viruses, company

Yes, we have a fairly tolerant site manager and lan admin (i'm backup company lan administrator and the manager/administrator of the unix/linux/gould systems). WE've gotten a few backdoor viruses and lots of email ones, one was attached to an internal web site for some reason, can't figure that one out yet, on our main server but the ip is open only to internal users!. We are slowly educating ppl on viruses, attachments. We use lotus notes and winxp but we have a few bad apples in teh bunch that are constantly downloading movies, music, games etc. So far the boss has been pretty tolerant but he's about at the point he's going to cut off internet to most workers. I wish he would, would cause less headaches for some of us. We've had a couple of hard drives wiped out just this last month supposedly thanks to viruses. Irritating and definitely causes downtime and problems. Most of our browsing/internet is all on XP computers, the unix/linux is internal and for development, needs to be secure from viruses and safe so no access out, so its more that I use the windows to get the proper files i need for unix/linux and then move them over to the unix/linux boxes as needed. SO just wanted a warm fuzzy on security of some of the main/official web sites. I appreciate the comments, thanks!

WALL(1)                                                            User Commands                                                           WALL(1)

NAME
wall - write a message to all users SYNOPSIS
wall [-n] [-t timeout] [-g group] [message | file] DESCRIPTION
wall displays a message, or the contents of a file, or otherwise its standard input, on the terminals of all currently logged in users. The command will wrap lines that are longer than 79 characters. Short lines are whitespace padded to have 79 characters. The command will always put a carriage return and new line at the end of each line. Only the superuser can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies messages. Reading from a file is refused when the invoker is not superuser and the program is set-user-ID or set-group-ID. OPTIONS
-n, --nobanner Suppress the banner. -t, --timeout timeout Abandon the write attempt to the terminals after timeout seconds. This timeout must be a positive integer. The default value is 300 seconds, which is a legacy from the time when people ran terminals over modem lines. -g, --group group Limit printing message to members of group defined as a group argument. The argument can be group name or GID. -V, --version Display version information and exit. -h, --help Display help text and exit. NOTES
Some sessions, such as wdm, that have in the beginning of utmp(5) ut_type data a ':' character will not get the message from wall. This is done to avoid write errors. SEE ALSO
mesg(1), talk(1), write(1), shutdown(8) HISTORY
A wall command appeared in Version 7 AT&T UNIX. AVAILABILITY
The wall command is part of the util-linux package and is available from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util- linux/>. util-linux August 2013 WALL(1)
