I was using Chrome as my browser. While in Facebook I saw someone had messaged me. As soon as I clicked on it I got a screen indicating there was a security breach so Microsoft locked my pc. It looked legit but it clearly was a scam to get me to call a bogus support number and who knows what would happen next. Of course I didn't call the number! In the process of purging infected Chrome and switching to Firefox, I lost all of my password information. With so many accounts and passwords I tried a recovery here, but must have used an old email I didn't remember so recovery failed and I had to re-register a new account.
