Infact it's a Slack 7.1 with 2.4.2 kernel I on P III with 256. I am running game servers, Apache and Mysql - but I don't think that is any help for the issue, except for that I want to get some performance too . I have a LAN of about 30 PCs with Wins which wil use Internet throug the Slack . So I want to do something about the viruses in the LAN.
