Wscsvc.exe - password stealer and banker trojan?

Internet Explorer has been locking up, a high memory and CPU usage program runs, then IE returns after an irritating time period. A program is running called wscsvc.exe and a site says it is a dangerous program, a password stealer and known as a 'banker trojan.'  The site gives a fix (download and install HijackThis Installer from CNet).  I'm a Norton 360 subscriber, everything is up to date.  Any ideas or knowledge of this program?
