Problems with false logins

[strugglingnovice]

I'm getting several fake registrations daily in my shopping cart, mostly coming in the middle of the night. A lot of them using Alabama as a state, some are overseas.

Here is an example of what I'm getting:

COWOA_SECTION_HEADING
COWOA_STATUS_FALSE

First Name: PeYroVZaJsNXhW
Last Name: rztBFCbNEdAM
Company Name: FcEfRPONDoTVg
Suburb: jaiogfmGwOS
Post Code: ocDuhURyNK
City: UxnfjHVFrPWSeh
State: Alabama

It's always garbled like this and i'm getting about 10-20 per day, so frustrating.

What can I do to stop this. I'm using Zen Cart v1.5.5f and my template is Westminster New.

Thanks for any help you can offer. Jan
