Trojan.Mdropper Removal

I wrote this article to help you remove Trojan.Mdropper. This Trojan.Mdropper removal guide works for all Windows versions.

As its name reveals, Trojan.Mdropper is a Trojan horse which drops malicious files on the targeted machines. The malignant program drops setup files in .exe, .dll and other formats. Once aboard the computer’s HDD, the setup wizard triggers the install of the contained software. Trojan.Mdropper carries different types of infections, including rootkits, exploit kits, hijackers, potentially unwanted programs, adware, worms and ransomware. If you do not act timely, the clandestine program could inflict irreparable damages to your system, leak your personal and financial details, unleash a virus which will lock your private files and turn your machine into a pawn of cyber crimes.

All these statements are not exaggerations. The events listed above could occur. You could be faced with one or more of the threats. We will explain how the chain of events unfolds. The first step is to infect a computer with the Trojan. Trojan.Mdropper uses an established propagation vector to gain entry into users’ machines. The predominant method is spam emails. The Trojan has been spotted in campaigns where it traveled hidden behind .doc and .xls files. Research into the distribution pattern revealed that Trojan.Mdropper exploits vulnerabilities in Microsoft Office. The payload of the rogue program is transferred through a malicious script, hidden inside the document.

A spam campaign confirmed to be transporting Trojan.Mdropper attaches a document with a list of company staff and their phone numbers. The infected file is in .xls format. The bogus messages can vary in topic. Examples for spam messages include notifications about receipts, invoices, bills, fines, subpoenas and other important documentation. The person behind the letter will try to convince you that the message is genuine. He can write on behalf of a legitimate organization, like the local police department, the national post, a courier firm, a bank, a government branch, a social network, etc. To check whether a letter from your in-box is reliable, proof the listed contacts. The email address is the best indication.

Trojan.Mdropper performs a few malicious tasks. The main purpose of the nefarious program is to spread infections. The Trojan will turn your computer into a botnet. It will launch remote attacks on other devices. Trojan.Mdropper uses TCP Port 80 to communicate to a remote location. The remote attacks target machines from all parts of the world. The Trojan functions as a collaboration tool. The developers of the clandestine program work with other cyber criminals. They assist other hackers in distributing malware. Trojan.Mdropper has been involved in spreading worms, ransomware, exploit kits, rootkits, hijackers, adware, potentially unwanted programs and other types of infections.

Having your computer become a part of a botnet is more dangerous for you than it seems. While the conducted attacks will not target your machine, you will be involved in an illegal activity. The legal authorities of your country can trace the attacks to your device. Cyber laws are different in separate countries. In the worst case scenario, you will be charged with negligence. The fine for mishandling your computer can be considerable. At the very least, you will be asked to have the Trojan removed. Taking timely actions can spare you the legal charges and court hearings.

Finally, we have to address the damage Trojan.Mdropper can inflict on your own device. The rogue program uses up a lot of CPU to conduct its malicious tasks. Your computer will become slow and unable to process your requests. It will often stall, freeze, crash and return error notifications. Apart from the inconveniences, there is a grave security threat.

Trojan.Mdropper has the ability to collect information from the infected device. The sinister program will access your system’s specifications, like the type and build of your OS, the browsing clients you have installed on your system and their versions. The Trojan can also gather personally identifiable information (PII), like your IP address, geographic location, area code, email account, telephone number, physical registration, user names, passwords and other sensitive details. The hackers will try to access your online accounts and steal from them.
