Chances are you have much more work to do!
NB: If you had no anti-virus application installed or the subscription had expired *when the machine first got infected* and/or your subscription has since expired and/or the machine's not been kept fully-patched at Windows Update, don't waste your time with any of the below: Format & reinstall Windows. A Repair Install will NOT help!
1. See if you can download/run the MSRT manually: http://www.microsoft.com/security/malwareremove/default.mspx
NB: Run the FULL scan, not the QUICK scan! You may need to download the MSRT on a non-infected machine, then transfer MRT.EXE to the infected machine and rename it to SCAN.EXE before running it.
2. [WinXP ONLY!! =>] Run the Windows Live Safety Center's 'Protection' scan (only!) in Safe Mode with Networking, if need be: http://onecare.live.com/site/en-us/center/howsafe.htm
3. Run a /thorough/ check for hijackware, including posting the requested logs in an appropriate forum, not here.

**Chances are you will need to seek expert assistance in http://spywarehammer.com/simplemachinesforum/index.php?board=10.0, http://www.spywarewarrior.com/viewforum.php?f=5, http://www.dslreports.com/forum/cleanup, http://www.bluetack.co.uk/forums/index.php, http://aumha.net/viewforum.php?f=30 or other appropriate forums as well.**
If these procedures look too complex - and there is no shame in admitting this isn't your cup of tea - take the machine to a local, reputable and independent (i.e., not BigBoxStoreUSA) computer repair shop.

This may be the wrong forum to post this question, so apologies in advance.
After clearing out some viral problems on a PC (XP home) I'm left with an
odd and annoying issue. While basic Internet conectivity is working (I can
Ping to a website using DNS, and also Telnet to port 80 and get a response),
no application seems to be able to connect to servers - things like AV
programs getting updates - and IE or Firefox can't load web pages.
All the normal settings, such as proxy and general networking parameters are
fine. Note that it's not just IE that can't connect, it seems to be ALL
apps that try to reach the Internet.
There are either some settings got broken, or system components/files gone
the same way.
Can anyone point me in the right direction to chase this down?
Thanks
Steve
