I found it. It's "register ware" now. I guess some would call this "not free" but I didn't pay for it.
One of my computers is running slow as molasses.
Been using Avast for years. Ran it the other day on that machine and it came up with a virus and I sent it to the chest.
Today, it started up scanning memory, etc. and then just disappeared. Went to the Avast site and it looks like to only option there is for a paid edition now.
Downloaded AVG but didn't install it yet; I'm kinda leary after seeing another user's problem with it.
