While the Roman Rite may have dropped the Prayer to St. Michael the Archangel, the Maronite Rite views purification as part of the journey to the Kingdom. The prayer from the Sunday of the Deceased Priests, implies that the journey is difficult and never free of danger until the end.
...Grant peace and serenity to the priests
who have gone before us to your holy dwellings.
May their works precede them as a record of their faith
and a memorial of their lives.
May the Evil One flee at the sight of their coming
from the path that leads to you.
Let none of your deceased ministers be tempted
by the devil and his legions.
May the marks of your holy Mysteries
shelter and protect them on their journey to you ...
In the Roman rite, the prayer to St Michael is still said (as part of the Leonine prayers) after Low Mass:
"Saint Michael, the archangel defend us in battle; be thou our safeguard against the wickedness and snares of the devil. May God rebuke him we humbly pray and do thou, O prince of the heavenly host by the power of God, thrust down into hell, satan and all the evil spirits who prowl about the world for the ruin of souls."
Pope Leo XIII mandated this (adapted short exorcism) prayer after a vision of the devil attempting to take control of the Church.
Pope Leo XIII also wrote several encyclicals on the importance of the rosary which is another powerful weapon against the evil empire.
As part of his devotion to the holy rosary, Pope Leo XIII established the Confraternity of the Holy Rosary.

Of course, I would be remiss if I didn't at the same time once again mention the Universal Living Rosary (under the patronage of dearly beloved St Philomena):
