Category: Trojan Damage: Severe Data added: September 29, 2021

MassLogger virus is a malicious program that is part of trojan viruses. The purpose of MassLogger virus is to steal users' data. The spread of this trojan often occurs through spam emails and fake updates.

What is MassLogger virus?

MassLogger virus hijacks web browsers, where it changes the display of information. The logins and passwords entered are stolen and sent to the fraudsters' remote server. By stealing logins and passwords, cybercriminals can quickly take over users' electronic accounts and transfer money to their wallets.

Cybercriminals use this feature to make users pay a ransom. Additionally, the trojan steals saved passwords, autocomplete, and other types of information. MassLogger virus also contributes to recording data related to browsing the Internet (history, cookies, and more) and PC system data.

This malware should be destroyed because MassLogger virus can mask itself perfectly in the PC system.

MassLogger virus symptoms

MassLogger virus can masquerade as a safe process and is difficult to find. However, the PC system begins to show itself with characteristic common symptoms, such as:

  • The processor consumes more of the computer's system resources.
  • The PC often hangs and crashes.
  • Browsers are flooded with malicious pop-ups.
  • Random windows start working on their own, with no action on the user's part.
  • Pages in the browser redirect the user to rogue sites.

How did MassLogger virus get on my PC?

MassLogger virus is spread via spam and fake updates. Spam is a variety of malicious attachments (PDF files, MS Office documents, and more). The user executes prescribed scripts by going to such extensions, and they secretly download and install the trojan.

Fake update programs start infecting the system by applying bugs and flaws in outdated software.

The main methods for viruses to appear:

  • A program with a virus is downloaded and installed on the PC (free programs often come bundled with MassLogger virus).
  • An infected email is opened.
  • The user clicked on a pop-up ad.
  • Peer-to-peer networks.

The trojan program starts a chain reaction, additionally installing other viruses.

MassLogger virus: legitimate or fake?

When a user notices a MassLogger virus file, he can check whether it is legitimate or fake in two ways.

  • File location. The standard file is located in the C:\Windows\System32 folder. All other files with MassLogger virus in their title are placed in different folders but not in the C:Windows\System32 folder.
  • Task Manager. First, start Task Manager - go to 'Processes' and look for MassLogger virus.exe - right-click on it to remove it - if Windows shows a warning message, then MassLogger virus.exe is a good process and doesn't need to be removed. Otherwise, when a warning appears, the MassLogger virus.exe process is fake.
