    With the Log Parser one can scan logs, whitelist out legitimate, non-corrupt entries (usually file paths), and apply a standard format to a log generated by any antivirus or malware-removal program. This makes for easier reading of the meat in any log.

    mod_detect

    Detects changes to your Website, finds malware

    I have several websites and some time ago I found code in one of my websites that I did not create. One of those scripts was able to send spam and the other one had some malware code in it. Now you can argue that my website was just not safe enough because who ever placed this code had been able to get in. That is true and the ideal situation is to have such a safe website that nobody can break in. But sometimes this is hard to achieve. mod_detect was developed to at least find code that someone else placed into the scripts of your website and eventually eliminate it.
