svchost.exe

I have XP Home Edition.
When I type incorrect web address in my IE,receive message that this site not exist&IE open new
page startnow.com.After that my CPU USE 100% capacity because svchost.exe use 100%.The only way to reduce this capacity is to restart PC.I think that I must do something with IE PROPERTIES but what????
THANKS
