Avast Software Updater Password

On turning on my computer today, I saw that I was no longer the only ‘User’ shown on the front page.

There are now TWO users, me and ‘Avast Software Updater’!!

I tried to log in, to my own computer, as Avast, but it needs a password that I do not have! I tried my normal ones, but nothing.

I am still able to log in to my normal user account, but I am wondering what this new user account is for, and why ?

I assume this happened when the update to Avast 8 was done.


Curiosity about how long I have been happily using Avast made me look to see how old Avast is…
