Attempted Fb Login/pc Admin Login

Hi guys,

I tried to login to my normal account but there were issues with receiving the email. The problem is not mine. My mom's computer has been acting weird.

1. Pop up screen automatically appeared for FB.

2. She said her login screen automatically verified and went to the desktop while she was away from her computer.

I attempted the read me run first post like normal.

However, Avast moved Adwcleaner to the virus chest as soon as it started scanning.

So, I need to know what I should do since I'm failing at the first step. I want to just uninstall Avast, but I don't know what will happen.

There is no possibility for a backup unless I buy a new external hard drive or USB stick.

How do I handle this?
