I run an internet security suite (kaspersky) that monitors applications running on my computer, like most security suites do. Because Mini Rosetta is not digitally signed, Kaspersky assumes that it must be dangerous, and blocks its function. I do not have this problem with any other BOINC project - just Rosetta@home.

Everytime a new version of minirosetta comes out, I have to reassign it's status to "tusted" in Kaspersky.

Please digitally sign your software!

Reply to Samvega - Kaspersky 2010 seems to work with Rosetta.
