malware scanner

[xchrix]

hello

how do you protect your servers from malware. i hat the problem that someone installed bad php scripts at an wbespace of a customer. so my ip got listed at a badware index site. so all sites are shown as untrusty because they all have the same ip. i have removed the malware and now i have to wait that google checks again..

do you know some scanner like rkhunter that this doesnt happen again??
