Agree with youI think Windows Defender is the only good virus protection on Windows 10. But it's a bit different in terms of performance. That's where people and I argue.
Let's start with the fact that Defender has different speeds depending on what hardware you use. Defender is very hard disk heavy and if you only have a 5400 RPM hard disk, then the system becomes noticeably slower. But if you have an SSD (which is obligatory nowadays!), you don't really notice anything.
In this video it is said that Defender slows down the computer "only" 7%. However, this is only true for his computer (it is very likely that he has an SSD in it) and not for all of them.
Second, you should never evaluate the performance of a program/operating system in a VM. This didn't falsify so much in this test, but it would probably turn out differently on a real PC (by a few percent).
Totally.You don't need a benchmark video to see WD slowing down your machine, all this could've been avoided if the MS devs cared to implement scan-on-execution...
But download malware files will not be scanned by Bitdefender. I definitely don't want them on my disk in freezing stage.You don't need a benchmark video to see WD slowing down your machine, all this could've been avoided if the MS devs cared to implement scan-on-execution...
+1I have set WD to exclude scanning UAC protected folders. I have treid lot third party AV's, but there is no AV with less impactst on this (on the low end) of low end CPU's.
So with my experience you need to tweak Windows Defender when running bottom end of low spec CPU's, but with a Pentium or higher you should be fine with WD as your security defense. IMO problems occur when adding third-party security. I agree that WD has it flaws, but with some simple tweaks (@Andy Ful configure defender, Documents Anti-Exploit, Hard Configurator) it is great protection with minimal system impact.
Interesting. I don't spend much of my time installing programs, so I didn't even take that into consideration. So if I am going to install something massive, where time is a factor, like MS Office for instance, then I should disable WD.Just upgraded 3 PCs with SSDs and cleanly installed Windows 10 => WD really slows down everything in all machines, more noticeably during installation of essential programs.
