Taskeng.exe Virus Removal Guide

Taskeng.exe is a legit Windows process that runs the Task Scheduler Engine program. Task Scheduler Engine is responsible for running automatically specified process at pre-defined times. Unfortunately, like other well-known Windows files like svchost.exe, taskeng.exe is also used as a disguise of malicious files created by cyber criminals. So a blank black box pop up that shows an error and appears randomly can be a sign of taskeng.exe virus infection as the natural behavior of the process doesn’t imply popping up of any windows on the desktop. A malware infection disguised as taskeng.exe Windows process can cause various security issues like data theft, disrupted PC and browser functioning and even additional malware attacks.

Taskeng.exe –Virus File vs. Safe Microsoft Windows Process?

The pop-up error associated with taskeng.exe process may be part of various malware infection scenarios. In most of the cases, the tasking.exe pop-up appears because of annoying adware or browser hijacker that has infected the PC. Some reports of infected users reveal that Conduit Search browser hijacker may cause the error. Such potentially unwanted software is usually ad-supported which can slow down the infected PC and violet browser performance. Furthermore, taskeng.exe virus is able to record keyboard and mouse inputs. Gathered information can be sent to a server controlled by hackers.

The taskeng.exe virus can serve cyber criminals as a backdoor access that allows them to drop additional malware on the computer. Once the virus is running on the system, it can ensure its sustainable presence on the infected host by modifying Windows Registry keys like Run and RunOnce and adding custom values.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

These keys control all apps that start automatically each time the Windows is switched on.
