My Kaspersky Internet security is doing the same on ALL my machines. If it cannot be signed or a wildcard fix done soon. I will have to remove rosetta from my project list, which I do not want to have to do. I have been doing them for quite a while, but it is a pain having to go to each machine and add move each to Low Restricted everytime the version changes.

In the case of Rosetta, what Kaspersky need to provide is the ability to say "Don't bother checking for a signature on files that match this wildcard."

The purpose of signatures is twofold:

1. If a file shows up with a virus and a valid signature, you now know where the virus came from.

2. If a file shows up with an invalid signature, it has been tampered with, and therefore should be rejected.

Case 2 is the far more common scenario, and is the main reason why Kaspersky is unwilling to let Rosetta run. It has no signature, and therefore there's no way to determine if it's been tampered with.

That said, in the case of Rosetta the likelihood of tampering is zero, since BOINC itself verifies that the file saved to your disk is what was sent from the server, plus the fact that you always download directly from the project website.

What should be done is to contact Kaspersky and ask them to add this feature. ESET's NOD32 has a very similar feature, which has proven very useful at times.
