I don't know when it is happened first time, my hosts.txt file constantly modified and detected my Security program(AhnLab Safe Transaction[AST]. this program is necessery for Internet Banking in Korea.)
AST detected hosts file modification, and the IP address which added in hosts.txt
119.207.66.177 r6015597.iavs9x.u.avast.com
119.207.65.63 n4464433.vpsnitro.u.avast.com
(Another IP added, I'll constantly update it)
and similiar IPs every other time.
I can choose options between save hosts file or rollback it, and I chosed both options but it constantly happening.
Is this really Avast's behavior or something else? What should I do?
