Re: How to detect that the application itself is modifed.

Tech-Archive recommends: Speed Up your PC by fixing your registry

Moreover, if it was virus that targeted .Net exe, they would surely "resign"
your app with it's own private key and app would load and run on way - with
what ever code the virus injected. Currently, the best you can do obfuscate
your code and sign it. Not fool proof, but raises the bar.
