I re-installed Avast Free Antivirus application because I did a clean installation of windows. But Avast Passwords doesn’t show up not only in privacy tab but also anywhere. I definitely checked Avast passwords when I customized which to install. (I also installed non-customized version several times.) Strangely, Chrome Extension of Avast Passwords said that it succeed to link to the application. Of course, it doesn’t work properly.
Certainly not recommended. Sorry.
First thing I would have tried is to do a repair.
Repair Avast:
Open the Avast User Interface > Menu > Settings > Troubleshooting > Repair App. > Restart the Computer or,
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed https://www.avast.com/faq.php?article=AVKB204
If Passwords Manager was installed and doesn’t work properly in your browser,
