microsd adapter is not reading on my laptop

its a brand new laptop i have only had it for about a year the card used to work on it and recently my virus protection software found a worm…but i couldnt figure out what was wrong with it before that so i deleted pics, music, ect… like i said it used to work on it but i think i might have deleted something on accident and now i cant figure out what i need to download or whatever to fix it… its an HP g60 notebook
