Megalodon virus removal guide
What is Megalodon?
Megalodon is a high-risk trojan that behaves like a Remote Access Tool (RAT) and a key-logger. Developers typically proliferate this malware using email spam campaigns. They send thousands of emails encouraging users to open attached files (most of which are Microsoft Excel documents). They present these attachments as invoices, bills, or other payment-related documents. In any case, opening the attachment leads to infiltration of Megalodon.
As mentioned above, Megalodon provides cyber criminals with remote access. In this way, they can manipulate systems remotely and perform malicious actions. The presence of these infections can lead to a number of issues, since cyber criminals can download and inject additional malware. For example, they might infect computers with ransomware and cryptominers. Most ransomware-type infections compromise stored data (usually, by encryption) and make ransom demands in exchange for recovery of users' files. The cost usually fluctuates between $500 and $1500 in Bitcoins, Monero, DASH, Ethereum, or another cryptocurrency. Note that cyber criminals often ignore victims, once payments are submitted. Therefore, no matter what the cost, it should never be paid, since victims are commonly scammed. Mining trojans misuse infiltrated system resources to mine cryptocurrency without users' consent. The mining process can take up to 100% of system resources. Therefore, the system becomes unstable (it is likely to crash) and virtually unusable (it barely responds). In addition, fully loaded hardware generates excessive heat and, in certain circumstances (bad cooling systems, high room temperatures, etc.), the components might overheat and be permanently damaged. Another Megalodon feature is key logging. This virus records users' keystrokes. Furthermore, viruses that have this functionality typically record browser credentials (saved logins/passwords, cookies, browsing history, etc.). Therefore, cyber criminals can gain access to personal accounts on social networks, banks, email service providers, and so on. These people aim to generate as much revenue as possible and often misuse stolen accounts through online purchases, money transfers, borrowing money from victims' contacts, and so on. Therefore, the presence of Megalodon can lead to serious privacy issues, significant financial/data loss and software/hardware damage.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
The internet is full of trojan-type viruses distributed using spam email campaigns. The list of examples includes (but is not limited to) More_eggs, Brushaloader, Adwind, TrickBot, FormBook, and Emotet. The developers are different and, thus, the behavior of these infections also differs - some gather information, others inject additional malware, etc. Essentially, however, all of these viruses pose a significant threat to your privacy and computer safety. Therefore, eliminating trojans such as Megalodon is paramount.
How did Megalodon infiltrate my computer?
Developers proliferate Megalodon using spam email campaigns. This is very common to trojans of this type. As mentioned, they send hundreds of thousands of emails to regular users encouraging them to open the attached Microsoft Office documents. Once opened, these files exploit the Microsoft Office CVE-2017-11882 vulnerability to inject Megalodon into the system. Bear in mind, however, that the documents must be opened first so that the malware can infiltrate the system. Thus, lack of knowledge of these threats and careless behavior are the main reasons for computer infections.
How to avoid installation of malware?
To prevent this situation, be very cautious when browsing the internet. Carefully analyze each email attachment received. If you receive a file/link that is irrelevant or the sender seem suspicious/unrecognizable, do not open anything. These emails should be deleted immediately. Furthermore, use the latest version of Microsoft Office, since most trojans are proliferated using documents that exploit this software suite's vulnerabilities. The newest version has most the bugs fixed, and is thus safer. Furthermore, 2010 and newer versions are implemented with "Protected View" mode, which prevents malicious documents from automatically executing macro commands designed to download and install malware. Have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate malware before the system is harmed. The key to computer safety is caution. 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.

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 Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
