[dba-Tech] AV Updates

Well thats a theoretical statement.

If your all the computers of your company use the same scanner and are
updated how could an old virusdefinition scanner (from the outdated)
bypass an new virusdefinition on your network? Excatly, not.

Furthermore, some virusses are stealth to the scanner. So if you update
the old pc your are never gonna be sure it is infected or not because
the update is post infection. You will only notice when checking the
logs on your server when that computer puts file on it.
>From my point of view you are getting into extrimities updating
computers like that and further more it does not or not much give you
more garanties....

If your server is protect and your workstation you have a double
protection when an infected computer gets on the network.

Thanks for replying Erwin.

Points 1 & 2 - thanks for the ideas. Will think about those.

Point 3 - mmm. I take your point, but my gut instinct is that it'd take
a strong nerve. Doesn't everyone, for example, insist that floppy disks
are virus scanned before going near the network? Isn't that the same
principle?
Shouldn't one make every attempt not to let anything infected connect to
the network rather than connecting and then allowing the av software to
shout?
I'm not sure of that, I'm just wanting to tap into others' experiences
and asking for feedback.
