computer processor running at 100 with windowsupdate.ex program from a folder of Firefox in the app data

My machine keeps suspended running windows 8.1 and Manager tasks indicates windowsupdate.exe current program of running at almost 100%
When I check its properties is in the folder users/app data/roaming/firefox
However the roaming has also a mozilla folder.

When I check my laptop running windows 7 the mozilla folder is ther but not the firefox one

Theis is a real issue and it is the real program or do I have a virus/trojan.
A comprehensive analysis by windows defender can't find anything.

I am able to end Task Manager tasks to correct the machine

Any help would be appreciated.

I Googled, but could find nothing of use

Hello spectra7045, %appdata%\Mozilla should contain your profile firefox real data - as far as I know %appdata%\firefox is not used by firefox or shouldn't be there. I would try to rename/delete that directory and running a full scan of your system with various other security such as the free version of malwarebytes and adwcleanertools.

  • Windows XP CPU running at 100% with no open programs

    I use Windows XP SP3 with 2 GB of RAM with a 1.80 Ghz Pentium 4 processor... The computer is VERY slow and lazy most of the time. Sometimes it's fast and the answer but then IT suddenly comes back to extremely slow and lazy - it's as if something is supported of the processor.

    When we look at the performance tab of the the task manager of the CPU usage is running between 80 and 100% when it opens any program or and for the desktop to appear.

    I ran Super Anti Spyware and found 69 threats that have been deleted.

    I ran Malwarebytes' Anti-Malware and it found 1 threat that has been deleted.

    I run ESET NOD32 Anti-virus and it was a clean analysis.

    I run the latest version of CCleaner and cleaned the registry and the tab Cleaner for the cleaning of temporary files, etc.

    I defraged the drive and also checked/fixed for disk errors.

    After that the CPU usage is running always extremely high with no programs open.

    Does anyone have any ideas as to what I can do or check, fix anything that captures the CPU?

    Thank you. Best regards, Bill Artman Kansas City - USA

    What is your system brand and model?

    You may be able to get clues with what is happening by using the Task Manager and maybe understand.

    You will always figure out what happens if you use Process Explorer.

    Download Process Explorer, so you can see what is 'really' currently running on your system, especially behind these multiple svchosts see you in the Manager of tasks running.

    Download Process Explorer from here:

    http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653.aspx

    You'll like Process Explorer when you get the hang of it.  Process Explorer is the Manager of Windows taskbar on steroids.

    Process Explorer installs nothing so it won't slow down your system since it works only on request.

    Process Explorer can seem a little intimidating at first because it has so much information, but you will begin to make love the way it works when you're looking for performance problems.   You can even say EP you want it to be your new default 'Task Manager' value in the future.  You can always run the original tasks as Manager.

    Once you get Process Explorer running, expand the columns, made drag the corners of the screen for it's largest, etc., so you can see as much information as possible in the window.  Now you can really see what is running on the system.

    Here's a screenshot of my system when I use Process Explorer:

    http://img222.imageshack.us/img222/2567/ProcessExplorer.PNG

    The CPU column is usually the most interesting start with performance issues - which uses the most?

    It is OK and normal to have of multiple svchost processes running, but sometimes malware will hide behind them, as the malware knows that you will not be able to spot it in the Task Manager.

    Malicious software can disguise itself also seems to be a legitimate process of XP or he could hide under/behind other processes that you see running in Task Manager if you can't see the execution.

    The malware would trick you into thinking you must use a System Restore Point, run a repair install or reinstall your XP from scratch when you really don't.

    Looking at the display in process Explorer, you want the CPU most to be associated with the system idle process.  It's 'free time' on your system, so more time there, more free.

    If you look at the graphs of performance and see red spikes (or not) double click the graphic in the upper left corner to display the graph to use.  Move the mouse over any pics to see what are the causes.  Even if the Spike has already scroll screen, you can still move the mouse over the edge to see what caused.  You can also just wait for a pic to happen and then see what caused the Spike.

