Designte.com virus

Help, I have a virus that keeps bringing me to a website called designte.com, which is a website for a bogus software solution to solve the virus it keeps giving me!  I cannot access the internet on this computer....as a matter of fact, I can't do anything on this computer unless it is in safe mode.  How can I download Norton Antivirus on one computer and then load it up on this laptop so I can eradicate the virus?

 

Help me please!!!
