Avast 

A free antivirus program that i use, developed by Czech computer technology that tends to update your virus database very often, and tell you about it pretty much daily and can get a little annoying, though it is a decent program that works and is free.

Avast! virus database has been updated!

Avastin 

The first drug in a new class designed to treat cancer by compromising its blood supply. Avastin (bevacizumab) is believed to prevent angiogenesis, the formation of new blood vessels that supply the tumor with blood, oxygen and other nutrients and allow the tumor to grow and metastasize to other sites in the body. Additionally, Avastin may interfere with tumor growth by causing blood vessels to shrink away from a tumor.

nf2 = lots of fucking surgery
nf2 + avastin = let's hope to hell my tumors fucking shrink!

Koravellium Avast 

A storming dragon, that's what. An immortal dragon from Yolen. AND she used to date a human.

My dumbass after looking up 'Koravellium Avast':"So was someone gonna tell me Cultivation is a bloody dragon? Or was I supposed to find out randomly while browsing the Coppermind Wiki?"
