Windows 10 Home (1511)

64-BitOS

 

I've had Windows for a few months now and never really had an issue until the past few days. Overall CPU performance/speed is way down. Firefox freezes then recoops every 2-3 minutes, adobe plugin constantly crashing, even to do things offline is crazy slow.

 

I downloaded Windows Defender probably a week or 2 ago and that is the only big change that I know of done on this computer. I used to run Malewarebytes, SuperAnti-Spyware and Advanced Windows SystemCare. But was told that Advanced Windows SystemCare was the devil and to try TFC (temp file cleaner) & MyDefrag instead. So now i'm running;

 

Windows Defender

MalewareBytes (free)

SuperAnti-Spyware(free)

TFC

MyDefrag

 

Is this combination making my computer un usable? Or something else? Please help.

 

Thank you in advance for any help!

Hi detruence :)

Windows Defender is built-in Windows 10 (and Windows Vista, 7, 8 and 8.1 as well). Are you sure you downloaded Windows Defender, or was it another program with a similar name? Can you tell me where you downloaded it from?

If you want your computer to run quickly, don't download all this unnecessary software. As Aura says, Windows Defender is included with Windows 10, as is automatic defragging. If you feel they are a problem, temporary files can be removed with the built-in disk cleanup tool. I would remove all the utilties you've installed, and run a full scan with malwarebytes in case of one the "utilities" is rogue software.

Adam,

 

Malwarebytes Antimalware and SuperAntiSpyware are very well known utilities with sterling reputations that serve very useful purposes, particularly should you find yourself in the unfortunate position of somehow having acquired malware or spyware.

 

Windows Defender, I presume, is the built-in Microsoft antivirus package, though the original post does make that muddled.

 

None of those three products is rogue software and MBAM ans SuperAntiSpyware are routinely recommended and employed on during disaster cleanup situations.  See the "Am I infected" and related forums to see just how often.

 

I have no idea about TFC and MyDefrag and share your reasoning that the latter is absolutely unnecessary since Windows has been doing automatic defragmentation for some time now.

 

I know that CCleaner (provided you don't use the registry optimization) is a much better disc cleaning tool than the built-in disc cleanup tool and TFC may be as well.  That should be made clear in the other forums as well, but since I don't need it since I use CCleaner I'm not going to research it further.

It's definitly Windows Defender. Is there a way it was disabled before? I just remember trying to install MSE and through research finding out that on Windows 10 there is no MSE and only Windows Defender. Don't remember what I did but after I did it I got a new Defender icon on my homepage lol. Sorry for the lack of memory. Maybe it was always active and just wasn't on my desktop yet, I really don't know.

 

But my main problem is the state of the computer now, it's to the point where certain things don't even work correctly or web pages won't load correctly. It went from running fine to like this within less than 48 hours.

 

Thanks for your time btw! :guitar:

detruence,

 

         If you know precisely when you tried "working your magic that's turned out not to be" then I would suggest that you do a system restore using a restore point from a date/time you know to be earlier than that.

 

         Control Panel -> System -> System Protection link on the upper left side -> System Restore Button  

 

         If the default restore point is later than you want it to be then follow the steps to choose an earlier one (which are pretty obvious).  If the restore works then report back that it has.  If it fails, or it fails to get you out of this situation, report that back, too.

It's possible that Windows Defender was disabled. It shouldn't disable itself automatically however: did (or do you) you have another Antivirus program installed prior to "installing" Windows Defender? And what do you mean by "Defender icon on my homepage"? What homepage? In Microsoft Edge? Internet Explorer? Start Menu?

I have no problem getting rid of TFC and MyDefrag they're pointless with everything Windows has built in, but i've had them for months now. And my computer has gone to sh*t fairly rapidly in the past day or so. I don't think TFC and MyDefrag are the root cause of my specific issue.

I didn't have MSE enabled on my previous version of Windows, maybe thats why it was disabled. And no I haven't had anything installed besides; SuperAntiSpyware, Malwarebytes, TFC and MyDefrag.

 

Didn't mean homepage, I meant the desktop.

 

Realizing that I didn't "install" Defender i'm thinking my issue prob isn't a conflict of protection programs or Defender, sounds like a virus or maleware issue right?

It sounds like it to me. Are you able to take a screenshot of that Defender icon and post it here? Also, if you right-click on the icon and select Properties, where is the targetted file or URL for it?

This is the legitimate executable for Windows Defender, so you didn't download a malware or anything when getting that icon added to your desktop. Alright, follow the instructions below please.

  • Download MiniToolBox and move the file to your Desktop;
  • Right-click on MiniToolBox.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Check the following options:
    • Flush DNS;
    • Report IE Proxy Settings;
    • Reset IE Proxy Settings;
    • Report FF Proxy Settings;
    • Reset FF Proxy Settings;
    • List content of Hosts;
    • List IP Configuration;
    • List Winsock Entries;
    • List Last 10 Event Viewer Errors;
    • List Installed Programs;
    • List Devices - Only Problems;
    • List Users, Partitions and Memory size;
