Windows Defender
 
Does Windows Defender have serious system impact? Will it slowdown my PC. I'm running Win 10 all updated, Intel Core2 Duo, 2.33 GHz and 8.00GB RAM. Thanks.

No.
Microsoft's programs included with Windows has always been low on system resources.

Thank you EldonW.

I have Windows 10 32-bit with 4 GB of RAM. My experience is that Windows Defender does slow down my PC a bit.

I have always found it better to remove Defender and replace it with a decent third party tool.
Defender has never been known as anything other than a "better than nothing" tool even by MS.

Not any more. ;)
Have a look at this comparison.

Unfortunately, the 36 false positives spoil the glory. :o

I've never heard that from any official source at Microsoft so it would be good to provide a source reference for such a disparaging comment.

Microsoft's stated intentions have always been to provide a much higher level of protection than you've stated. And that goes all the way back to their purchase of Giant anti-spyware in 2004:

I think that you're probably confused about the Microsoft products. The AV Comparatives report that @EldonW links to is for the current anti-virus product rather than the original anti-spyware product which this topic is about.

Windows Defender is the name used for at least three different products:
  1. The original Windows Defender from 2005 was only anti-spyware for Windows XP and later for Windows Vista and 7. From 2009, Microsoft Security Essentials (MSE or MSSE) provided anti-virus for Windows 7
  2. Windows Defender for Windows 8 was an anti-virus that used the same definition files as MSE.
  3. Windows Defender Antivirus for Windows 10 supercedes both MSE and Windows Defender for Windows 8.

The user is running Windows 10. Therefor this topic is not about the original anti-spyware product.

I use Defender, haven't used anything else for years and never noticed it causing any slowdowns. And on a PC with the specs that the OP has posted there shouldn't be any problem. In all honesty, I've never had an issue while using it with Win10.

Windows Defender comes on whenever I uninstall Avast to install a new version. There is noticeable slowdown in the system, which I don't feel when Avast is installed. Specially, when I open a folder with exe files, there is a lag.
