Sakula virus removal guide
What is Sakula?
Sakula is software categorized as a remote access trojan (RAT). Generally, programs of this type are used by cyber criminals to control infected computers remotely and perform tasks that enable them to generate revenue in various ways. Typically, victims are unaware that the Sakula RAT is installed on their systems. RATs can cause serious problems and should be uninstalled immediately.
Cyber criminals who use Sakula target government, healthcare, technology, and other sectors of this type. One feature of Sakula is that it can be used to download and execute malicious executables, thereby infecting computers with ransomware, trojans, and so on. Ransomware locks files stored on the computer and keeps them inaccessible unless a ransom is paid. Typically, these programs cause financial and data loss. Cyber criminals can use Sakula to send shell commands over HTTP, thus allowing them to perform various tasks on the infected computer. For example, to launch/execute applications installed on the operating system. It can also be used to create remote shells - programs that execute shell commands as another user and on other computers connected to the network. This RAT can update the Command-and-Control (C2C) server used by cyber criminals to maintain communication with the infected system within a target network. It can also receive malware status and send this information to the C2C server. It can also uninstall malware or put a RAT into 'sleep mode' so that the RAT cannot be detected and does not run any process on the system. These are the main features and reasons why Sakula should be uninstalled immediately.

More examples of RATs are FlawedAmmyy, Orcus, NetSupport Manager, and Rescoms. No matter who they target, cyber criminals use programs of this type to generate as much revenue as possible. They steal credentials (logins, passwords) of various accounts, infect computers with high-risk malware, hijack webcams, microphones, and so on. In summary, people or companies who are targeted by these programs can experience serious problems.

How to avoid installation of malware?
Avoid opening attachments or website links presented in irrelevant emails that are received from unknown, suspicious addresses. Download all software using direct links and trusted, official websites. Do not use third party downloaders, installers, unofficial websites, or other channels/tools of this kind. Update installed software through tools or implemented functions designed by official software developers. If software is not free, it should be activated properly. Do not use 'cracking' tools to bypass paid software activation, since this is illegal and they are often fake. Have a reputable anti-virus or anti-spyware suite installed and periodically scan the computer with it. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

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 Combo Cleaner Antivirus for Windows.
