In a manner that is not holy or morally right; wickedly.

Unholily → It is formed from "un-" (meaning not) and "holy" (from Old English "halig", meaning sacred or consecrated) and the suffix "-ly" (meaning in a manner). The word "unholily" means in a manner that is not sacred or consecrated.
Think of 'not' ('un-') being added to 'holy' to remember that 'unholily' means acting in a way that is not sacred.
