Win32:MdeClass – More Information

Win32:MdeClass is a Trojan application. Other viruses from this type that recently appeared include the VirTool and Ursnif Trojans.

But how does such a threat end up on your computer? One very effective strategy is to include the Trojan components in a program that victims downloaded from shady websites. Such programs typically end up being:

Another method of infection used by these Trojans is to get sent to you via e-mail. In these e-mails the Trojan file may pretend to be a legitimate document, like a PDF or Microsoft Office file. These files may contain the so-called malicious macros that cause an infection when you open the document and click on “Enable” to see its content, which triggers the virus. If sent by e-mail, these documents often seem like they are:

  • Invoices.
  • Flight tickets.
  • Document from a bank.
  • Work-related file.
  • Receipt for a purchase you don’t remember making.

  • %Local%
  • %Roaming%
  • %LocalLow%
  • %Temp%
  • %AppData%

Once the files are dropped, this malware may run commands in Windows Shell that may make its virus files to run as administrator. This makes them the ones in power over the following activities that this Trojan may do to your computer and information in it:

  • Steal and delete files and financial information.
  • Gather information from your browser.
  • See what you type on your keyboard by using keylogging software.
  • Steal passwords and logins.
