Hello,

I have a Host Win7 Home Premiun x64 and a Guest Centos 5.5 x64.

My problem is when I copy a file for my guest,
ex: on host File.zip has CRC 20304050
on guest same File.zip has CRC 90807060

someone had this problem?

I try transfer via SMB, network, shared folder...

Security software installed that might mess around with such files like anti-virus or firewall?

Yes,
I'm use "Kaspersky Internet Security 11.0.1.400"
This version can cause the wrong?

thx

Deactivate it, then you know it.

Kaspersky is known to cause problems with VB, so yes, there is a good chance that is the cause.
