For how long have you had this problem?

Have you tried a System Restore to a day before this problem started?

Have you run sfc /scannow from a command prompt?

here is a solution that helped me:
go to command prompt and write this command:
cd\
c:\> attrib -r -h -s autorun.inf
c:\> del autorun.inf
d:\> attrib -r -h -s autorun.inf
d:\> del autorun.inf
restart the pc
