[QUOTE="Local Host, post: 812778"] The same old topic, that has spammed this community with a new discussion about it at least once a week, if people used the search feature would spare us of the frustration to say the same thing over and over. Fact is Windows Defender performance has improved with each Windows 10 build, but it still lags behind third party solutions. Comparing Windows Defender to Kaspersky Free on laptops and desktops over the course of months now, and it's easily noticeable. But it all goes down to the usage you're going to make of the PC, in some cases Windows Defender will be barely noticeable (but never superior to third parties in any way, I say equal at max). However if you using the computer for games, work, etc. You'll notice the performance hit from Windows Defender with ease. Adding to this the fact Windows Defender still has exclusions bugs (which fail to comply with exclusion rules, and keeps nagging you over false positives on top of deleting your files), that another problem with Windows Defender false positives (this constant frustration where I constantly had to send my code for review to Microsoft so they could whitelist the files, else I wouldn't be able to implement and use them across companies). Any unknown unsign file will trigger Windows Defender, for someone like me who writes software, scripts, etc for work and even personal usage, it gets in the way a lot (compared to Kaspersky Free which never nagged me once on any machine). As a bonus, when compiling code with Visual Studio, Windows Defender adds a delay of minutes compared to Kaspersky Free seconds on the same machine. I'll be looking forward to what the new Windows 10 Build has to offer, however I don't expect miracles. [/QUOTE]
