Windows 7: Windows Defender Turns Itself Off

Windows Defender Turns Itself Off

Nine times out of ten, when I log off, or when the screen saver kicks in, Windows Defender turns itself off.


Possibly, this is a malfunction built into my Dell Inspiron 5720 laptop, which has other peculiar abnormal operational characteristics.


If, however, this is a problem encountered by other users, I would surely be grateful to learn how to fix it.

1.)Download security check below.

This will show me what security software you use and what the status is of services such as windows firewall:

Downloading SecurityCheck

Open and run: SecurityCheck.exe
Follow the instructions inside the window that appears.

When done, a Notepad report opens automatically, called: checkup.txt

Please post the checkup.txt in your reply using the paperclip:

OBTW, when I attempt to go there, I am advised, "Windows Security Center can't be started."

When I attempt to run sfc /scannow I am advised, "You must be an administrator running a console session in order to use the sfc utility."

I am the onlyh user of this PC, and I am the Administrator.

Yeah, that confuses some folks, what you are doing by running as administrator is elevating from the user level to the system root level.

Elevated Command Prompt

So to run the SFC you need to elevate and "Run as Admin" before it will work because you are checking system files.

SFC /SCANNOW Command - System File Checker

Just right click before launching the cmd and select "Run as Admin" and it will work.

I see two anti virus programs. That will cause all kinds of problems.
McAfee is probably turning off the firewall.

I will go back to lurking.

Good eye Jack, MSE will turn off defender.

Two AV's aren't a good idea either, it looks like it says the firewall is enabled though.

1.) Good job guys. Just as mentioned above please do the following:

-Uninstall mcafee.
-Uninstall Java. Java is a huge security risk and is unnecessary for the average user.
-Uninstall adobe reader and flash. Adobe reader is an unnecessary program and additional security risk as most web browsers can open pdfs without adobe reader. We can install adobe flash later once we clean you from malware.

2.) Click start, type services in the search box. Click services. When the service window opens, browse and look for a service called security center. Click the name of the service, and click start on the left hand side. If it starts with no errors, double click the service and change the startup type to automatic (delayed start) as that is the default state the service is set to startup as.

3.) I suspect you to be infected with malware.

Please read this entirely before we begin malware removal:


Before we start with malware assistance, I want to inform you of a few things:

1.) I am not a recognized malware removal expert. I do not have a certification from a malware removal school. Having said that, I have removed a lot of malware with PCs and have years of experience.
But just like no antivirus program is 100% effective, neither am I. My goal is to simply clean up your PC from any malware, and assist you in any way possible to help you secure your PC.

2.) Sevenforums (This forum)and I will NOT be held responsible for anything that might go wrong with your pc.

3.) You agree to follow all directions given, until I advise that your pc is clean and you are free of threats. You will not abandon the thread.

4.)

Do you agree to these terms?

If yes, reply with a Yes. If not, please state so and I will flag an official malware remover, or I will recommend another place for malware removal assistance.
