svchost - what are these services?

SO I recently had what Microsoft say is the "rare" XP bug of the svchost going nuts and taking up 99% of my CPU.

I found a fix, which seems to be working, and finally manage to download something that tells me which svchost services were actually running (Tasklist).

The problem is I have no idea what most of these things are, and any attempt to Google them only gives me results of people saying they have trouble with it. Nothing that tells me what they are, or i they're good or bad.

I therefore ask you people. Below is the list of services my laptop is currently running. Can anyone tell me what the hell they are? Are there any I should really drop?

Thanks.

The full list from Tasklist is:

svchost.exe

DcomLaunch

TermService

RpcSs

AudioSrv

Browser

CryptSvc

Dhcp

ERSvc

EventSystem

FastUserSwitchingCompatibility

helpsvc

HidServ

LanmanServer

lanmanworkstation

Netman

Nla

RasMan

Schedule

seclogon

SENS

SharedAccess

ShellHWDetection

srservice

TapiSrv

Themes

TrkWks

W32Time

winmgmt

wscsvc

wuauserv

WZCSVC

WudfSvc

Dnscache

LmHosts

SSDPSRV

WebClient

BthServ

stisvc

更新:

Can anyone be more specific and helpful?

I'm wanting to k now EXACTLY which, if any, of these services are dodgy. I'm NOT looking for suggestions on scanners or fixes, just information on these specific services.

    Dude you have at least one trojan running in there its is used by russian criminals to steal BANKING information, its a keylogger that only activated when the user enters credit card details.

    You need the trial version of Kasperky, because superantimalware and antimalware bytes both detect the trojan but CANT remove it, kaspersky can. nod32 can too eset security - but you wont be able to install it with that infection so use kaspersky instead - free 30 day trial.

    Once cleaned up you need to go with the original disk and run sfc /scannow and do all the updates again. You then need to think about your anitvirus software and firewall. Avira would have blocked this trojan and comodo would block it trying to access the net. Avast wont install while its on there but will remove it had it been installed!

    CLEANING might or might not get rid of the infection.

    If it is serious, then your ONLY hope is a complete wipe the disk and re-install.

    You are hacked.

    download superantispyware portable on a different computer, disconnect the questionable computer from the internet and clean it with superantispyware.
