I have gradually been pruning out my bloatware and my MS ware as much
as I could, and recently canned the MS Windows firewall in favor of
the PC Tools Fiirewall.  That leaves me with one last remaining
dependency: I use the MS Live OneCare Sec. Scan a lot because it
reveals problems and can also help to cure them.  Like fragmentation
and excess userless files.
    Would someone please suggest something along the lines of the MS
Live OneCare Sec. Scan, online, but a whole lot better--doing similar
deep scans and deep fixes better than MS does?  I would like some
suggestions, please.
    Thank you for helping me!
