Yes, read the FAQ.

6.1) Why do I get "gpg: Warning: using insecure memory!"

On many systems this program should be installed as setuid(root). This is
necessary to lock memory pages. Locking memory pages prevents the operating
system from writing them to disk and thereby keeping your secret keys really
secret. If you get no warning message about insecure memory your operating
system supports locking without being root. The program drops root privileges
as soon as locked memory is allocated.

On UnixWare 2.x and 7.x you should install GnuPG with the 'plock' privilege
to get the same effect:

filepriv -f plock /path/to/gpg

If you can't or don't want to install GnuPG setuid(root), you can use the
option "--no-secmem-warning" or put

no-secmem-warning 

in your ~/.gnupg/options file (this disables the warning).

On some systems (e.g., Windows) GnuPG does not lock memory pages and older
GnuPG versions (<=1.0.4) issue the warning

gpg: Please note that you don't have secure memory

This warning can't be switched off by the above option because it was thought
to be a too serious issue. However, it confused users too much so the warning
was eventually removed.
