What is SppExtComObjHook.dll?

The SppExtComObjHook.dll file is associated with various illegal software activation tools such as KMSPico, AutoKMS, Re-Loader, and KMSAuto. These tools active Microsoft Windows or Office products without requiring payment. Typically, anti-virus or anti-spyware suites detect the SppExtComObjHook.dll file as a threat when opening one of the aforementioned (or other) activation tools. Using these tools is illegal and they often infect computers with malware.

SppExtComObjHook.dll malware

Typically, activation tools such as KMSAuto, KMSPico, AutoKMS, and Re-Loader can be downloaded from various dubious websites, and some might be presented as "official". There are many cases whereby installed anti-virus or anti-spyware programs prevent people from opening downloaded executable files that supposedly install 'cracking' tools. As mentioned, security programs detect SppExtComObjHook.dll when one of these activation tools is opened. This alone indicates that tools of this type cannot be trusted. Cyber criminals use them to proliferate malicious programs - activation tools download and install malware rather than activating other software. This makes it convenient for criminals to trick people into causing installation of malware by encouraging them to disable their anti-virus or anti-spyware programs before launching an 'activator'. In doing so, people allow malware to be installed without detection. Unwanted download and installation of malware is not the only problem caused by these tools. They are often used to distribute cryptocurrency mining programs. These programs use computer resources and force computers to consume excessive power. Therefore, infected computers work slower and people receive higher electricity bills. Remember, software 'cracking' tools cause serious problems and using them is illegal.

KMSPico, AutoKMS, and Re-Loader are examples of just some activation tools - there are many more. Typically, these tools are created by different cyber criminals. Some might not proliferate malicious programs, however, it is illegal to use them anyway. To avoid computer infections, financial loss and other problems, we recommend that you activate all software properly.

How did SppExtComObjHook.dll infiltrate my computer?

The SppExtComObjHook.dll file infiltrates systems through KMSPico, AutoKMS, Re-Loader, KMSAuto or other activation tools. Alternatively, they can infiltrate through Windows installers that already have an activation tool implemented. In addition to software 'cracking' tools, cyber criminals choose other ways to proliferate malware. For example, spam email campaigns, trojans, untrustworthy software download sources and fake software updaters/updating tools. Using spam campaigns, they send emails that contain an attachment or website link. Typically, cyber criminals attach a Microsoft Office document, PDF document, archive file (ZIP, RAR), executable file (.exe) or JavaScript file. The main goal of these emails is to trick people into opening the files. If opened, the attachment installs a malicious program. A trojan is another malicious program that, if installed, causes chain infections. One of the purposes of trojans is to proliferate viruses. Cyber criminals proliferate malware through Peer-to-Peer networks (such as torrents, eMule and so on), freeware download websites, free file hosting sites, unofficial websites and other such tools. They attempt to trick people into downloading and opening malicious files that are disguised as legitimate. If they succeed, people end up downloading and installing computer infections. Fake (unofficial) software update tools cause computer infections by exploiting bugs/flaws of outdated software or by downloading (and installing) malware rather than the promised updates, fixes, etc.

How to avoid installation of malware?

Download, install and update software, and browse the web responsibly. It is not safe to open attachments (or web links) that are present in emails received from unknown, suspicious email addresses. If they seem irrelevant, they should be ignored and the contents should remain unopened. We recommend that you keep installed software updated, however, use implemented functions or tools that are provided by official developers only. The same applies to software activation. These tools are illegal and cannot be trusted. Furthermore, avoid downloading software from untrustworthy or unofficial sources. The best way to download is to using official web pages and direct download links. Additionally, have reputable anti-spyware or anti-virus software installed and keep it enabled at all times. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

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.

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 Spyhunter for Windows.