    To help understand your process svchost and what is running under them, read this article and you will be smarter than the average bear:

    http://www.bleepingcomputer.com/forums/Forum56.html

    Then with a few Google searches, you can watch every thing in PE and behind your svchost processes running and see what it is and decide if your configuration needs it or not and then decide what to do about this.

    If you think you have a svchost.exe process amok, executed using PE, you can right-click that offensive svchost, properties and on the Services tab and son, you can see which runs under it.

    There is a CPU column it will expand (make the wider column) so that you can see CPU.  Maybe you can spot what background process is so CPU consumption under the svchost.exe process.   Stroll under the svchost process and you will find it.

    You can also see what is running under each svchost simply by pointing your mouse on the svchost.exe process.  Some of them have just a things working under them and some will have several things (I hope that all the legitimate XP services) and some will have a lot of things.

    If you have a svchost process that is afflicted, which runs under your afflicted?

    No running process must defy reasonable explanation.

    First, see what you can discover using Process Explorer and then if nothing is obvious, see other things.

    Do, or do not. There is no test.

    I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!

    Hello

    If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

    There is nothing to worry.

  • will choose the manually back option in iTunes backup everything that is on my iPhone to my computer? Including the app data

    Not a problem just a question. I intend to sell my apple iPhone, it's not compatible with my new wireless network. I can't afford to buy an iPhone outright at the moment, but I plan in the future. I want to backup everything on my iPhone to my Mac so that I can restore the data to a new iPhone later. The current iPhone 5 is already set to save important things to iCloud, if I choose the option with a manual backup encryption will be that record everything, including all the data from the app? Sorry if this is a stupid question, I want to just make sure I have everything before you send the iPhone.

    Hello CallRinny,

    I understand that you have a question about your iTunes backups and that you should use. Back on which covers.

    In general, an iTunes backup will cover pretty much everything on your iPhone. The best thing to watch over it, it's what doesn't iTunes back upwards and which covers the encrypted backup. Take a look at the information below to clarify this. I would also do that applications will be recorded in your iTunes library, so when you restore your backup, apps will sync back to the wire in one sitting instead to download on the App Store.

    On safeguards in iCloud and iTunes
    https://support.Apple.com/en-us/HT204136

    backup iTunes

    On your Mac or PC, you can make a backup of your device in iTunes. Synchronize your device with your computer is not the same as performing a backup.

    An iTunes backup includes almost all settings and data from your device. An iTunes backup does not include:

    • Content of the iTunes and App Store or directly downloaded from iBooks PDF files (you can save this content using transfer purchases in iTunes.)
    • Synchronized content from iTunes, as imported MP3s or CDs, videos, books and photos
    • Photos already stored in the cloud, like My Photo Stream and iCloud photo library
    • Tap Settings ID
    • Settings and information Apple pay
    • Data activity, health, and keychain (to save this content, you will need to use iTunes backup encrypted ).

    Learn How to perform backups in iTunes, how to find them on your Mac or PC, and how to delete backups you no longer need.

    My pentium 4 processor works 100% every 18 seconds for 10 seconds. This is due to a microsoft download svchost.exe 1388. I followed varies according to the lines of thought, but I'm unable to stop him. someone at - it help him?

    Instead of using the Task Manager, freeware download "Process Explorer".

  • Problem with convert to PDF from Excel without taking into account the layout and graphics/graphics

    I work with Excel files with graphics (clipart) and charts from the data on the worksheet. I use Excel 2007 and everything a year ago and a half downloaded the option "convert to PDF" on the Microsoft website. It has been working beautifully. In Excel, I've got a) set print area b) go to "adjust to a page" print preview can convert to PDF format and everything on the PDF page looked like exactly as it did in Excel print preview. It worked flawlessly...

    UNTIL...

    .. .the most recent "upgrades" have been installed. Now the menu reads, "Save as PDF or XPS" option and the PDF is a mess. Excel text comes out OK, but any graph or Excel charts will not resize itself, and are completely out of the page. For example, a chart that is supposed to be in the lower right corner must be resized in Excel, placed in the center of the worksheet, on the text and using this approach, resize, save a PDF routine about 50 times, and you can finally wrong PDF resembling the Excel worksheet. Of course, the Excel spreadsheet is totally messed up because you have to move the chart in the spreadsheet and it's a mess, not to mention a waste of time.

