Yes, you most likely have an anti-virus software package such as Sophros
running that is modifying st_mtime or st_ctime while "visiting" the
files. Most these packages have a way to reset the times so that they
remain unchanged after inspection. In the case of Sopros, you need to
specify "--no-reset-atime" (yes, that is *no* reset ...).
