i have a client running windows 8.1. on a touchscreen laptop. He set a full scan and it was running for 58 hours till he finally shut it off.
He also has malwarebytes and on a full scan it took 2 days to finish.
Quick scans take about a half hour.
Why does Windows Defender want to scan my PC so often? I have it scheduled to scan daily at about 2:30 AM. Sometimes after about 4 hours it says I need to scan.

I am trying to do a windows schedule scan, but when I set it I am getting this (see attached)
For some odd reason WD keeps telling me I need to do a scan (it's in orange in WD) even though I do a scan everyday via the Task Scheduler. After any kind of scan it resets itself (I don't need to scan, green in color). Some time period later it tells me a scan is needed.
Is there some option that controls how often WD tells you to do a scan?
This started happening about a week or so ago. I don't have anything running on my system that IMO is doing this.
It is advisable not to do a full scan for the moment. There was a problem in the latest definition update and in some cases after doing a full scan, if it completes, Windows Defender has been turned off.
Microsoft is aware of the problem and is working on it.
Every few days I get a message in the Action Center that says I need to update and Run Defender.
I have real time protection and everything else turn on, why doesn't it do this on it's own.
Also I don't see any options as there used to be about when to run scans i.e. time and how often etc.
As far as I can see it has never quarantined anything but when I manually run a scan it come up clean, not surprising I guess because I run Malwarebytes every day, and SuperAntiSpyware regularly, and I'm using Comodo firewall.
I did run a fake test virus and it caught it immediately so it seems to be working fine.
In Windows 7 I used to be able to right click on a file and one of my choices was to scan with Microsoft security essentials, but that's no longer in my right click menu.
How do I go about doing a manual scan on just one file using Microsoft's (I guess it's now Defender) Security Essentials in Windows 8?
So a a day ago I woke up, turned on my computer, and was surprised at how long it took to turn on. It took, like, 30 minutes to get to the desktop screen (I have Pokki so it goes to metro for a seconds and then automatically goes to the desktop).
It took its sweet time trying to load steam and I ended up cancelling the load. Nothing loaded except for Launchy, not even the Pokki start button. I was surprised so I turned it on again and it kept going slower each time; I shouldn't have kept restarting, but I was stupid.
Anyways, I left the house and when I got home I restarted it twice before I decided to just let everything load. I was able to close the Steam startup, something I'd been trying to do for some time, but the computer had booted so slowly and the computer had lagged so badly I'd not been able to. I couldn't even open the task manager because when I moved the mouse down to make the taskbar popup it would lag. When I right-clicked it would take a minute or two to open the box and when I clicked on "task manager" it wouldn't open because the program would time out. There would be a Microsoft error pop-up box when it timed out. When I would get it to open it would take a long ass time to load and it crashed a few times.
Anyways, I decided to just let it load, it took 2-3.5 hours to open everything. I opened Advanced System Care Ultimate and ran a virus check and then I went to sleep, when I woke up it said that the check (a full scan) had run for 8 hours and there were no problems according to the program.
Things were still kinda laggy, but the speed of the computer was the same it had been when it as first laggy. So, unusable laggy, but not as bad as it had gotten. Also, it said that Windows 8 hadn't been activated and when I tried to activate it Windows said it couldn't activate it at the time.
The message left (after being there the whole night), but things were still laggy (oh and this is not the first time I have installed Windows 8 so during the night I also left it to delete the old windows.old folders, it would say that it kept finding new items. So, even the deletion of things was sloowwww). I turned on Skype and even though the internet was connected it didn't connect. I turned on the troubleshooter, but it would time-out. I opened Google Chrome and it actually opened! When that happened Skype started to work and, even though things were still laggy, I thought things were getting better. I saw a video.
I left the house, but I left everything on as Advanced System Care Ultimate checked for malware (after having run the antivirus check the previous night). When I got home the internet didn't work, but the computer was almost as fast as it was before (its got 4 years, and it recently fell, but there hadn't been any problems until that day. ACTUALLY, I don't know if this started before or after it fell, it wasn't from a high place, but the loading screen had been lagging for some time).
I ran the troubleshooter and it worked this time, it said that the Diagnostics Policy wasn't working. So, the internet stopped working in the 8-9 hours I was gone. Pokki still hadn't loaded, I went to PC settings and I tried to change the Lock Screen for no reason and it didn't work. I tried changing the account picture and that didn't work either. I'm at a loss, not sure whats happening to my computer, but its almost as fast as it once was.
Today I've tried doing a Chkdsk scan on my primary drive. Through the console, I entered this line to start the process on a re-boot 'chkdsk /f /r c:'.
I afterwards left it to do it's work for the next 1 and half hours '6:40-8:10pm', during this time I went to check on the progress of the scan and what I saw was that it was only '10%' into completion, this confused me greatly as previous computers that I have owned would atleast be around 70, or 80% percent completed, so not knowing what to do, I did a cold-boot.
From what I can tell, no visible damage has afflicted said the drive I did the chkdsk scan process on, but I would still very much like to know why my scan is hanging.
I have this identical problem mentioned here : Scanning and repairing volume (?Volume...) on startup
I think it has something to do with my deleting the 'system reserved' 350mb partition when I reinstalled Windows 8. I don't want it showing in My Computer and when I go into Disk Management and give it a drive letter, this message goes away on boot. But, since I can't merge this very small partition with any other drive, I'm not sure how to not show this drive and not get the scanning message on boot up.
I have some questions regarding the new Chkdsk in Windows 8 (I'm using Windows 8.1 Pro 64bit).
note that Windows 8's Chkdsk has changed considerably since the previous Windows versions; so if you know about the Chkdsk in Windows 7 or previous Windows versions, this could not apply to the Chkdsk in Windows 8.
I also point out that I'm talking about the GUI version, accessible from the drive's properties Window.
My main questions are: when Chkdsk has finished scanning, and the results window appears, can I at once proceed with the following, or should I wait some time:
1) In case of an external USB drive, disconnect the hard drive (with "safely remove hardware", even if the cache is turned off), and turn it off.
2) In case of an internal drive (HDD or SSD), reboot Windows, or turn off the computer.
My worry is that if I would disconnect a USB drive, or reboot or turn off the PC in case of an internal drive, before the Chkdsk-related activity is finished, then the file-system of the disk in question could get damaged.
My doubts come from the following facts:
- I have been told that when the Chkdsk results window appears, this means that Chkdsk has finished working with that drive; but I have noticed that some short drive activity is happening some seconds (about 6) after the results window appears (should be a write activity, not sure if also read activity). I noticed this by observing the LED on my USB drives, and also by monitoring the drives in question with Windows 8's new Taskmanager.
- In case of disconnecting USB drives, I have been told that I can be sure that if some drive activity is happening, then the "safely remove hardware" feature won't have effect, and would warn me that there is disk access going on; but I have tried to select "safely remove hardware" while Chkdsk was in the middle of a scan, and the result was that Chkdsk got interrupted (with an error messsage appearing probably from Chkdsk), and the USB hard drive got removed. Though this seems not to have caused any file-system errors (I did another Chkdsk scan later).
You may think that I just need to look at the drive's LED, or monitor the drive's activity with the new Taskmanager, and take note of after how much time the drive activity ceases. Then I would just need to wait so long before disconnecting the USB drive, or rebooting or turning off the PC.
My problem here is that I'm not sure if the new Taskmanager, or the drive's LED, are sensible enough to detect even the smallest disk access, which could get unnoticed. I'm not sure how much I should wait... seconds? Minutes? What do you think? Perhaps there's no need to wait at all?
I did some tests by disconnecting (with "safely remove hardware") a USB drive shortly after doing a Chkdsk on it. Then I did another Chkdsk after turning it on again. I didn't get any error message from Chkdsk. But I'm still worried that there could be an unfortunate moment, during which a disconnection (still with "safely remove hardware") could cause problems, perhaps because in that moment a write operation could be in process.
I think I have read that the new Chkdsk in Windows 8 uses VSS ("Shadow Copy") to check the drives while keeping them online. With this new Chkdsk, I think it is possible to continue using the drive while the scan is happening, even on the system drive.
I was thinking about this: is it possible that the short activity which I have noticed after Chkdsk's results window appears, comes from this Shadow Copy Service, which is "unmounting" (?) the shadow copy used by Chkdsk?
If this is true, is it important to let the "unmounting" task happen, or can I disconnect, reboot, or turn off before it starts? And what happens if I interrupt this "unmounting" task in the middle, while it is in process?
Does it make some sense to wait some time after doing a Chkdsk, or can I at once proceed to disconnect the USB drive, or reboot or turn off the PC (in case of internal drives)?

