User Comments

I have installed Zillya Internet Security, but I am very annoyed with the ZavCore.exe *32 which is running actively with 25% CPU usage at all times. Anyone having a solution, please help. I did remove, reinstalled it, nothing worked. It is the only antivirus program on my computer and I have purchased it legally.
