'Twould be nice if we could post screenshots here, but I guess the bandwidth would more rapidly exhaust.
This post in the Avast forum contains a fairly comprehensive explanation, and the thread contains a couple of screenshots that may help.
The scan report I get at the end of a scan is in a blue media-player-type explorer window, with minimize/maximize/X at the top right corner. Unfortunately I couldn't find an example to post.
That your entries are too large to read it all even with the column headers dragged suggests a number of characters representative of a system restore point. Which means a search won't find it.
If you click the entry in such a way that the whole thing (as far as you can see) turns grey, try copying then pasting it to notepad/clipboard.
Ccleaner: "Options>Cookies" Drag the ones you want to keep to the whitelist. Do that after logging on to any sites you want to remain logged on.
Confirm that "System Restore" is turned off on all drives? Or at least the drive scanned? If it is on for another partition of the same drive, I
think it will still be referenced somehow by the partition the OS is on.
The other option includes reference to the protected files in the antispyware programs. To know that you'd have to see the path.
[edit] BTW, the freebies I have on my computer, which include the apps you reference (except AdAware, which won't be permitted the disk space ever again until hell freezes over, or there is peace in the middle east, or a new clean green energy source is cheaply available to all, or until I really really feel like it,) and they give me a good deal fewer problems (= zero) than some experienced by my friends that have paid applications. Free doesn't have to mean nasty/faulty/limited.
