The process mv61xx.sys is a component of the Marvell Thor Windows Driver from Marvell Semiconductor, Inc. Marvell supplies drive control chips for computers. The Windows Driver Model, also known as the Win/32 driver model is the framework for device drivers that replaced VxD. WDM drivers can be classified into three major types, the device function drivers, bus drivers, and filter drivers. The device function driver, or main driver, is written by the device vendor and could be either a class driver or a miniport driver. Class drivers provide interfaces between different levels of the WDM architecture and can be considered built-in framework drivers on which miniport and other class drivers can be built on. Miniport drivers are function drivers for audio, USB, SCSI, and network adapters. The bus driver services a bus controller, bridge, or adapter. The most common buses for which drivers are provided are FireWire, USP, PCI and SCSI. Filter drivers are optional drivers that value to or modify the behavior of a device and may be non-device drivers. The Microsoft Windows Driver Model unified driver models for the Windows 98 and Windows 2000 product lines by reducing the amount of code that need to be written and standardizing the requirements.

A process usually a part of an installed application such as Marvell Thor Windows Driver Module, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.

We have not received any complaint about this process having higher than normal impact on PC performance. If you have had bad experiences with it please let us know in a comment below and we will investigate it further.

The first thing you should do if mv61xx.sys. is causing errors on your computer is to run a Windows registry scan with Registry Reviver If you are still seeing errors after this you should uninstall the program that mv61xx.sys, belongs to, in this case Marvell Thor Windows Driver Module
