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.
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?
I have a new Dell Inspiron 15r as of this Christmas, running Windows 8. I ran the upgrade to 8.1 but I still have a problem with my cursor wanting to "hover click" on links or browser tabs, as well as being stuck in the down position, when I'm not even pressing on the touchpad left button. I end up selecting an entire region of stuff while moving the cursor across the screen.
I can't figure out what to change or configure in Control Panel, or is it in the Dell Touchpad configuration utility?
In Control Panel/Ease of Access Center/Make Your Mouse Easier To Use I have unchecked "Activate a Window by hovering over it with a mouse." Still happens.
Scanning device is an HP Photosmart All in One HP 2575. i first installed it as an USB device and Windows Fax and Scan recognized it and scanned nicely. I then installed it as a network device and WFS would not recognize it as a scanning device when I unplugged the USB cable. It prints just fine but will not scan.
I need to email scanned copies of different things. I can scan them ok, but I am having a hard time emailing them. I have tried setting up my gmail account in the scan setting window with no luck. With another program (paper port) I could just drag the file into the email - this won't work in the windows fax and scan program.
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)?
I know that Windows Fax and Scan is not an ideal solution for scanning, but I'd like to avoid installing additional third party software, if possible.
WF&S works fine with my (Canon) scanner. It scans without a hitch. However, it is only able to use the default scan profile. If I try to create my own scan profile, I get this message:
"Windows can't load your scan profile. Your profile settings might not be compatible with this scanner."
I know that my intended profile settings (600 dpi, scan to PDF) are compatible with my scanner. How can I get WF&S to create a profile with my settings?
I've once again encountered this problem with my Canon PIXMA MP620 printer/scanner: when using it wirelessly, it can't print. According to 'Devices And Printers', it's offline and therefore most programs I use in Windows 8.1 claim it can't print.
However, using Canon's program 'MP Navigator', it can scan from the printer without any problems. I can scan from the computer to the printer and the other way around. Therefore I'm suspecting that the problems lies with Windows 8.1 and not the printer. The connection is obviously there but Windows doesn't seem to think so.
I can't find a solution in the printer's manual, Windows doesn't give me anything when I try to troubleshoot the printer in question, and Canon's own 'Network IJ Tool' can find the printer but says it's doesn't work without clarifying why.
I spent more than two days trying to get my Brother MFC-7460 printer (than scans perfectly in Windows 7) to scan with PaperPort, but no dice! That is until "my2cents"
Long story short, I've lifted the beginning of the support page that says the following:
The following Nuance products are compatible and supported on Windows 8:
Note PaperPort Professional 14 and PaperPort 14 at the end of the list. Well . . . that ain't perzackly true!
Scrolling down (which I didn't do, because I believed what I was reading) you find:
Scan button is grayed out within PaperPort. This issue can be resolved by running the Scanner Connection Utility. See Technote 6937 for additional information.
I have a Windows 8 Toshiba Satellite S855-S5377 laptop. My problem is that I get notified all the time by the Windows Action Center that I should scan my drive for errors even though I already have multiple times. I've already opened the command prompt and typed chkdsk /f /r and did the scan on boot up. I checked the log with the Computer Management Console and didn't find any problems with the hard drive. I also have used other HDD error checking tools and have even used the error checking utility of Windows when you right click the drive choose properties then tools. And every time the PC or the program says my drive is fine but the Action Center warning message doesn't go away.
When I run the assistant I got and internal error msg and the program stops running. I tried turn off my antivirus but that didn't work. It reads Internal Error:Error retrieving the scan report. I'm running Windows 7 Home Premium 64 bit.
How do I scan from a Sharp mx-m362n to a user's computer on the same network domain? Nothing in the operation manual shows how to perform a scan from the machine's control panel
I am trying to refresh my windows 8 ,but when i tried to do so it didn't work and i got this error "there was a problem refreshing your pc no changes made".
I tried to do Sfc /Scannow using Admin CMD but i got this
"Windows Resource Protection could not start the repair service."
Finally I tried to fix the services using "Dism /Online /Cleanup-Image /RestoreHealth"
And I got this error:
"DISM>>Error: 0x80004002 DISM failed. No operation was performed. For more information, review the log file. The DISM log file can be found at C:WindowsLogsDISMdism.log"
How to fix the windows or without reinstalling it ? I'm using Windows 8 i tried to upgrade to 8.1 but didnt work also.
Applied new SSD to Laptop but can't use the Product key as I don't know what it is as it's in the BIOS. Key is needed for Windows defender to function.
How to I uninstall windows defender. I have disabled it however it is still running. I look in event log and it says unable to stop windows defender. It posts error 16 every 5 minutes. I have disabled it when I try to open it it says it is disabled. I really wouldn't care except several times a day my app will freeze. They always coincide with the windows defender error. I am running windows 8.1.
I have 3 viruses detected on my last full PC scan which was moments ago.
Viruses and Trojans Quarantined: Artemis!7F706C6E8821 ^ This code cannot be found on the Mcafee website. ^ This code was given when the scan was finished, this is the code for the trojan, virus I have?
When I turn on my Toshiba Satellite laptop, it does not see my i-phone hotspot. Wi-Fi status says "No Wi-Fi connections available". I always have to turn the hotspot off and then back on after the laptop is up and running for the laptop to find it. This does not happen with my desktop. It sees the i-phone hotspot without the need to cycle the hotspot off and back on, so I'm thinking that it has to do with the Toshiba rather than the i-phone. Both laptop and desktop are running Windows 8. Not a big problem, but I thought some one may know of a setting which I need to change.
I have my HP 8500 Pro set up to print, but I cannot scan. Any word on how to do this? When I went to scan/fax, it says that I have no scanner hooked up.
I too got rid of Norton, but I still have another a/v suite on my Toshiba laptop. Should Windows Defender be activated? A tech person at the company told me there would be no conflict, but that it's up to me.
In general, is it a good idea to have both running?
I have recently built a PC myself and had no issues whatsoever, until the other day when an Action Centre notification popped up. For some reason, Spyware and Virus protection have both turned off automatically and when I am prompted to turn them back on, I get an error saying "Action Centre can't turn on Windows Defender. Please try again later."
I have tried the services.msc method and tried to activate WinDefend that way, but encounter another error "Windows could not start the WinDefend service on Local Computer. Error 2: The system cannot find the file specified."
I have looked up this issue with no resolution yet - as most of the solutions are for people that have installed third party Protection Programs like AVG, Norton etc.
I haven't installed any programs like that, and have also checked in the Control Panel to make sure one didn't install itself automatically with an install of another program.
