The OpenAntivirus Project
It is intended as a co-operation and communication platform for working together, sharing ideas, or re-using existing code. Man power is limited and a KDE-vs-GNOME-ish war between projects won't improve security. Of course competition is welcome and in the end the users will decide which solution fits their requirements best.
Communication will be done mostly via mailing lists. Home of the OpenAntiVirus Project is www.openantivirus.org. Other facilities of communication will be announced as soon as they are available.
