Is Windows Defender Antivirus good enough? Should I stick with it or should I grab another AV? Any thoughts?

I don't think you're gonna notice any performance issue while gaming with Window Defender. On my potato laptop newer games run poorly no matter what the antivirus is. I haven't used any resource hungry AVs though. I have WD set at High setting via Configure Defender and also manually set it to check for update every hour. So, it even updates while I play an online game like "Tom Clancy's Rainbow Six Siege" which won't be the case for her but still I face no lag/fps drop whatsoever. Besides, your gf's laptop is not potato like mine so she's gonna be fine with Windows Defender. Don't worry too much.

This can depend on the game and settings. The higher resolution, game details and other enhancements the more problems with game performance.

That's correct of course. But all the gamers I know don't bother installing any other AV and they never faced any problem so WD is fine I think specially now because it has got much better now than it was 2-3 years ago.

Thank you for your reply. actually I have only emsisoft and McAfee subscription left so what shall I do please tell me an effective protection without much system impact.
Open the separate thread with software/hardware specification related to your computer. Effective protection will depend on many factors, including your knowledge about security, safe habits, computer purpose (banking, gaming, productivity, etc.). You can also ask Evjl's Rain or another MT member who uses Windows 8.1.

You cannot use Windows Defender if you are on an AMD CPU because all of the optimizations were designed with Intel... Microsoft should be sued for this but anyway. Slap Kaspersky Security Cloud Free and your PC will actually be faster and more protected than with WD.

This is news to me. Do you know where you found this out, I’d like to read about it?
Just my bad phrasing. Of course you can use Windows Defender Antivirus but it won't be as well optimized.

Based on WD, make settings using all kinds of fine adjustment software. Every time something happens, GF will ask you for help. Eventually, you will become intimate and the relationship will evolve into a new stage.
;)

I will comment from my experience. Many people who buy pc to play games don't like the details of security software. You could say you're not interested. I think the first priority of the choice is that there is little post-installation adjustment. If I were you, I would choose WD.

I want to ask one question I have an laptop with windows 8.1 pro and recently got the security intelligence update so shall I consider other after market AV or this one is effective.
I don't recommend using Windows Defender on windows 8.1 because it's not as strong as WD on windows 10 but it's more stable than the one on windows 10 and somehow consumes less resource
Windows 8.1 has Windows Smartscreen which is the best feature to protect you from malwares => Windows 8-10 users have significantly fewer infetions than Windows 7 users thanks to Smartscreen (Windows Defender also benefits from smartscreen)
You should use another AV such as Kaspersky, Emsisoft,...

However, every AV has some impact on your computer so you have to tweak your AV for better performance. I would not use any AV in its default settings unless they don't allow or they don't have options to improve performance

if you use Kaspersky security cloud free, you can visit my Configure thread to read my Kaspersky tweaks for maximum performance as a reference

Update: Hey guys! I'm currently installing ESET NOD32! Choosing it is a no brainer, simply because of its game mode and lightness. I'll post my gf's laptop config later but here is the current setup;
AV: ESET NOD32 Antivirus
Firewall: Windows Firewall
On-demand Scanners: EEK, ZAM and MBAM
Additional Security Software: NVT SysHardener and NVT OSArmor
Browser Plugin: AdGuard Extension, BitDefender TrafiicLight and HTTPS Everywhere


Thank you very much guys for helping me! :)

This article says the opposite (in some way). It says that if you use some Intel chips, then this can improve the performance when you also use Windows Defender. Simply, WD can make use of this Intel technology to minimize the impact of security on performance. (y)
This, of course, does not improve the performance when AMD hardware is used, when you have WD or another AV.
