Problem with computer disc?

i have this problem. i cannot access my local disc C: and D: by double clicking after a virus scan. everytime i do so, it asks me to choose a program to open in the "open with" dialog box. however, if i browse using the window and choose the windows explorer to "open with" the disc, it worked just like normal. this happened after i made a virus scan. what i think happened is that the antivirus deleted the autorun.inf along with the virus.can i still open the disc with double click or do i need to manually select the windows explorer everytime i open local discs
