I am looking to implement a Linux Proxy Server and so far have found Squid, which seems to be the leader. My question is does anyone know if there is software I can add to this to detect and remove adware, malware and spyware as well as viruses on the fly when a user accesses a page? We are a Windows shop for our desktops and need to protect them from stuff like this. Currently we have MS Proxy Server version 2 and a really old Mcafee product which is now discontinued and lacking in some features.
Thanks in advance
