Help with svchost.exe (possible trojan) - read details please?

September 1st, 2008 · No Comments

In the last day now, I’ve seen on my task manager that svchost.exe appears 7 times - under user name SYSTEM 4 times, LOCAL SERVICE once, and NETWORK SERVICE twice. The memory usages vary from 1000 K to 48000 K.

Remember, this is new - and my CPU usage is high now, regularly 70%. I see on wikipedia this article http://en.wikipedia.org/wiki/Svchost
but I need some extra help from you all. I am now running McAffee virus scan, though I’m not sure that will do the job. And I don’t want to just close the processes, for fear of messing up my computer.

Also, I need some help understanding this wikipedia article. I am decent with computers, but not like that
It says: “Due to being widespread among running processes, svchost.exe has long been a common disguise used by malware to hide its presence from the user. (One of the common trojan horses deceptively uses scvhost.exe). Users may then run tasklist with no arguments and match the reported PIDs with the previously shown Svchost instances. If memory usage appears abnormal, the user can look up the service names shown by their command on the internet to see if it is a known service or malware.”

And what am I supposed to do after I find out which malware it is?
Please help me out. It would also be good if someone good with these things could message me or I message you to get further help, because this definitely is something not good on my computer, from where I know not.

THANKS
