For first few minutes is worked for me. Then I tried to close and open skype and same problem is here again.
I checked in Task Manager the processes and it showed multiple skype processes and end task command couldn't close it.

Even worse... I was looking through control panel and noticed that window defender cannot be opened. "This app has bet turned off and isn't monitoring your computer."

PC is malware clean, any update on Skype?

[Michael (alan1998)]

Skype has issues sometimes. I've run into login issues with it. Just time and patience can fix it.

With Twins help. Try adding it to the exclusions of your Anti-Virus program.

Skype is still buggy and windows defender still somehow doesn't work.

[TwinHeadedEagle]

Windows Defender won't work, because there is Avast installed?

About skype, tell me exactly what is the version and behaving...
