Brand new laptop whirring constantly, 100% CPU usage

Hi guys,

I have a brand new laptop that was working fine until Norton trial ran out, and someone (definitely not me), came and viewed porn on it (but not me).

Now everything loads slowly and takes time to respond, sometimes even when I am typing in a browser my words just lag, its unbelievable.  

Sometimes it even freezes for the fun of it!  AndI have to manually power off not even Task Manager shortcut works!  Hooray for technology!!

 When I go into task manager, disk use and memory are both usually at 100%, even if I only have firefox open (with about 4-5 tabs but no more).   I also noticed the laptop is constantly making a whirring noise, like it would make if just opening a new program.  If anyone wants furhter deets I can send a graph of performance and the billion and one programs I can see it running in task manager.   Even when I try to close some of the unwanted programs in task manager they just pop back up a moment later!!  (E.g cortana).  And Im sick of having to read about a specific way to disable a specific program like this from starting up when there are so many of them.  

What have I tried? I'm running Windows 10 and have tried basic trouble shooting only- defrag, reinstall Norton and run a full scan (nothing came up, sadly), and use Absolute Installer to uninstall the dumb crap Windows 10 shoves down our throats.  And of course power off and reboot.

Finally, I'm a reasonably smart guy and try to avoid potential malware sites or spam.  I also have plenty of disk space i've installed maybe 10 games on steam but still got plenty of HD space.  Other than that i've installed very little apart from MS word which I paid for.

I'm wondering what else I can do because this laptop is literally only two months old.  I'm thinking it might be best to just reinstall a new O.S like Linus etc?  Or I could try system restore but I don't wanat to have to backup data etc.

Please help!  I'm patient and kind of understand computers,  (probably not an expert as some of you guys) but the fact that its Windows 10 and brand new and acting like a dying old PC just grinds my gears so much you have no idea.   

Cheers
Chris

Have you ran a full virus scan with something like Malwarebytes? If someone did view porn on it, it likely could be infected by something.

Hi, if you suspect your infected you should go to our "am I infected forum". I suspect though if you totally remove Norton (you will need to google for their uninstall util, it is essential for properly removing Norton) all your problems will go away. Windows defender now offers as good as, if not superior protection to any third party AV, without the integration problems.

Thanks guys!

 

Is Malwarebytes the only AV I will need do you think?  I want to be as thorough as possible so I can feel more in control of this problem and not have to fork out 1000 Billion dollars to some IT on the corner-shop who charges what he likes.  Bastard.

If you are going to uninstall Norton, which I would suggest in any case, you will need to use the Norton Removal Tool.  As previously suggested, Windows Defender is an excellent replacement for an antivirus.
 
If you believe that this computer may be infected you need to have this topic moved to the Am I Infected, What Do I Do? forum.  The type of scans that you will need to run are not allowed in the Windows forums.  I will request that this topic be moved to this forum so the scans suggested below can be run and their logs posted.
 
Please do the following scans in the order they are requested.  Post all of your logs (unless specifically requested) in your topic.   Please do not wrap your logs in quotes or code brackets or use use spoilers.
 
 
Please download and run RKill

RKill is an easy to use tool that kills known processes and removes Windows Registry entries that stop a user from using their normal security applications.  RKill will not remove any of the processes it stops, you will need to run security scans to remove any malware found.  These settings will remain until the computer is rebooted, for this reason you must run your security applications before the computer is rebooted.  

Please download RKill and install it.

When RKill is run it will display a console screen similar to the one below:

After this has run you will see another image explaining that RKill has finished running and you should be able to run the scan.  You need to click/tap on OK.

When RKill has finished running a log will be displayed showing all of the processes that were terminated by RKill.

AttentionAt this time you need to run your security applications listed below.  When the scan has finished running a lot will be posted in Notepad.  Copy and paste this log in your topic.

Importanat: There is a possibility that malware may recognize RKill and keep it from running, if this is the case do the following.

If while RKill is running you may see a message from the malware stating that the program could not be run because it is a virus or is infected.  This is the malware trying to protect itself.  Two methods that you can try to get past this and allow RKill to run are:

1)  Rename Rkill so that it has a .com extension.

2)  Download a version that is already renamed as files that are commonly white-listed by malware. The main Rkill download page contains individual links to renamed versions.  

After the application has run successfully and color=blue]you have run the requested scans[/color] you should reboot the computer to restore the processes and Windows Registry entries.
 
 
Please run Malwarebytes AntiMalware

Please download Malwarebytes Anti-Malware 2.2.

1)  Double-click on mbam-setup.exe, then click on Run to install the application, follow the prompts through the installation.

2)  Malwarebytes will automatically open.  You will see an image like the one below, click on Update Now.

3)  Click on Settings, you will see a image like the one below.

When Settings opens click on Detection and Protection, then under Non-Malware Protection, click on the down arrow for PUP (Potentially Unwanted Programs) detections and select Treat detections as malware.  Under Detection Options place a check in the box for Scan for rootkits

4)  Click on Scan (next to Settings), then click on Scan Now.  The scan will automatically run now.

5)  When the scan is complete the results will be displayed.  Click on Delete All.

6)  Please post the Malwarebytes log.

To find the Malwarebytes log do the following.  Copy and paste the log in your topic.

*Open Malwarebytes Anti-Malware.
*Click the Scan Tab at the top.
*Click the View detailed log link on the right.
*Click Copy to Clipboard at the bottom...come back to this thread, click Add Reply, then right-click and choose Paste.
*Alternatively, you can click Export and save the log as a .txt file on yout Desktop or another location.
*Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

 
 
Please download AdwCleaner and install it.

When AdwCleaner opens click on Scan to start the scan.

Once the search is complete a list of the pending items will be displayed.  If you see any which you do not want removed, remove the check mark next to it.

If there are no malicious programs are found you will receive a message informing you of this.  
 
Click on Clean to remove the selected items.  If you have any questions about any items in the list please copy and paste the list in your topic so we can review it.

You will receive a message telling you that all programs will be closed so that the infections can be removed.  Click on OK.  The computer will be restarted to complete the cleaning process.
 
When the cleaning process is complete a log of what was removed will be presented.  Please copy and the paste this log in your topic.


Please run the ESET OnlineScan

This scan takes quite a long time to run, so be prepared to allow this to run
till it is completed.

***Please note. If you run this scan using Internet Explorer you won't need
to download the Eset Smartinstaller.***

  • Place a checkmark in YES, I accept the Terms of Use, then click Start. Wait for ESET Online Scanner to load its components.

    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • Click Start to begin scanning.
  • ESET Online Scanner will start downloading signatures and scan. Please be patient, as this scan can take quite some time.
