[NCLUG] Linux Alternatives & Necessities for Home Use

[Walker, Philip M (Optical Storage)]

Hi, I'm Phil Walker.
I've been lurking on this list for a few weeks.

For recovering deleted files (photos, or whatever), one alternative is
to search the raw device (not sure what that would be, offhand, for a
flash card) for the magic numbers in the header.  Then, if you're lucky
and the file contents are contiguous (and if no portions of the deleted
file were reallocated to other photos), you experimentally copy various
lengths, examining the results.

Here's a dump of the top of one of my JPEG files:

00000000  ff d8 ff e0 00 10 4a 46 49 46 00 01 01 01 00 60

Well, I know I'm facing a much friendlier internet when I get off the
Windows bandwagon, but I'm sure *some* viruses/worms/etc. are written
for linux/unix environments.  Mozilla-core browsers have security flaws,
too....  

Surely the FOSS world has some sort of package available to protect
desktop linux machines from dimwitted end users surfing and reading
email?  Because you have to choose between "desktop linux revolution"
and "there are no dimwitted linux users" - you can't have a revolution
without dimwits ;^)

It looks like Clam AV (clamav.net) is one option; anyone have experience
with that or want to suggest alternatives?
