Trojan:Win32/Meredrop
Written by Tomas Meskauskas on (updated)
What is Trojan:Win32/Meredrop?
"Trojan:Win32/Meredrop" is the codename of a high-risk trojan. Although there are a number of "Trojan:Win32/Meredrop" variants, all have identical behavior - the infiltrate other malware into the system. There is typically just one major difference: after infecting the system, "Trojan:Win32/Meredrop" either terminates or self-deletes.
As mentioned above, "Trojan:Win32/Meredrop" is designed to inject other viruses into the system. It places the malicious files in the "Windows" or "Windows\System32" folder and then immediately executes the downloaded malware and shuts down/self-deletes.
Be aware that trojans like "Trojan:Win32/Meredrop" might distribute extremely high-risk viruses, such as ransomware. This type of malware locks the system and/or stored files in order to blackmail victims - they are encouraged to pay hundreds or even thousands of dollars to restore the system/files to their normal state.
In addition, trojans can distribute viruses that collect various sensitive information (e.g., keystrokes, web browsing activity, saved logins/passwords, and so on). Once recorded, this information is sent to a remote server controlled by malware developers.
These people might gain access to personal accounts (e.g., social networks, PayPal, bank, etc.) Their only aim is to generate as much revenue as possible. Therefore, the presence of data-tracking malware can lead to serious privacy issues and significant financial loss (stolen accounts might be misused for online purchases, money transfers, and so on).
Another popular type of virus is the cryptocurrency miner. These tools misuse system resources to mine Bitcoins, Monero, and other cryptocurrencies. The process might take up to 100% of the resources, thus making the computer unstable and virtually unusable (it barely responds and can crash).
In addition, mining functions generates excessive heat. Therefore, within certain circumstances (e.g., bad cooling systems, high room temperatures, etc.) computer components can overheat. In summary, "Trojan:Win32/Meredrop" poses a significant threat to your computer.
Therefore, if you suspect this trojan's presence, you are strongly advised to scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are dozens of trojan-type viruses that share similarities. Some are more advanced than "Trojan:Win32/Meredrop" - as well as proliferating other viruses, they gather sensitive data. In some cases, however, trojans are simple - they merely collect information.

How did Trojan:Win32/Meredrop infiltrate my computer?
Cyber criminals proliferate trojans in various ways, however, in most cases, these viruses are distributed using spam email campaigns and fake software downloads/updates. Spam emails are delivered with malicious attachments (in most cases, Microsoft Office documents) that, once opened, download and install malware.
Fake downloads/updates, on the other hand, present malicious executables as legitimate software. Therefore, users are often tricked into downloading and installing viruses. Essentially the main reasons for computer infections are poor knowledge 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 close attention when browsing the Internet and downloading/installing software.
Carefully analyze each email attachment received - you should never open files that seem irrelevant or have been received from suspicious/unrecognizable email address. It is also very important to download your programs from official sources only, using direct download links. As mentioned, third party download sources might present malicious files as legitimate software.
The same applies to app updates. Keep installed applications updated, however, use only implemented functions or tools provided by the official developer.
Have a legitimate anti-virus/anti-spyware suite installed and running. If you believe that your computer is already infected with "Trojan:Win32/Meredrop", 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 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, 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.
Outstanding!
