There are other things that can trigger a scan (line some Defender engine updates) that may reset the schedule. In any case, I still would not worry about it - especially when no threats are found.

From what I saw until now, the updates are daily, but the scan is probably set by default once a week.
The default scan is weekly but updates will occur at just about any time. I have seen multiple in a single day, and I have seen where nothing comes in a day. It just depends on what is happening out there in the wild. If a new vulnerability or exploit is discovered, MS will push out the update as soon as it is ready, even if another update came out just hours earlier. This is all good, IMO.

I am guessing that that date caused Windows Defender to do some sort of extraordinary scanning that it would not have otherwise done.  By that I mean that it probably searched every little item in the computer

I think that is a decent guess, but I don't think that is it - but admittedly, I am working on a couple "guesses" too. I note 1999 is commonly used by BIOS makers as the default date (until the correct date and time is set in the BIOS Setup Menu). Note a totally inaccurate date and time is a common symptom of a weak/failing CMOS battery. The two primary functions of the CMOS battery is to (1) keep the "user changes" to the BIOS firmware default settings "alive" in the CMOS memory and (2) keep the motherboard's RTC (real time clock) "ticking" ("counting" to be more accurate) when the computer is turned off.

If the motherboard's CMOS battery has never been replaced on this older system, I would probably replace it. Typically they are CR2032 wafer or "coin" batteries, found at nearly every battery counter.

While I agree it "appears" Microsoft Defender (Windows Defender is its old name) did a deep scan, the screen shot says "Quick".

Also I just counted every file on my computer by opening an elevated cmd prompt, moving back to the root on the disk (cd .. until I got C:\> on the command line) on this system, and entering dir *.* /s. That lists every file and folder in that root directory and then the /s forces it to list every file in every subfolder on that drive too. In other words, every file on the disk. Even with a fast SSD, it took several minutes to list all the files on my boot drive.

And still I only(?) had 589,368 files on C drive. I did the same on my secondary drive and it only showed 13,485 files. That's 1/3 of the 1.5 million files you first displayed. Checking the other computers here, and all had fewer files than this, my primary computer.

Now why do I show ~600,000 on the disks but Defender only scanned 46,000? That's easy. Security programs, including Microsoft Defender know that only certain type of files are used by the bad guys. These typically are files that can be "run", otherwise known as "executables". This list is not all inclusive but gives you a pretty good idea of the most common file types used by bad guys to insert their malicious code.

By not scanning every single file on your disk, scans not only take up much less time, they also bog down our systems much less, and (especially for mechanical drives) result in much less wear and tear on the drives. Note since scans are "read" actions (not "write") the wear on SSDs is negligible.

I really hope this is true.
It is. EACH and EVERY file downloaded and saved on our systems ARE scanned on the way in by the real-time scanner. Every time a file is modified and saved to disk, it is scanned. Plus, when you call up any file, including one of those obscure file types, the real-time scanner looks for "suspicious" activity and will halt that activity if something fishy is detected.

Last but not least, regardless your primary scanner of choice, everyone should have a secondary scanner on hand for "on-demand" or supplemental scanning just to make sure we (users and ALWAYS weakest link in security) or our primary scanner didn't let something slip by. In other words, "for peace of mind" and I use and recommend Malwarebytes for that.

FTR, Malwarebytes has never, not once found anything malicious on any of my systems here going back to Windows 7 in 2009 with Microsoft Security Essentials (the W7 version of Windows Defender), through W8 and now with W10 and Microsoft Defender. That's a pretty good track record, if you ask me considering 2 of my computers are regularly used by guests, including several ("it can never happen to me") teenaged grandkids.

The only thing Malwarebytes has ever found on any of my systems are a couple "wanted" PUPs (potentially unwanted programs).

So keep your OS and your security programs current and don't be "click-happy" on unsolicited links, then chill. Odds of getting infected are very very slim.

Is it possible you can still be infected? Of course! It is possible Fort Knox might be robbed too. How? One of the guards opens the front door and invites the bad guys in. Or, a super-duper professional targets it specifically and manages to exploit some "unknown to everyone else" vulnerability.

The difference here is Fort Knox doesn't have backup copies of all the gold. But you, of course, have multiple current backup copies of all your data, including at least one copy maintained "off-site"! Right?

Even though many of them will never be in use again.
Then I would recommend you move them off to a couple back up drives. If they will never be used again, then don't need to be scanned over and over and over... and over again.

