Trojan.generickd is a email-spamming Trojan Horse infection that is delivered to the computers of its victims disguised as a PDF file. In truth, the Trojan.generickd is actually an executable that, once opened, starts to make system changes and send out spam emails.

1 2

The malicious Trojan.generickd executable file is typically distributed with the help of a ZIP archive that’s been uploaded to various file-sharign sites and can be downloaded from them. The ZIP archive that contains the malicious .exe is usually named DHL_Report_[random numbers]. Once you extract the contents of the ZIP archive, the harmful executable would appear on your system. However, it would typically be disguised as a PDF file in order to mislead you about its true nature. Once you attempt to open the fake PDF file, you’d get an error message that tells you the file cannot be opened. In reality, this error message means that the Trojan.generickd threat has become active and is now operating within your system. However, you will likely not notice any immediate symptoms, so if you aren’t aware of the nature of the fake PDF file, you may not realize that your computer has been infected for quite some time.

What is Trojan.generickd

Trojan.generickd is a malicious Windows virus known for making changes in the system Registry and sending out spam emails from within the infected computer. Trojan.generickd is mainly distributed as an executable disguised as a PDF file that’s included in a ZIP archive.

If you fail to realize that the PDF contained in the DHL_Report_[random numbers] ZIP archive is actually a malicious executable, and you end up opening that file, the Trojan.generickd virus would become active and would immediately start injecting malware code into various important system processes, including the explorer.exe process. The malware would also contact its servers (provided that your computer is connected to the Internet at the moment), which are primarily located in Japan, the US, and the UK. From its servers, it would download various helper files in the user folder on the computer. Those files, too, would be disguised as PDFs so that you’d be less likely to notice them as something harmful. One common system location where you may find files downloaded by this virus is the Temp folder, which is why deleting everything in that folder is an important step when trying to remove the Trojan.

Additionally, the Trojan.generickd would also make changes in various types of settings, including the System Registry, the LAN settings, and the browser settings. Because of those changes, it is likely that you’d notice issues with your Internet connection and the behavior of your browsers. Your Internet may become slower, you may start getting strange and unusual online notifications and pop-ups, and you may also start getting redirected to questionable websites that you didn’t try to visit. If you start noticing any such strange browser behavior, make sure to avoid any interaction with questionable content that you may get exposed to as this may lead to further issues.

According to security researchers, the main end goal of the Trojan.generickd threat is to use your system as a platform for sending out spam messages. Apparently, one of the files created by the virus – the 25.tmp file – tries to connect to SMTP servers and, if successful, it starts sending out spam email messages to a preset list of contacts. That list of contacts is also downloaded from the Trojan’s servers.

Even though there currently isn’t information about this Trojan trying to harm the computer that it infects, or the data located there, it’s still highly important to ensure that this threat gets removed ASAP. Despite it being used primarily as a spam-distributing tool, the fact that it can freely perform actions in the infected system without the knowledge or the permission of the user means that it can easily be repurposed to execute other, more harmful tasks. For this reason, if you think or know that the Trojan.generickd virus is currently in your PC, it’s strongly recommended that you have a look at the following removal guide and complete the instructions we’ve shown there in order to ensure that the Trojan threat gets fully eliminated from your PC.

    Type msconfig in the search field and hit enter. A window will pop-up:



    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

    • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)


    If there are suspicious IPs below “Localhost” – write to us in the comments.



    Type Regedit in the windows search field and press Enter.

    Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

    • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
      HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
      HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
