KadrBot virus removal guide
What is KadrBot?
KadrBot (more specifically, Win32:KadrBot) is the name of a threat detected by various anti-virus suites. This threat is categorized as a trojan and hides deep within the system. These viruses typically infiltrate computers without users' permission and their presence can lead to various issues, since trojans are often used to proliferate other viruses and manage systems remotely (criminals use them as remote access tools).
Trojan-type viruses are often used to proliferate other computer infections, such as information-stealing trojans, ransomware, cryptominers, and many others. They also record credit card details, saved logins/passwords, keystrokes, and other similar data. Cyber criminals aim to generate as much revenue as possible. Therefore, they are likely to steal funds from hijacked bank accounts. Furthermore, they can cause privacy issues by stealing victims' accounts. For instance, they can use contacts from social network and email accounts to request money lending. Ransomware-type viruses encrypt stored data and then make ransom demands - to restore their files, victims are asked to pay. Unfortunately, criminals often ignore victims, once payments are submitted. Thus, sending money gives no real value and files remain encrypted. Cryptomining infections significantly diminish system performance and might even damage hardware. Cryptomining can take up to 100% of system resources, thus making computers virtually unusable (they barely respond) and unstable (they are likely to crash). Furthermore, fully-loaded systems generate excessive heat and in certain circumstances (e.g., high room temperatures, bad cooling systems, and so on), hardware components can overheat and become permanently damaged. There is also a high probability that cyber criminals will use KadrBot to perform malicious actions on the infected machine. For example, they may upload/download files, take screenshots, use the webcam/microphone, and so on. Therefore, the presence of a trojan-type virus can lead to serious privacy issues, significant financial/data loss, and permanent system/hardware damage. Note that KadrBot can be installed by other infections. Therefore, if your anti-virus suite has detected this threat, we strongly advise you to perform a full system scan and eliminate all detected threats immediately.
|Threat Type||Trojan, Password stealing virus, Banking malware, Spyware|
|Symptoms||Trojans are designed to stealthily infiltrate victim's computer and remain silent thus no particular symptoms are clearly visible on an infected machine.|
|Distribution methods||Infected email attachments, malicious online advertisements, social engineering, software cracks.|
|Damage||Stolen banking information, passwords, identity theft, victim's computer added to a botnet.|
To eliminate Win32:KadrBot our malware researchers recommend scanning your computer with Spyhunter.
There are many trojan-type viruses that share similarities. The list of examples includes (but is not limited to) DUNIHI, TrickBot, FormBook, Adwind, iTranslator, and Hancitor. The developers are different and the behavior of these infections also differs - some record data, others cause chain infections, etc. Nevertheless, all pose a significant threat to your privacy and computer safety. Therefore, you should eliminate these threats immediately.
How did KadrBot infiltrate my computer?
It is currently unknown exactly how developers proliferate KadrBot, however, trojans are often distributed using spam email campaigns, fake software updaters, software cracks, other trojans, and unofficial software download sources. Spam campaigns are used to proliferate malicious attachments that, once opened, inject malware into the system. Fake updaters infect computers by downloading and installing malware rather than the expected updates or by exploiting outdated software bugs/flaws. The purpose of software cracking tools is to activate paid software free of charge, however, they are often used to proliferate viruses. Therefore, rather than activating software, users inadvertently infect their computers. Criminals use third party download sources to proliferate malware. They achieve this by describing malicious executables as legitimate. In this way, criminals often trick users into downloading and installing malware manually. In summary, the main reasons for computer infections are lack of knowledge of these threats and careless behavior.
How to avoid installation of malware?
Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay attention when browsing the internet and downloading/installing/updating software. Think twice before opening email attachments. Files that seem irrelevant and those received from suspicious/unrecognizable emails should never be opened. You are also advised to download apps from official sources only, preferably using direct download links. Unofficial download/installation tools should never be used, since most include rogue apps. The same applies to software updates. Keep installed programs up-to-date, however, this should be achieved through implemented functions or tools provided by the official developers. Never attempt to crack software, since piracy is a cyber crime (you steal from the developers) and there is also high-risk of computer infection. Have a reputable anti-virus/anti-spyware suite installed and running at all times, since these tools often detect and remove malware before anything damage is done. 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.

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.
