dnstehachapi.exe is an executable file that can be seen within Task Manager. Unfortunately, but seeing it is not a good sign because it's one of the malicious files that are run by DNS Keeper virus. In most of the cases, it runs alongside dnsembreeville.exe file, which also belongs to the aforementioned program. However, we can assume that each of them has different responsibilities.
dnstehachapi.exe is considered to be a malicious file. Nevertheless, it can hardly affect your computer and its operating system on its own. However, it may slightly influence PC's performance, so it's better to terminate it ASAP.
As we have already mentioned, dnstehachapi.exe is not run by itself and cannot be considered as a plug-in or add-on on its own. However, if we take into consideration this executable along with dnsembreeville.exe file and DNS Keeper add-on, we have a full package of software that can successfully operate on a computer's operating system. dnstehachapi.exe is typically installed on Windows Task Manager and Windows startup so that it could execute itself and load DNS Keeper application once a contaminated system is booted.
If you have noticed dnstehachapi.exe file running in the background of the system, then in order to see whether we are speaking about a malicious file belonging to DNS Keeper adware, open Google Chrome, Mozilla Firefox, Internet Explorer or any other web browser and carefully analyze how does it operate. If you notice at least one pop-up advertisement labeled as “Ads by DNS Keeper”, then there is no doubt that you have run into adware. We have already described it in our blog. However, if you haven't heard about it yet, then we will warn you that it is set to display sponsored advertisements that are linked to predetermined destination websites. Unfortunately, sponsored websites that it may expose you to may not be safe to visit, so it's better to stay away from all DNS Keeper ads.
On top of that, DNS Keeper is accused of spying on the users. It uses tracking cookies and collects personally non-identifiable information (IP address, PC's location, URLs visited, data entered in certain websites, clicks, and so on). However, it may use such information not only for improving the service. It may also be sold to affiliate parties that may use it for whatever purposes they want.
Last, but not least, it's important to note that dnstehachapi.exe file can show up on your computer as if out of nowhere. Usually, the software that runs it spreads bundled with free software, so people who select “quick”, “express” or “typical” installation options when installing free programs automatically give permission for DNS Keeper and all its bundle end up on the system. All in all, you should better not ignore ads and redirects by this program because there is no chance of knowing what it is set to promote. If you have just noticed dnstehachapi.exe file running within Task Manager, we strongly recommend you to run Reimage Reimage Cleaner , SpyHunter 5Combo Cleaner or Malwarebytes and remove all suspicious programs that have quite unfairly entered your computer.
