We run windows 2000 server and windows xp. Are the Anti-keyloggers around the web effective? My boss is suddenly very concerned that passwords might be log'd on our servers. I'm not convinced that an anti-keylogger would be effective at all, considering how keyloggers make their way onto systems (ie: physical access, virus, spyware). Is there such an (automated) application that is somewhat effective? I know nothing can be 100%, but some security is better then none sometimes, and this is where we are leaning. Or would something like TeaTimer with SpyBot be better...? Any suggestions/reviews of software or any good input on this topic would be appreciated.

Thanks in advance.
