"Windows 7 USB DVD Download Tool

The first link is the README, the second link the download.

If you operate that tool from a 64-bit OS, it can make
32 bit or 64 bit USB sticks from
32 bit ISO or 64 bit ISO files.


Super Paul! Thanks a lot. Both the old and the new install are/will be
64 bit

Default Antivirus during fresh install of Windows7

Paul, I am connected to internet via a fibre-modem with a built in
router. Delivered by my ISP. I have only done changes to the wi-fi
part of it, and can't say if it's got a firewall. But an indication
that is has some protection is that I for tears have run virtual
XP-machines in Oracle Virtualbox without any problems. They are all
connected to internet, and I have not bothered to install antivirus
software on all.

Most of what you write below is way over my head, but it gives me some
hints. But as Good Guy writes: I am too stupid to run a Windows
system.

Hope I won't get killed for top-posting, but think it is appropriate
here.

Besty regards

Or connected to a modem/router, with the router NAT cone
to protect you ?

If you used a router, a lot of trivial stuff can be stopped.
SASSER would be stopped. SMB attacks would be stopped (because
I don't think a router by default opens the Windows file sharing
port - that would be a terrible feature!!!). My first router
had IDENTD not stealthed, but that could be fixed with
a port forwarding rule. I read somewhere it was a bad idea
to leave it visible, but I've not read of a means of
exploiting it.

You should:

1) Be using IPV4 (because of coincidental NAT with IPV4 on ruter).
2) Be using a router, between the Internet and your computer
(for the NAT, the network address translation). By matching
outgoing ports to incoming ports, plus stateful packet inspection,
it's possible to do a decent job of "hardening" your Internet side.

It's not clear to me, other than security-by-obscurity (the 4 billion
local addresses), how IPV6 can be made to afford the same level of
coincidental protection.

I know there are some idiots out there, running Windows connected
directly to just the modem portion, then relying on the
Windows Firewall to protect them, but that's like this...

"The Windows Firewall... Wile E Coyote"

https://en.wikipedia.org/wiki/File:T...screencap).jpg

All you need is for one clever Black Hat to find an exploit
for the Windows Firewall, and then you're cooked.

While looking up SASSER yesterday, I see there are more
worm exploits out there than I was expecting. SASSER alone wouldn't
be an issue unless you were installing one of the older OSes.
But some of the others might actually need to be patched,
to make the machine safe. In which case, a person could
prepare a "patch kit" with WSUSOffline and inject ~150 security
updates via a USB stick. I've done that before. It takes a while,
no matter how you do it.

HTH,
Paul

Yes, probably some people believe that. Some people believe the earth
is flat. Some people believe all sorts of false things. "Installing
antivirus software weakens the OS" is one of the many false things
that some people believe.

Totally agree with you there.


Also, a lot of
problems come from AV interfering with things.



Another false thing.


Not 100% in agreement with you there - well, I suppose it depends on the
interpretation of "a lot". Certainly, AV software _does_ interfere with
things, although modern software (both the AV and the other
applications) have improved a lot in recent years, such that you're less
likely to encounter such problems than you were a few years ago. (A lot
of the reason being changes in the OSs themselves, which now don't allow
software to do things older ones did, so it's more that modern OSs do
the "interfering" than the AV stuff doing it.)

However if you run two or more anti-virus
programs, yes, they can interfere with each other.


You'd think that, in that if nothing else they'd see each others'
signature tables and ring bells; and I've certainly seen reports of
people who have experienced problems (mainly huge slowdown rather than
false reporting); however, I _think_ I've also seen people who say they
are running two or more without problems.

But I should point out that not all anti-virus programs are equally
good. Undoubtedly some of the poorer ones *can* cause problems.


Yes, they vary. (And the "best" aren't always the most popular, or most
advertised.)

Some people also believe that if you practice "safe hex," an
anti-virus program isn't necessary. That *is* correct. However (and
it's a *big* however) unless you *never* go to the Internet and
*never* insert CDs, DVDs, external hard drives, thumb drives, etc.,
you can never be completely sure you are always practicing safe hex.
Rather than hoping you are always practicing safe hex it's wise to not
only do what you think is safe hex, but also run an anti-virus
program. As far as I'm concerned, not running an anti-virus program
is the height of foolishness. It's better to be safe than sorry.


Yes, I'm fairly careful, but have had the odd popup from an AV. (Usually
just when downloading, unpacking, or similar, before actually running
anything.)

As far as I'm concerned, the two most popular and most advertised,
Norton and McAfee, are also among the poorest.
