Computer Suddenly Stopped Connecting to the Internet

[MissionsEdge]

My wife's Windows 7 x64 Toshiba computer has stopped suddenly connecting to the internet.  The wifi monitor in the lower right hand corner of the screen says it is connected to a network and has access to internet.  However, no browser will connect to the internet.  

 

It was working fine and then all of a sudden about 3 days ago it quit working. I have tried various removal services but nothing has worked.  It feels like a virus or malware but I have no idea what it is.  I have had her run logs and here they are.

You can d/l and transfer the following to sick PC via USB stick or similar media...

 

Download Farbar Recovery Scan Tool and save it to your desktop.

 

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
  
• Press Scan button.

Next,

 

Download Farbar Service Scanner from here: http://www.bleepingcomputer.com/download/farbar-service-scanner/dl/62/ and run it on the computer with the issue.

Make sure the following options are checked:

 

• 
  

Internet Services
Windows Firewall
System Restore
Security Center/Action Center
Windows Update
Windows Defender

 

• 
  

Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.
Please copy and paste the log to your reply.

Greetings.  Thanks for helping me with this.

 

 I know my wife's machine is  windows 7 x64.  However, the FRST64 would not run on her machine.  When I tried to run it on her machine, I got this message "c:\users\EDGE\desktop\frst64.exe is not a valid Win32 application".  So I tried the 32 bit version and I get the same message.  Where should I go from here?

I have tried this.  I got the command window open in repair mode and it gave the same message as before.  What can I try now?

[kevinf80]

Create the Widows Defender Offline Tool, I give the instructions to load to a USB flash drive.

 

Download the tool from here :- http://windows.microsoft.com/en-US/windows/what-is-windows-defender-offline and save to the Desktop.

 

You will have to select the correct version for your system, either 32 or 64 bit

Run the tool, Windows 7 or Vista user right click and select "Run as Administrator"

Read the instructions in the new window and select "Next"

 

 

In the new window accept the agreement:

 

 

In the new window select your USB Flash Drive, then select "Next"

 

 

In the new window ensure you Flash drive is selected, if not click on "Refresh" then select "Next"

 

 

In the new window accept the formatting alert by selecting "Next"

 

 

Files will be Downloaded:

 

 

Files will be processed and created

 

 

Flash drive will be formatted and prepared

 

 

Files will be added to the Flash Drive and the tool will be created.

 

 

The procedure is finished and the Tool created, click on "Finish" to complete.

 

 

Plug the USB into the sick PC and boot up, if it does not boot from the flash drive change the boot options as required,  Use F12 as it boots, change options...

As it boots you`ll see files being loaded and the windows splash screen, eventually the tool will run a "Quick Scan" follow the prompts and deal with what it finds.

When complete do a full scan, deal with what it finds.

When finished, remove the USB stick then press the Esc key to boot into regular windows.

Navigate to the following file:

"C:\Windows\Windows Defender Offline\Support\MPLog-MM/DD/YYYY-HH/MM/SS .txt"

 

Open with notepad and copy and paste it into a reply.
