wp-graphic-captcha-protection

It works great, but, after instal this pluging my host server communicated me that "During a routine scan, the security team discovered infected files". So, I am not sure how it happened, but I know that this company sells plugin to clean infected files.

does what it says! this definitely ups the ante on &$^@($ WP login hackers. however, I hate that bots can still submit the form without completing the captcha. it makes the bot software happy and just creates another entry in my security logs. I want the bot software to blow up in frustration and futility. I would love to see an update that deactivates or hides the submit button until the captcha is successfully entered.
