microsoft Office [typically Word] documents) that are presented as various important documents (bills, invoices, and so on). Criminals attempt to trick users into opening these files, which then leads to infiltration of Qakbot. In most cases, spam emails are sent via the Geodo (Emotet) botnet.
As mentioned above, Qakbot is a banking trojan and steals credentials of users' bank accounts. These viruses record keystrokes, web browsing activity, saved cookies, logins/passwords, etc. Collected data is saved to a remote server and, therefore, developers gain access to users' accounts. These people aim to generate as much revenue as possible. Funds in the hijacked accounts are used to carry out direct funds transfers, online purchases, and so on. In addition, bank accounts are often used to confirm people's identities. Note that many people use identical logins/passwords for multiple websites. Therefore, criminals might gain access to users' accounts on social networks, emails, etc. Therefore, the presence of Qakbot malware can lead to significant financial loss, privacy issues, or even identity theft. Qakbot is often hidden and difficult for regular users to detect. Therefore, if you have recently opened any attachments received from suspicious/unrecognizable addresses and you suspect that Qakbot (or other malware) has infiltrated your computer, immediately run a full scan using a legitimate anti-virus/anti-spyware suite and eliminate all detected threats.

To eliminate Qbot virus our malware researchers recommend scanning your computer with Spyhunter.
There are dozens of trojan-type viruses that share similarities with Qakbot including, for example, Adwind, TrickBot, LokiBot, FormBook, and Hancitor. These viruses are developed by different cyber criminals and, thus, their behavior might also differ slightly: some record information, proliferate other viruses, etc. Note, however, that all pose a direct threat to your privacy and browsing safety. Therefore, eliminating malware such as Qakbot is paramount.
How did Qakbot infiltrate my computer?
As mentioned, Qakbot is proliferated using spam email campaigns. When opened, the malicious attachments request permission to enable macro commands, otherwise the content will supposedly not be opened. Enabling them grants permission for the attachments to run malicious macros. These commands connect to a remote server and download an executable file, which is placed in the "%TEMP%" folder. The filename typically comprises a few random digits (e.g., "914.exe"). This file then runs and injects malware into the system. The process copies content from a legitimate Windows Calculator executable ("calc.exe") and overwrites the downloaded executable with the copied content. This is done in an attempt to avoid being detected by anti-virus suites. In fact, the infection cannot occur without the users' involvement - the user must trigger the infection manually by opening the attachment. At time of research, cyber criminals distributed an MS Word document that did not contain a .doc or .docx extension (users needed to append it manually).
How to avoid installation of malware?
To prevent this situation, be very cautious when browsing the internet. Never open any email attachment that seems irrelevant, or if the sender seems suspicious/unrecognizable. Bear in mind that criminals abuse users' curiosity by sending various deceptive messages, such as "you have won a lottery", "you have received a package", etc. This is called 'phishing'. Do not fall for these messages in which there are no free offers or rewards. These emails are a scam. Furthermore, have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate malware before it does any harm. The main reasons for computer infections are poor knowledge and careless behavior - key to safety is caution. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Spyhunter for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. 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. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
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.
