Title: UI Failed to load and internet issues.
Post by: REDACTED on September 12, 2018, 11:33:42 AM

I've got a lot of problems out of the blue.
- AVAST Free Antivirus' UI constantly fails to load, troubleshooting steps don't work.
- AVclean (the uninstalling thing) spits out an error, and the first time I tried using it, I gave up after trying about ten times, then i just rebooted my out of safe mode pc to normal mode, and AVAST worked again, later that day turned the PC off, next day booted it up, and AVAST stopped working... again. after that AVclean did nothing.
- Mozilla Firefox can't load ANY webpages since AVAST stopped working..? Chrome&Edge work fine, but I am so used to Firefox that I want Firefox back. It just keeps loading, loading, loading, and never stops. it doesn't even give a timeout.
- Avast plugin in Firefox is greyed out, while it isn't in chrome. in Firefox clicking it doesn't do anything, while it works as intended in Chrome.
- Avast won't do anything related to the internet either.

All these problems happend out of nowhere after a normal windows boot.
In services.msc the Remote Desktop service is set to automatic, as they told me to do in the troubleshooter for the AVAST UI.

Can someone help me please? I am scared because not a single troubleshooting guide works.


PS. Thanks for the laughter AVAST with the "This is really embarrassing" message.  ;)


EDIT: If you need any information, just ask.

Version: 18.6.2349 build 18.6.3983.371
OS: Windows 10 64 bit version 10.0.17134.285
After the problem happend I installed Malwarebytes, before that I only used AVAST.
Before AVAST I didn't have any other antivirus (excluding Windows Defender), because I installed AVAST immediately when I got this device.
I don't have any other security related software.

IMPORTANT NOTE

I forgot to say that my computer won't shut down anymore. I now have to force it off.