Well, this computer is 6 years old, but has nearly 20 years worth of data on it. I'm looking at a nearly 46,000 files taking 1m 21s.

While you are scanning 1.5 million files, it is still taking a long time. Is that a hard drive?

I agree with Corrine and you need to cleaning up, deleting duplicates, and moving some files.

If you have multiple drives, my advice is to set Windows to create a PF on each drive and let Windows manage all of them.
Why? Is this a laptop with the battery removed?

Looks like it scanned to day and is scheduled to scan next Sunday. But again, it is running all the time and updates happen much more often than that - often several times a day, depending on what is happening out in the wild. I just checked again and another since my last post was released. Just another reason to let the computer go to sleep.

Well, again, if you turn your computer off when done using it, that would be expected.

Are you saying you still have that yellow warning?

I don't think that the scan took place at all.

The computer was on, and I was working on it.
It is purposely designed to scan way way in the background so you don't notice it.

It is important to remember that these scan really are not necessary, except for peace of mind. This because Defender is constantly monitoring our systems 24/7/365, not just looking for malicious code being saved on our drives, but everything coming in and going out of our systems (emails, webpages, etc., and malicious behavior that might be going on in the computer's memory.

The fact of the matter is, these scans are redundant.

Go back to your Settings > Virus & threat protection page. It will show the last scan and type (I have mine set to quick). Then look down a bit to Virus & threat protection updates. Mine right now says last update was today at 8:49. am and that my "Security intelligence is up to date". If yours says the same (time might be different), then you are good to go.

Possible factor: I currently have "Always register Malware Bytes in the Windows Security Center" turned off.
Yes - this is what you want if you want both Malwarebytes and Microsoft Defender to run at the same time. I have the same setting set in my Malwarebytes control panel.

I always shut it down (not send it to sleep).

I created a new task for every Sunday and I will see what is going to happen tomorrow.
Well, just remember your computer has to be on (or at least in sleep mode) for the scan to happen. If you shut it down, you likely will see your yellow warning again. That is normal behavior.

Ever few days, Windows Defender gets that yellow warning triangle, that a scan is needed.
I'm not getting these. The only time I see a warning that a scan is needed is when the computer has been turned off for several days and a scan has not been performed recently. Most notably I see this on my notebook because I don't use it often.

Microsoft Defender (formally Windows Defender) is designed to run when the computer is not being used or when you go idle. If you always turn off your computer when done using it, that may be part of the problem (though technically, telling you a scan is needed is NOT a problem). I just let mine go to sleep.

You can look in Task Scheduler to see when it is scheduled to scan. If no task is scheduled, it just scans based on the time it last scanned. If you set a schedule, it will scan at that time - unless you power off then it will attempt to scan when you come back.

My advice is to scan, then just let your computer go to sleep. Much happens to our computers when we are away - good things. Windows updates, housekeeping tasks (indexing, defragging and more) and our security programs (not just Defender) scan.

If you want to change the scan times and frequency, see How To Set Your Own Scan Schedule For Windows Defender Antivirus and scroll down to "Schedule Updates With Task Scheduler" (don't ask me why it says "updates". I think he meant to say "Scan times").

For the record, I recommend once daily scans though weekly is probably sufficient since Microsoft Defender is already scanning everything in real-time anyway.

Hi Tony and welcome.

Sadly, all you said was you were having cursor problems but you didn't provide any description of the problems at all! And you told us nothing about the computer. So we have absolutely nothing to go on. :(

Is this a laptop with a trackpad or PC with a mouse? And what kind of problems? Freezing? Jumping around? Disappearing?

we acknowledge that it was not fully prepared to share the level of detail or accuracy you expected from us

ROTFL

"It" was not fully prepared? Haha! Shame on "it" for putting "itself" out there before "it" was properly prepared.

Sounds like the same marketing weenies who pushed the first iteration of Microsoft Edge out with W10, long before it was complete, ready or "fully prepared" didn't learn their lesson and pushed this checker out long before it was complete, ready or fully prepared too. So, as a consequence, they have to pull it back and regroup - and look like fools in the process - dragging the good folks on the development team down with them.

When will MS ever learn that, when it comes to publicity, their own marketing team is so often their own worst enemy? You would think, after shooting themselves in the foot so many times, that they would get tired of it. I guess I'm dreaming and that is just too much to ask. :(

Interesting. Hopefully, when the latest version is complete, it will give precise details why, if a computer is not W11 ready.
