We have several remote developers who are working on our code and have access to our FTP server. Recently someone copied an infected file to the FTP server and virus spread throughout the whole FTP server. We can't install antivirus on the FTP server.
We can't force people to install an Internet Security Tool (e.g. Norton, Gdata, Kaspersky) on every machine because most of our remote employees have their own computers and own software. So I am looking for some audit tool - I want to make employees test their own computer once in a while.
I know there is "Trojan Remover" which scans the computer. Is it enough or maybe you can recommend better solution?
