deleting adware search.counter?

Norton has identified adware on my C drive (homepage hijacker).
It cannot delete the two identified files.
These file do not appear when I look for them by tracking their path...(the files are hh.htt and tips.ini) to delete them in accordance to the solution suggested by symantec
Do you know how I can get rid of these files or solve the prob.
