yes, 8 april 2014 Microsoft interrupts the support for windows xp.
This means no more update for windows xp.
Internet explorer 6 was native windows xp so no more updates for ie6.
Anyway internet explorer 6 is not more a safe browser from 10 years.
My suggestion is to use another browser like, google chrome, firefox, safari or opera.
for more info why ie6 is a bad browser
