Had to log into two Outlook accounts twice - is this a virus?

I have multiple email accounts that I access from my PC via Outlook 2013. Today, on two different accounts, I had to enter my password for each twice in succession. The first time it was entered for each one, I got the password entry panel pop up immediately after hitting the Enter key. Now it is possible I could have misspelled the respective passwords each time - I did have to backspace initially on each of these logins because I did fat-figure the initial attempts, but I'm almost 100% certain I then typed them in correctly before the first Enter. What I wanted to know is whether this sounds like some sort of known virus or malware that does password stealing. MSE and Malwarebytes run clean, and have been for the longest time.

Here is a look at the Add-Ins for my Outlook setup.

This is not any sort of malware. I have had experienced this issue in the past and it seems to be a bug present in Outlook software.

Did you check the "save my password box"?
