openantivirus.png OpenAntiVirus is an open source antivirus definitions project along with java based scanners. What’s interesting about this project is that this is one of the few open source initiatives for antivirus protection and does a pretty decent job at detection.
There are also third party developer scanners that are written to take the OAV virus detection files and it basically takes care of any sort of dilemma you may have without having to shell out for an expensive commercial antivirus product. To be frank, I personally like non-Java based scanners better, but it does allow for multi-platform almost immediately. That is a good thing.
