Adding to Malke Advice, you Got this Worm: W32/Chode-W
First I recommend Uninstall Norton since Norton have been sitting Ducks for
this Worm, ehnce you said you got AVG ( did you update it's definitions yet).
= You mentioned this path:
C:\Documents and settings\...\pstord.exe Delete the executable file/folder
since it is in the My Documents and look here for Temp Files:
Then Open windows explorer and delete the Temp:
C:\Windows\Temp\TemporaryInternet Files =< Delete all sub-folders in capital
letters they will be here>
= To access the Hosts file do the following:
Open the Windows Explorer and locate this path:
C:\Windows\System32\drivers\etc = look in the Right Pane/window for this
file called the HOSTS file but not the one with the extension *.SAM* leave
this as is.
If you can't see it try to click Tools >> Folder Options and select show
Hidden files and folder, then right Click the Hosts file and select open with
Notepad. //*** Remember to Hide your system files after you find your
file***//
There see any reference for that site and remove it, you Hosts file will
looks like this:
# 102.54.94.97 rhino.acme.com # Source server
# 38.25.63.10 x.acme.com # Client Host
127.0.0.1 LocalHost
------------------------------------------
Remove all other References other than those above.

forums for analysis and troubleshooting:
