Unauthorized users using my internet connection

How do I keep strangers from logging onto my computer through my DSL
connection? When I go to sign out of windows I get a message that other users
are logged onto my computer. This is after I have been on the internet.
Verizon says this is an XP problem.
Thanks,

You should really learn how to use a News Client such as Outlook Express to access this an
other News Groups and other News Server. Then you can access the Verizon PRIVATE ;
0.verizon.security and 0.verizon.adsl News Group to get Verizon specific assistance.

Your post doesn't make much sense. Are you letting starngers come into your house and use
your PC ?

Are relatives ?

Are you infected with viruses or non-viral malware ?

Lets find out if you are infected...

1) Download the following four items...

McAfee Stinger
http://vil.nai.com/vil/stinger/

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend Pattern File.
http://www.trendmicro.com/download/pattern.asp

Adaware SE (free personal version v1.05)
http://www.lavasoftusa.com/

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download SYSCLEAN.COM and place it in that directory.
Download the Trend Pattern File by obtaining the ZIP file.
For example; lpt422.zip

Extract the contents of the ZIP file and place the contents in the same directory as
SYSCLEAN.COM .

2) Update Adaware with the latest definitions.
3) Disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
4) Reboot your PC into Safe Mode [F8 key during boot]
and shutdown as many applications as possible.
5) Using Trend Sysclean, Stinger and Adaware, perform a Full Scan of your
platform and clean/delete any infectors/parasites found.
(a few cycles may be needed)
6) Restart your PC and perform a "final" Full Scan of your platform using the three
utilities; Trend Sysclean, Stinger and Adaware
7) Re-enable System Restore and re-apply any System Restore preferences,
(e.g. HD space to use suggested 400 ~ 600MB),
8) Reboot your PC.
9) Create a new Restore point

That message does not necessarily mean that users are logged
on to your computer via your DSL.

You get the same message on ANY networked computer if you
have network shares open to other computers on the network.

Are you on a home/business LAN?

It's not a XP specific problem, it's a common security problem that is
easier to exploit in Windows than other OS's.

Your problem is that you connect directly to the Internet without
securing your computer from attackers. In many instances, with a 1
computer network, since File/Printer sharing is enabled by default, it's
easy to connect to another persons computer.

You have two problems right now:

1) It appears that other people are using your machine/data without your
permission and you don't really know what they are doing.

2) You have an unsecured machine connected directly to the Internet.

How to resolve:

1) Purchase a CABLE/DSL Router that provides NAT, a cheap Linksys BEFSR41
unit will protect your computer from unwanted intruders and the setup for
DSL is fairly easy and painless.

2) Once you've secured your computer behind the router you need to run a
quality Antivirus scanner and a spyware scanner on it. If it were my
machine I would just wipe it and reinstall Windows again - this way I
could be sure that nothing they put on the machine would remain on it.

3) Read up on Securing Windows XP on the Microsoft site, and also about
securing IE and Outlook Express (if you use OE).

Leythos:

Since he is a Verizon customer, there is a strong possibility (depending on when Mellow
started his DSL subscription) has a Westell 2200 or 327w modem+router in which case the unit
can switched from bridge mode to Router mode.

Yes, that's good info, but, how does he get that done and will he be able
to manage it himself - for port forwarding and such or does he have to
call Verizon to have it configured. A simple, but not free, solution is to
just leave it alone and purchase a router that provides NAT so that the
user can control all aspects of the security.

One of the reasons I left this information out of my original post until he actually
replied.

I have an older Westell DSL modem (I have had Verizon DSL ~5 yrs) so I have a Linksys
BEFSR81. However, through discussions in the private Verizon News Groups [
news://news.verizon.net/0.verizon.adsl needs Verizon IP and authentication ] it uses the URL
http://192.168.1.1/ and you can switch the unit from bridge mode to router mode by self
made changes. There are also PDF manuals on the unit at
http://www.westell.com/pages/suppor...5@@@@&BV_EngineID=fadcjiiekdgdbedcfkcfkcfin.0
albeit mellow's "kit" may have printed manuals.

Do you have a wireless LAN? If so, learn how to secure it.
