Some anti-virus products (BitDefender, F-Secure, etc) are detecting the version 1.6.1 of the OSSEC Windows Agent as a malware (more specifically Generic.Qhost).
We tried contacting some of them without much success. If you get any warning like that, it is a FALSE POSITIVE and let your anti-virus company know about it.
