Angels have the Phone Box
Yes, my pic is from a while ago (I have been using Defender for quite some time. ) That's fine.
Sounds good. I will be AFK (away from keyboard) for a while now, so take your time.
Keep the computer in a clean boot state, except for Avast (let that one start), and hopefully the disk thrashing won't be such a problem as you work through the other things on the list. As you need/open programs, you may notice that they take a little longer to initialize. This is typical of a clean boot - all that stuff doesn't start at boot and run in the background.
No problem at all. I get a LOT of help on this forum, (and sister forums), so I pay it forward when I can. If I can help, I try, time permitting.
