They're quite possibly both fine old chap - go to Control Panel> Administrative Tools > System to check whats running and why. svchost is just a generic term for a collection of process running in tandem. As for background processes you're not sure about - jot down the name of anything you think is suspect. Go to Search and track down exactly where on your system it is (mostly the sorts of things you're after lurk in Windows> Pre-Fetch). Check the properties of the file, see where it originates from. If you're still unsure, zip the driver or .exe you're unsure about first then delete the original. Setting a Restore Point first is always a good idea. This way, if something conks out because of the deletion you can always reinstall from the zip file and have it ready for re-deletion should it transpire to be a thing you don't want. As for unwanted active X controls - Open IE, Tools> Manage add-ons. Can't remember if this is a feature pre-SP2, so forgive if it isn't, but you'll find all registered active X controls and browser extensions, both current and pending, logged here. Disable whatever you're not sure of. Check Windows Firewall - if your using Broadband y'do need to pick up a copy of Zone Alarm asap, but for now just check the exceptions tab, see whats listed as being allowed to connect out. Anything y'don't recognise/don't want/aren't sure about - un-tick the box or delete from the exceptions list. You're locked down reasonably well until you can get something better. Download SpyBot Search & Destroy 1.4 and Ad-Aware SE from www.download.com asap - SpyBot is now very, very good and comes with a resident shield, as well as a browser plug-in to stop nasties attaching themselves to IE when on line. If you can't find a copy of SP2 with a PC magazine at your local news agents, order on on CD direct from Microsoft - details at Microsoft.com. The real question everyone wants to know is: is your system staying up now, or is it still conking out after a spell? PS: http://www.theeldergeek.com/ Go, now, read.
