logically let see what is it

if antivir=fruit
and if avast = orange
and if avira = apple
if i request apple*printf("avira")
if i request orange*printf("avast")
if i request fruit*printf("avast or avira")
so meaning if i request antivir it can be avast or avira
and if i request avast it mean i need exactly avast!!!
correct me if i'm wrong
Best regards!!!
