I'm new to the forums so forgive me if for some reason this is in the wrong place but I'm having trouble with Scvhost, I'm nearly 100% certain a virus or the like is running from it, and has been for sometime.
Many months ago I started seeing that my CPU was at 100%, and was slowing everything else down considerably. I paid no mind to it for the longest time, that is until I learned malware can run hidden within Scvhost, and cause many, many problems with it.
The Svchost instance in question takes up almost all of my available CPU, and does so often, when I forcefully end the process it simply restarts a few minutes later, rinse repeat, not working evidently.
I went of CNET and downloaded a little program called "Svchost Process Analyzer", it listed all of the Svchost running and told me what they where doing, it even flagged four of them as suspicious, and two of the four refused to display and information about them, including where they where, citing "I wasn't the administrator", I'm the only active account on my PC, and should have full Admin rights.
At this point I'm probably sounded like a broken record, as I'm sure I'm about the one millionth newb to ask this here, but I just need to make sure I know what I have to do to fix this mess.
I've heard people say the best thing to do is to download Combofix and let it run and find the malware and delete it, but experience has taught me to only believe a piece of anything I see on the internet.
Getting to the point of this post, can some direct me to a step by step guide as to how to rid myself of the Svchost virus and keep it gone for good. I’ve had to reinstall my Operating System to fix a very bad attack years ago, and would like to avoid doing it again (It caused some problems of its own, asking me to choose which OS to boot every time I fire up my PC, but that’s a another post in and of itself.)
For those interested I have a stock Dell E310, and run Windows XP Home Service Package 3.
Thank you in advance for any help that can be rendered,
EDIT: On a possibly related note, I for some reason have no sound now... It says I have no Sound Device, I'm not sure if this is related or not...
