Vista - Preventing virus spread

Preventing virus spread

The thought was to do all my work in the guest and nothing in the
host. Both will be XP, fully patched, with firewall and antivirus
protection. The host would be logged in as a limited account and the
guest using an admin account.

I was going to setup a share so that I could copy files from guest to
host. I am looking to limit the risk of virus spread to the host.

Is there anything else I can do to reduce the risk of virus infection?

That's why I have NEVER used my ISP email address. My only public email
address is a Hotmail address. I check my ISP email address every few
months, all that is there are ads and info from my ISP.

People should realize that using an email client on your computer means that
ALL EMAIL GETS DONWLOADED TO YOUR COMPUTER AUTOMATICALLY! This is what the
bad guys want - an open door to YOUR computer!

That's why web email - like Hotmail - is so great. NOTHING gets downloaded
to my computer unless I specifically ask for it, and then it is scanned
before it is downloaded. All the spam and virus infected crap stays on the
Hotmail servers.

Re: Preventing virus spread

Thanks guys for confirming. I'm not so worried about getting a virus
myself, It's more the kids now have just started using the internet
and with their inexperience, I suspect there will be a good chance.

That's why I though VM was the best way to go so that if the guest
does get infected, we can start over....I just want to ensure that the
virus gets contained and doesn't spread to the host.

So they must have done something stupid, but of course they won't ADMIT to
doing something stupid. Like clicking on a popup window that asks to
check your system for malware, etc. You don't get infected from simply
browsing, unless you are running IE5 in Windows 2000 or something equally
ancient.

Yes, you do get infected, at least scareware/malware, from simple
browsing on reputable web sites. And her system was right up to date
with the patches, IE version, etc, etc.

Besides sneaker net is still an excellent means of passing viruses and
trojans. The US military found several USB thumb drives in the
parking lot of, or public areas near, important military buildings,
such as the Pentagon. And those thumb drives contained trojans which
allegedly were connecting to IP addresses in China.

I can recall seeing viruses on floppy drives. Indeed there's a virus
burnt on a CD which came with a 12 year old Microsoft book.

ScareWare gives you a pop-up warning saying your system is infected
with X viruses!! Click here to download antivirusware to clean your
system.

Explanations.

No way I'm posting a direct link to any website with malware on a
public forum though.

Popup blockers aren't 100% effective unfortunately. The scareware
variety are pretty nefarious and confuse a user into doing something
stupid, it's social engineering it's true, but it's actually pretty
convincing. The X doesn't close it, the "Close" button doesn't,
nothing will get rid of it short of using the task manger to cancel
the IE process or a forced shutdown -- not a lot of my users are
capable of handling that. My users call me and I come get them out of
it but what about all those people that have no know how? (All my
users have popup blockers enabled of course and all the latest patches
no less.) Not a lot of them would think of a forced power down and
that's really the safest thing for them to do.

Maybe because if we knew we'd already have had them taken down...

Just go surfing on some warez sites for awhile and you'll hit one
eventually.

I don't know of any because I've never had such. And no these are
not cookies.

Here's a description of it along with a screen shot.
