Missing entries

events

  1. my password to enter my MacBook account no longer worked (separate issue, but mentioning it for completeness).
  2. I reset the password through my Apple ID.
  3. Following instructions I reestablished keychain synchronization and google interface and pictures synch.
  4. once back inside and going to one of my frequent sites, I noticed the avast key symbol was missing.
  5. I opened the avast passwords app and found that over half of my site entries were missing.

thoughts?
