Orcus virus removal guide
What is Orcus?
Orcus is a Remote Access Trojan (RAT). Programs of this type are used to remotely access or control computers. Generally, these tools can be used by anyone legitimately, however, in many cases, cyber criminals use them for malicious purposes. They often trick people into installing these programs and then use them to steal various information to generate revenue.
The Orcus program can be downloaded from its website and is promoted as having features similar to TeamViewer and other software. In fact, Orcus includes some illegal features such as the ability to disable the webcam activity light, retrieve passwords from well-known applications, and retrieve browser cookies. It is also capable of using the microphone to record sound (any input), performing key logging (logging keystrokes), and so on. These features are not included in the basic version of Orcus, however, they can be purchased for $40. Note that this RAT is promoted on a hacking forum on which people can purchase and sell malicious programs, exploits, hacks, and other material of this kind. Research shows that some cyber criminals use spam campaigns (emails) to trick people into installing this particular tool. They send emails that are presented as messages from "Lathe and CNC Machines" as invoices. These emails include attachments that, once opened, download and install Orcus. Spam campaigns are one of the most common ways to proliferate computer infections, or legitimate tools such as RATs, which can then be used in malicious ways. If installed, this tool can be used to steal passwords, logins of accounts, and other, sensitive, confidential details. Some of the plugins are capable of downloading files, including computer infections such as ransomware. Therefore, being tricked into installing this tool might result in financial loss, issues with privacy, computer infections, and other serious problems. If installed, this tool might be disguised as another application running in the system background. In our example (see screenshot above), it runs as a "PK Holdings.exe" process in Task Manager.

There are many remote access trojans (RATs) on the internet. Some examples are Agent Tesla, Imminent Monitor, H-Worm, and CrimsonRAT. These tools are legitimate, however, they can be used by cyber criminals with malicious intent. If a RAT is present on your system and you did not intentionally install it, remove it immediately.

How to avoid installation of malware?
Irrelevant emails should be ignored, especially if they are received from unknown, suspicious addresses, or contain web links or attached files. Software should be downloaded using official websites and direct links (not the other tools mentioned above). Software updates should be made using official tools or implemented functions that are provided by official software developers. Paid software should not be activated using third party tools, since this is a cyber crime. Furthermore, cyber criminals often employ them to proliferate computer infections. It is also important to have a reputable anti-spyware or anti-virus suite installed and keep it enabled at all times. Without these programs, computers become vulnerable to computer infections. 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:

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.
