I have tried to run this on my development server but it failed.
MD5 of hashes-2.9-rare.php:
Warning: md5_file({path-to}\wp-content\plugins\exploit-scanner/hashes-2.9-rare.php) [function.md5-file.php]: failed to open stream: No such file or directory in {path-to}\wp-content\plugins\exploit-scanner\exploit-scanner.php on line 64
Suggestion of next version:
1) Check if current version of WordPress is supported, if not show appropriate message for non-supported version.
2) Add option to admin screen to increase/change the memory limit if possible.

As a good practice one should never run the development version in production. I am not going run code that does not run in development and testing into a production server.
