1. Password was only used for skype, it was "blocks12", was set around 5 or 6 years ago only for skype, I have moved to password management apps lately and all my current passwords are 20+ character generated strings and if two step authentication is available I always choose it. However I completely forgot about skype since I opened it so many years ago.

2. I have it already installed.

Should I reinstall OSx or is it just a skype hack?

[edit] when I went to download the adobe update - turns out I already have it installed...
