Crypt/modify a .sys ?

10x for your great information's guys and girls

Have someone to share a good Code Virtualizer or vmprotect ? I have an old version of Code Virtualizer but seem to not work

I'm not so skilled like you guys and girls but an little tutorial: how to update/rebuild the checksum after I pack/crypt ?

I need to modify size for prevent a stupid detection method who check size&CRC, CRC to modify is simple in fact but if I modify size or CRC the windows don't accept my .sys tell me: isn't a win 32 bit

Edit:

I solve the problem for 32 bit platform (IDA Pro(.MAP File) + Code Virtualizer) so 10x for great information guys and girls !
So only for made a comparison, have someone vmprotect ?(last version?)

A little tutorial: how to update/rebuild the checksum after I pack/crypt ?(to learn for myself)

Solved CRC&Size
