You should only have one (1) anti-virus application installed & loading at
boot! As things stand now, neither OneCare nor AVG are working properly.
Assuming (1) your OneCare subscription is and has been current, (2) you're
able to manually update OneCare, and that (3) you didn't install OneCare
after you'd installed AVG or (4) after the machine was infected with
XPAntiVirus2009 (it is now), uninstall AVG, manually update OneCare, and run
a full scan with OneCare.
If no joy...
Run a /thorough/ check for hijackware, including posting your hijackthis log
to an appropriate forum.

When all else fails, HijackThis v2.0.2
(
http://aumha.org/downloads/hijackthis.exe) is the preferred tool to use (in
conjunction with some other utilities). HijackThis will NOT fix anything on
its own, but it will help you to both identify and remove any
hijackware/spyware with assistance from an expert. **Post your log to
http://spywarehammer.com/simplemachinesforum/index.php?board=10.0,
http://forums.spybot.info/forumdisplay.php?f=22,
http://aumha.net/viewforum.php?f=30, or another appropriate forum for review
by an expert in such matters, not here.**
If the 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 or Geek Squad) computer repair shop.