    I uninstalled the Converter Microsoft PDF and XPS, and then downloaded and installed the PDF Converter (alone). No luck. It's always a mess. My business is at a standstill until I get this sorted. Help, please!

    KFG

    There is a fix for this.  It is described in a strange article entitled ' Description of the fix Excel 2007 package (Excel-x - none.msp, Graph-x - none.msp, Xlview-x - none.msp): August 25, 2009 "located here: http://support.microsoft.com/kb/973402/

  • Need help with "get-annotation" in a loop by comparing vievents to the vcenter data

    I have a loop in a script that I am running. I used the code that I found on a website earlier. I would add 2 values of annotation, "Department" and "request" to this specific report in each loop run. "." I tried different keys and nothing seems to work for me.

    $created = @()
    
    Get-VIEvent -Start (Get-Date).AddDays(-7) -MaxSamples $samples | `
    Where-Object {$_.Gettype().Name-eq "VmCreatedEvent" -or $_.Gettype().Name-eq "VmBeingClonedEvent" -or $_.Gettype().Name-eq "VmBeingDeployedEvent"} | % {
         $row = "" | Select Date, Msg, User, Cluster, Host
         $row.Date = $_.createdTime
         $row.Msg = $_.fullFormattedMessage
         $row.User = $_.userName
         
         $t = New-Object VMware.Vim.ManagedObjectReference
         $t.type = $_.computeResource.computeResource.type
         $t.Value = $_.computeResource.computeResource.Value
         $row.Cluster = (Get-View $t).Name
       
    
         $t.type = $_.host.host.type
         $t.Value = $_.host.host.Value
         $row.Host = (Get-View $t).Name
        
        if ($row.Cluster -eq $cluster){$created += $row}
    }
    $createdprocessed = ( $created | format-list | out-string)
    

    PS: I don't get my failed attempts because I'm embarrassed. : b

    PPS: I know that my use of loop 2 variable, I keep "created" for other uses later in the script

    I assumed that you ment the custom attributes defined on the guests.

    Then you can do it like this

    $created = @()
    
    Get-VIEvent -Start (Get-Date).AddDays(-7) -MaxSamples $samples | `
    Where-Object {$_.Gettype().Name-eq "VmCreatedEvent" -or $_.Gettype().Name-eq "VmBeingClonedEvent" -or $_.Gettype().Name-eq "VmBeingDeployedEvent"} | % {
         $row = "" | Select Date, Msg, User, Cluster, Host, Department, Application
         $row.Date = $_.createdTime
         $row.Msg = $_.fullFormattedMessage
         $row.User = $_.userName
         $row.Cluster = (Get-View $_.ComputeResource.ComputeResource).Name
         $row.Host = (Get-View $_.Host.Host).Name
         $vm = Get-View $_.VM.VM
         $row.Department = $vm.CustomFields.Item("Department")
         $row.Application = $vm.CustomFields.Item("Application")
    
         if ($row.Cluster -eq $cluster){$created += $row}
    }
    $createdprocessed = ( $created | format-list | out-string)
    

    Note that the recovery of the cluster and the host name can be simplified.

    No need to build the MoRef yourself from scratch.

    Hello

    You did changes to the computer before this problem?

    Step 1: Check if the problem persists in the clean boot state.

    From your computer by using a minimal set of drivers and startup programs so that you can determine if a background program is interfering with your game or program. This type of boot is known as a "clean boot".

    Reference:
    How to configure Windows XP to start in a "clean boot" State
    http://support.Microsoft.com/kb/310353

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    1. click on start and then click Run.
    2. type msconfig and click OK.

    The System Configuration Utility dialog box appears.

    3. click on the tab general, click Normal Startup - load all services and device drivers and then click OK.
    4. When prompted, click on restart to restart the computer.

    Step 2: Also, look for error messages in the event viewer. If you find error messages after return the exact error message so that we can help you better.

    Reference:
    Using the event viewer
