What is MSASCuiL.exe?

Msascuil.exe or MSASCuiL.exe is a safe executable file developed by Microsoft Corporation. The name of MSASCuiL stands for Microsoft antivirus security center user interface logo. This was first released in Redstone 1 Update, 2016 which runs at startup on Windows 8, Windows 10 and others. This file functions to display the icon known as Windows Defender Center for the Windows antivirus software.

This legitimate file/process is a part of Microsoft Windows 10 that can be found in the “C:Program FilesWindows Defender” folder. It is also known as part of the Windows Defender user interface. Unfortunately, most of these files and processes of msascuil can be used by cyber criminals to disguise malicious processes and programs.

Why Does Msascuil Contain Virus or Malware?

Msascuil is associated with Windows Defender as an anti-virus suite created by Microsoft. However, it is a legitimate file/process which can be trusted. But, cyber criminals really use this name of Msascuil to camouflage malicious software and the processes in Task Manager.

They basically create minor changes to names which cannot be noticed without careful inspection. Moreover, malicious files with similar names are placed in other folders and not designated for the origin of legitimate versions. Then, a malicious process is placed outside of the “C:Program FilesWindows Defender” folder.

Then, if the msascuil.exe is used to hide a malicious file, it surely should be removed immediately. Possibly, it can be a trojan which may lead to serious problems which relates to privacy, financial loss, browsing safety, additional infections and more. The list of camouflage malicious apps includes a cryptocurrency miner named COINMINER or CoinMiner.

Well, before you do any action, of course we recommend you to run a scan with the installed anti-virus and check if it detects any threats relating to this file. Because of the mistakes in the database, some anti-virus may detect legitimate files as threats and instigate removal of harmless system files.

When the security software detects legitimate files as threats, it is really called as a false positive result. But, those mistakes are basically fixed faster.
