ronb wroteWell, I guess I just respectfully differ. I have been using Windows Defender since Dec 2012, before that I used Avast for many years. Windows Defender works well and is very quiet - not always reminding you it has updated, not alerting you to possible dangers which with Avast were usually false alarms. My Internet usage is moderately risky. By that I mean while I am very cautios about clicking on sus links, I do download and install lots of software, download movies, music etc.
I have read many reviews of Windows Defender, and seen Microsoft's cautious or ambivalent endorsements - and my conclusion is that it does work, and Microsoft's caution is probably trying to head off potential legal actions.
Probably the automatic Windows updates are doing more of the work than Defender itself - so leave auto updates on and make sure your computer stays on at least some nights.
So, in the end, everyone has to choose for themselves - good luck.
False positives crop up in many AV software - again, some more than others.
I respectfully differ from you. Windows Defender (MSE), is Microsoft rubbish. Microsoft's "cautious or ambivalent endorsements" are not "ambivalent" at all.
They admit that it ain't enough. Install a 3rd Party AV.
As for automatic windows updates - they're a mixed bag too. There was a recent one which screwed up many computers.
Personally, I [B]never[/B] activate automatic Windows updates, just in case. Sure, let Microsoft [B]tell[/B] me what updates are available, but never download the whole lot automatically.
Wait a while in case some update was a dud.
If you've been relying on Windows Defender and haven't had a "problem" since 2012, you're lucky.
Microsoft has had a history of confusing naming for some of its software. Remember Outlook and Outlook Express? Completely different beasts.
Microsoft has an "offline" Windows Defender, which is nothing like the BS one that comes with the OS. You have to download it and burn it to a bootable disk.
Boot from the disk, get the latest definitions and scan [B]before[/B] Windows starts.
Of course, there are many similar (even better), bootable solutions available from other 3rd parties.
