Security Software Download Script

This is a long one.
At my last job, we had a file server that I’d set up that held a number of security tools we used during virus scans (as well as installs, general tools, etc.). Keeping all those tools updated was a bit of a pain, so I wrote a script that downloaded them all for us.
Note: this is basically a braindump of the script, so while I tried really hard to keep it reasonably portable while I was writing it, your mileage may vary…
#!/bin/sh
#calling any of the following as a command switch will download them individually
# a2
# ComboFix
# Avira
# Smitfraud
# SuperAntiSpyware
# SDFix
# VIPRE
# RKill
# DrWeb
# AVGRescue
# BitDefender
# Kaspersky
# Norman
# RootkitTools
#Otherwise, the DAILY or WEEKLY variables will work

Another note: The Vipre Rescue Scanner portion of the script was designed to be used with a GUI I wrote for the Vipre Scanner (since Sunbelt didn’t think it was necessary). You can find downloads (and code) for that project here.
Edit: A brief recognition that with one or two lines at the beginning of the script, I could remove all of the » $LOGFILE bits in there and make it far more readable…I wish I would have noticed that then.
