Tip: Tohelp prevent future malware infections, Stop using IE as your main browser. 
Switch to a more secure, less malware prone browser as your main browser. IE is extremely 
vulnerable to malware infections. 

Firefox and Opera are recommended alternatives by security experts. Additionally, 
use a HOSTS file. See the link below for more info.
