Hello, for years the free crystallographic software Jana (http://jana.fzu.cz) is significantly slowed down by ESET NOD antivirus. The other antivirus programs do not slow down Jana2006. We usually advice users to remove the directory where Jana is installed from the scan. However, with growing use of ESET NOD antivirus it is often installed for the whole institution with blocked advanced setting. As a member of developer's team of Jana I would be very grateful to the ESET developers if they could have a look at the Jana code and find a way how to make it working normally with ESET. It is now concern of several hundreds users of Jana2006 suffering with extremely slow functioning of the program.
