In what way does antiviral medication lead to bacterial infections?

Not usual antivirals. Common antiviral medications such as Zovirax or Valtrex (valacyclovir) used to treat herpes viruses, or Tamiflu used to treat influenza viruses, do not lead to bacterial infections. Certain medications that suppress a person's immune system, such as prednisone, are sometimes used to decrease inflammation caused by some viral infections. With immunosuppressant meds, a person may get other infections more easily.
