So, I know my cable service if fine. I did ipconfig and I have a ip address. I look at my network properties: It says I am connected at 10Mbits/sec. I am sending thousands of packets but receiving only 50 or 60. Apparently I am not receiving anything. I uninstalled and reinstalled my ethernet card. It still does the same thing. I cannot surf the internet nor connect to messenger services. Could it be a virus of some sort.Should I format my conputer. Please help?

Sheb,

Please provide ipconfig information for the laptop and desktop.
Start - Run - "ipconfig /all >c:\ipconfig.txt" - Open c:\ipconfig.txt in
Notepad, copy and paste into your next post.

Get Process Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml>. Provides way more
information than Task Manager. And Port Explorer (free) from
<http://www.diamondcs.com.au/portexplorer/index.php?page=home> will show you
what network connections your computer is actually opening, and what processes
are opening them.

>From each computer:
1) Ping www.yahoo.com.
2) Ping 66.94.230.33.
Report error messages.

How current is your virus protection? Try these free online virus scans:
<http://www.bitdefender.com/scan/license.php>
<http://security.symantec.com/ssc/home.asp>
<http://housecall.trendmicro.com/housecall/start_corp.asp>

Now check for, and learn to defend against, additional carriers of infection.

First, download LSP-Fix from <http://www.cexx.org/lspfix.htm>, and CWShredder
from <http://www.majorgeeks.com/download4086.html>. Both free.

Next, run CWShredder. Have it fix all variants.

Now check for, and remove, spyware. Get HijackThis
<http://www.majorgeeks.com/download.php?det=3155> and Spybot S&D
<http://security.kolla.de/index.php?lang=en&page=download>. Both free.
1) Install and run Spybot. First update it ("Search for updates"), then run a
scan ("Check for problems"). Trust Spybot, and make all recommended deletions.
2) Install and run HijackThis. Do NOT make any changes immediately. Save the
HJT Log.
3) Have your HJT log interpreted by experts at one or more of the following
forums (and post it here):
<http://forums.net-integration.net/>
<http://www.spywareinfo.com/forums/>
<http://forums.tomcoyote.org/>
<http://www.wilderssecurity.com/>

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix.

Harden your browser. There are various websites which will check for
vulnerabilities, here are three which I use.
http://www.jasons-toolbox.com/BrowserSecurity/
http://bcheck.scanit.be/bcheck/
https://testzone.secunia.com/browser_checker/

Harden your operating system. Check at least monthly.
http://windowsupdate.microsoft.com/

Block possibly dangerous websites with a Hosts file. Three Hosts file sources I
use:
http://www.accs-net.com/hosts/get_hosts.html
http://www.mvps.org/winhelp2002/hosts.htm
(The third is included, and updated, with Spybot (see above)).

Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.