View 2 Replies View RelatedI have set Defender to do a quick scan in task scheduler for 1 AM. Auto Maintenance is set for 3 AM. I got up this morning to check Defender to verify the newly created quick scan and it was successful but stated it ran at 3 AM. Since I have allowed system to 'wake up' from sleep to do the quick scan, I am afraid the laptop is being awakened at both 1 AM by task scheduler and 3 AM by Auto Maintenance.
It runs as part of Automatic Maintenance, which IIRC runs daily when your computer is idle.
When I put Windows 8 in sleep mode (yes sleep mode...I'm not shutting it off), and I turn it on, it sometimes takes up to 5 minutes to respond to any input. I'm wondering what I can check to make sure the minimal apps/programs are running, and there are no unnecessary memory hogs churning in the background? How can I test it, monitor it, and optimize it?

When I first got my new laptop I made and image using Asus backup restore but all it did was make a copy of the restore partition on the hard drive. Is there a way to make an image of what the computer is with all the data and programs there are installed? I had to do a restore and then I had to reinstall everything and reload all my data files. This took a long time to do. It would be so much easier to just have an image of everything just the way it is now.

I've googled but have most found articles on how to use windows 7 file recovery
How to make a Widows 8.1 DVD disk that works as a recovery disk.What your actually making is an Windows 8.1 Enterprise Evaluation installation disk. When the disk boots up, you select repair disk instead of install. This will give you access to all the repair programs as well as system image recovery option.
All you have to is, go to this webpage (Download Windows 8.1 Enterprise Evaluation) and download the ISO for Windows 8.1 Enterprise evaluation. This will let download the ISO file. Warning, this file is 3.7 gig big and takes a few minutes. After that simply burn to disk. When you boot this disk, just choose repair instead of install. Just note, that like all install disk it takes time to load. 2 minutes and 20seconds on my machine.
