Due to a recent issue with a virus that I've hopefully finally eradicated from my computer, I've been searching through my registry editor and researching some entries online that seem iffy. I know next to nothing about programming, so I'm reluctant to make any changes until I can be sure that what I'm looking at really needs changing, but I've come across a few anomalous files that I can't make heads or tails of. I haven't been able to find any concrete information about them so far, so I was wondering if there's anyone here who could shed some light on what they are and what they do.

Again, I'm not quite computer savvy, so please bear with any mistakes I make while trying to outline my operating system (if that's the right term) and these files. I have an HP Windows Vista Home Premium.

A few of these files have nothing in them besides value name (Default), type REG_SZ, and data (value not set):

The other mystery files have some information in them including subfolders and codes, but I'm not sure which information might be irrelevant to know. Please let me know if I need to give some more info on these:

HKEY_CLASSES_ROOT\soap | value name (Default) - data "SOAP Moniker"
HKEY_CLASSES_ROOT\Spp.Spp | value name (Default) - data "SPP Class"
HKEY_CLASSES_ROOT\Spp.Spp.1 | value name (Default) - data "SPP Class"
HKEY_CLASSES_ROOT\Unknown | value names (Default), AlwaysShowExt, QueryClassStore, TypeOverlay - no data

They relate to Windows' handling of file extensions, eg:


HKEY_CLASSES_ROOT\Unknown is for handling files of undefined extension.
