RE: Anti Virus for Debian

You're talking about removing viruses though. I'm talking about preventing them. Anybody can manually remove a virus from a Windows machine, it's really easy. I can even remove W95.MTX (The Matrix) virus in 5 minutes. I'm not sure of any network admin that wants to spend their time removing viruses though. I think the easiest way to go about virus safety is just make it more difficult to get a virus. Thus disabling scripting. Of course many of Microsoft's auto updates are kind enough to enable it again. That's why you use a program like Autoinstall to role out your updates. ;)

After ILOVEYOU first came out and AV vendors didn't have a fix for it, we
had to figure out a way to quickly disable the virus. So I spent 5min
finding the reg key and writing 2 scripts to make the default action Edit,
instead of Open, and another in reverse, make the default action Open
instead of Edit. I wouldn't suggest renaming wscript.exe, jscript.exe or
csscript.exe, as Critical Updates, Repairing, or Upgrading IE will just put
those files back in place. The javascripts are attached, take a peek and see
if they fit the bill. If not, at least you still have the option to quickly
disable VBS scripting :)

Speaking of Windows and *.vbs attacks. What you should really do is disable
the scripting host on all of your Windows machines.  For those of you who
don't know, you can just rename "wscript.exe" "jscript.exe" and
"cscript.exe".  There's a good chance you'll only have one of them.
