Hi Friends,

I am having a certain problem developing an application that checks whether certain important windows processes like winlogon.exe, services.exe etc have been altered by a certain malicious file. The malicious files inject their code in these processes. Does there exist any method to detect this change. I tried a hash value mechanism but it did not succeed as the after and before hash values turn out to be same.

need ideas and suggestions. thnx

There's no way to do it in .NET. You'd have to write something to redirect calls to the I/O functions to your code, then on to the original functions. SysInternals ProcMon does this very thing.

Seriously, just get a decent antivirus package and be done with this.
