Waterfox Update

Running Win 10

Waterfox asked me to update which I did but now it will not work, I have deleted and re-installed but it still will not work. I get a page with "new tab" flashing on top left corner but any address I put in nothing happens.
I think this is more than just a problem with waterfox update, my printer will not print unless I restart my pc and after I sign in as it loads it prints.
I have been into windows security to do a scan and it works for about 25 seconds and then stops and will not go any further the same with Malwarebytes it gets to scanning file system and just hangs

Thanks for any help.

Thanks for your e-mail

Having trouble following instructions. Malwarebytes is downloaded but the file "mbam-setup.exe" is not there, tried to turn off AV but it will not let me I get the message "
"administrater" is blocking this page and MGtools will not run I just get the message do you want to run this program click yes and it just goes back to the message.
When I click "using Malwarebytes Anti-malware" I get an error page.
Not sure what to do next.

FRST64 was blocked because it could harm your device.

I have just got a message to "restart to install the newest windows feature update", is this wise and if not how do I stop it?

 

I did not knowingly download this update it just messaged me to restart to install.
Have paused it until next month.

Hi thanks for your e-mail.
I am not on a limited account, I am English but live in France, not sure if that makes any difference.

I am not on a limited account what ever is on my PC is stopping me from logging into my Administrative account. I am not in an office its just me at home on my PC.

I went into Windows security > virus and threat protection > virus and threat protection settings and the on off switch was there but when I tried to move it a got a message saying "only an admin can change this setting" Now when I go back to that page there is no switch and against all the options it says "no actions needed"

 

It says credential manager.

 

Hi.
Please find attached logs that I managed to get.
Hitmanpro ran until "classifying 99%" and was stuck on "c:\windows\winhlp32.exe"
MGtools would not download.

 

Have run Zemana it found nothing, went to reports and there is nothing there, I can see a box with Date & Time but it is empty, should I run it again?
