Avoid signed assembly network access

I'm using a .net assembly that was digitally signed (using comodo), and I noticed that the f开发者_如何学JAVAirst time my application loads the assembly it connects to 'ocsp.usertrust.com' and 'crl.comodoca.com'.

Is there a way to avoid these connections?

It may be automatically checking for revocation of the certificate. There's an option for this in IE - Tools > Internet Options > Advanced > Security > Check For Publisher's Certificate Revocation

It is just verifying the cert. The problem is???? Unsign the assembly, if you can, or block the port or address.

But what is the problem?
