Does your computer connect directly to the cable modem? Do you have any
software firewall or NAT router protecting you?

Could be LSP/Winsock corruption.
http://support.microsoft.com/?id=318584
http://support.microsoft.com/?id=811259

If XP SP2, Start - Run - "cmd". Type "netsh winsock reset catalog" into the
command window.

Give LSP-Fix http://www.cexx.org/lspfix.htm, WinsockFix
http://www.tacktech.com/display.cfm?ttid=257, or WinsockXPFix
http://www.spychecker.com/program/winsockxpfix.html a shot.

If no help yet, reset TCP/IP.
http://support.microsoft.com/?id=299357

Start - Run - "cmd". Type "netsh int ip reset c:\netsh.txt" into the command
window.

How current is your virus protection? Try one or more of these free online
virus scans, which should complement your current protection:
http://www.bitdefender.com/scan/license.php
http://www.pandasoftware.com/activescan
http://www.ravantivirus.com/scan/
http://security.symantec.com/ssc/home.asp
http://housecall.trendmicro.com/housecall/start_corp.asp

Now check for, and learn to defend against, additional problems - adware,
crapware, spyware.

Start by downloading each of the following additional free tools:
AdAware http://www.lavasoftusa.com/
CWShredder http://www.majorgeeks.com/download4086.html
HijackThis http://www.majorgeeks.com/download.php?det=3155
LSP-Fix http://www.cexx.org/lspfix.htm
WinsockXPFix http://www.spychecker.com/program/winsockxpfix.html
Spybot S&D http://www.safer-networking.org/index.php?page=download
Stinger http://us.mcafee.com/virusInfo/default.asp?id=stinger
TrendMicro Engine http://www.trendmicro.com/download/dcs.asp
TrendMicro Signatures http://www.trendmicro.com/download/pattern.asp
TrendMicro Instructions http://www.trendmicro.com/ftp/products/tsc/readme.txt

Create a separate folder for HijackThis, such as C:\HijackThis - copy the
downloaded file there. Create a separate folder for the two TrendMicro files,
such as C:\TrendMicro - copy the downloaded files there (unzipped if necessary).
AdAware, CWShredder, and Spybot S&D have install routines - run them. The other
downloaded programs can be copied into, and run from, any convenient folder.

First, run Stinger. Have it remove any problems found.

Next, close all Internet Explorer and Outlook windows, and run CWShredder. Have
it fix all problems found.

Next, disable System Restore.
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
Boot your computer into Safe Mode.
http://support.microsoft.com/?id=315222
Run C:\TrendMicro\Sysclean.com. Delete any infectors found. Reboot your
computer, and re enable System Restore.

Next, run AdAware. First update it, configure for full scan
(http://forums.spywareinfo.com/index.php?showtopic=11150), then scan. When
scanning finishes, remove all Critical Objects found.

Next, run Spybot S&D. First update it, then run a scan. Trust Spybot, and
delete everything ("Fix Problems") that is displayed in Red.

Then, run HijackThis ("Scan"). Do NOT make any changes immediately. Save the
HJT Log.

Finally, have your HJT log interpreted by experts at one or more of the
following security forums (and please post a link to your forum posts, here):
Aumha: http://forum.aumha.org/index.php
Net-Integration: http://forums.net-integration.net/

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 and / or WinsockXPFIx.

Finally, improve your chances for the future.

If you don't have a NAT router, or software firewall, get one or both. Please.
ASAP.

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/

Block Internet Explorer ActiveX scripting from hostile websites (Restricted
Zone).
https://netfiles.uiuc.edu/ehowes/www/main.htm (IE-SpyAd)

Block known dangerous scripts from installing.
http://www.javacoolsoftware.com/spywareblaster.html

Block known spyware from installing.
http://www.javacoolsoftware.com/spywareguard.html

Make sure that the spyware detection / protection products that you use are
reliable:
http://www.spywarewarrior.com/rogue_anti-spyware.htm

Harden your operating system. Check at least monthly for security updates.
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)).

Maintain your Hosts file (merge / eliminate duplicate entries) with:
eDexter http://www.accs-net.com/hosts/get_hosts.html
Hostess http://accs-net.com/hostess/

Secure your operating system, and applications. Don't use, or leave activated,
any accounts with names or passwords with trivial (guessable) values. Don't use
an account with administrative authority, except when you're intentionally doing
administrative tasks.

Use common sense. Yours. Don't install software based upon advice from unknown
sources. Don't install free software, without researching it carefully. Don't
open email unless you know who it's from, and how and why it was sent.

Educate yourself. Know what the risks are. Stay informed. Read Usenet, and
various web pages that discuss security problems. Check the logs from the
security products that you use regularly, look for things that don't belong, and
take action when necessary.
