Taskbar shows no internet connection but it's working (except for Inte

Hello,

My desktop computer with just one wired network connector has developed a strange problem.

When I turn it on the taskbar internet icon shows no connection. For a while it just displays a spinning circle then either shows a yellow exclamation sign or more often a red cross.

However, e-mail, Onedrive, Firefox and Chrome work OK.

Strangely though clicking on Internet Explorer does nothing - it does not run or even attempt to as far as I can see.

Attempting to access Network and Sharing Centre from the Control Panel fails - the program does not start and I just get a spinning circle.

When I shut down the computer I get the message that otther programs are running, but task manager does not show any.

When I select force shut down the screen clears but the computer does not shut down, so I have to use the reset button on the computer.

The next time I start the computer I get the message that Windows did not shut down correctly, so start it in Safe Mode with Networking.

Initially the internet icon shows a Yellow exclamation mark, but this clears after a few seconds.

When I shut down the computer and re-start it normally (i.e. not in Safe Mode) it works correctly, i.e. the network icon in the taskbar is OK and Internet Explorer works OK as does the Network and Sharing Centre.

However, when it is shut down and re-started the problem come back and the only way to clear it is to do another start in Safe Mode with Networking and then re-start normally.

Any advice on curing this would be appreciated.

Thanks for the reply.

Malwarebytes found some PUP's which were removed, A full scan by Kaspersky found nothing.

Now for the two batch files.

While they will run when the computer shows no issues on the network icon, they will not run when the network icon is showing the spinning circle.

All that happens is that I get another spinning circle when I click on them in the download folder.

Furthermore, I can not then open any other explorer windows and have to go through the reset button and re-start in safe mode again to clear the problem.


Have attached the two files when there is no problem with the computer for info.

Thanks for reply - at least I know what the files should look like when it's working OK.


I believe I have only installed 3 programs recently, but can't recall when the problem started.


The programs are software for a USB microscope, software for monitoring my UPS external power supply, and software for a SDR receiver which I finally got set up last night.


There should be restore points, but as the computer is not working correctly at the moment I can't view them so will have to go through the re-start in Safe Mode again to check.

Hi Nick,

next 2 things to run
from an elevated command mode - sfc/scannow
KB947821.

Note
if your system specs are correct re IE8 then i suspect that Kapersky is blocking it - way outta date
turn it of in programs/features then features (top left)

Hi all,

Done a System Restore to a point before I installed the three programs mentioned above.

On completion System Restore reported that the restore had failed and nothing was removed.

Looking at the Restore option it still shows the programs listed - see attached image - I selected to restore to when the USB Microscope was installed, so expected every thing above this to have been deleted.

However, as far as I can see they have been removed, at least from the Desktop.....

Anyway, whether the Restore operation completed successfully or not, the problem seems to have been cured.

I have re-started the computer about 6 times so far and the network icon in the taskbar shows with no errors at any time so far.

Internet Explorer (Version 11) starts every time as does the Network and Sharing Centre.

I will re-install the programs one at a time over the next few days and check after each install the problem does not reappear. Hopefully this will show me which one was causing the problem....

Regards,

Nick.
