A next generation operating system has to have it all figured out. With Windows 10, it\u2019s almost the case, although there is always room for improvement. For example, Windows Defender, a program that comes pre-installed with your operating system. This built-in feature allows protecting your computer from viruses and various other threats, such as malware and spyware. This feature is stored and run in the computer by another name that users rarely correlate with the service. It\u2019s called the \u201cMicrosoft Network Realtime Inspection Service\u201d process and is also known as NisSrv.exe.<\/p>\n

If you are looking at programs that are taking up space and deciding which one to get rid off, we strongly advise not to ever consider Nissrv.exe to be part of that list. However, if you are concerned about the power usage that is showing up high for nissrv.exe, you will find some workarounds in this article. So, what is nissrv.exe in Windows?<\/p>\n

If you are using Windows 7, you also have the program pre-installed as part of the Microsoft Security Essentials antivirus software<\/h2>\n

You should also be aware that these anti-malware products are your first line of defense if you have yet to install a protective antivirus. The possible downside of this feature is the large memory usage that it produces while scanning your system for possible infection with malicious programs.<\/p>\n

Windows Defender is running in the background but automatically checks and scans the system files for malware and prevents attacks from viruses. Once you install an antivirus of your own, however, Windows Defender stops the active protecting part but still continues with the scans to make sure that your antivirus is updated and active at all times. This is what makes the Windows Defender use a lot of memory power. So, how to fix nissrv.exe high memory usage?<\/p>\n

First of all, you should be aware that there is no need to disable the service.<\/h2>\n

Microsoft Network Realtime Inspection Service is an essential part of the Microsoft’s anti-malware software that is built-in not without reason. Developers are interested in enhancing your protection with new features, and not making your computer vulnerable to new viruses. However, if you decide to install a new program that will be doing things that are of the same caliber, i.e. antivirus software, then Windows Defender will gladly step aside and let the new antivirus take the lead, meaning that the process will automatically disable itself. A great alternative is the Auslogics Anti-Malware<\/a> tool that will also conduct scheduled scans and checks of your system but will definitely use up less memory than its built-in counterpart.<\/p>\n

\"Scan<\/p>\n

The second important point we want to make in this article is…<\/h2>\n

… that if you have any doubts that a virus is using the name of Windows Defender or nissrv.exe as a break-in technique – then you can check it quite easily. This fear definitely has some ground beneath it, as viruses and malware often have names that are trying to mimic important programs on your computer so that the user is confused and does not delete them. However, there are steps you can take to make sure that you are not being hoodwinked:<\/p>\n
