help with virus/trojan picked up from LimeWire. possibly Buddy Trojan?

Sorry if a thread like this has already been posted ;\

On LimeWire I stupidly downloaded an application not thinking about what I was doing. Opened that and it came up with an error message about it not being able to be opened. Didn't pay much attention and exited out of LimeWire compleatly. a minute or so later, LimeWire re-opened and I closed it again, kept doing this though but I thought my computer was just playing up.
Went to iTunes and discovered that 780-somthing songs had had names copied then had the files deleted and turned into zip. files with a virus or something inside.

Deleted LimeWire, thought that would stop it from popping up. Now have error message every time I start the computer that there is a problem with LimeWire and something about needing to install it again. I close the message and it just pops back up again.

This all happened a couple of weeks back.

Today I installed the free version of Security Task Manager,
these are all the programmes that were of risk or that I have no idea what they are;

command.exe
svchost.exe
iexplorer.exe
kttakiyt.dll
vtstu.dll
dllhost.exe
esignypd.dll
mrofinu.exe
bwprnmon.exe
Isass.exe
aqVero182328
SiS Compatible Super VGA Tray Application
netmon
PML Driver
17PHolmes.exe
MediaBar.dll
{7E853D72-626A-48EC-A868-BA8D5E23E045}
Yahoo! Toolbar [how do I delete this?]
xtraMSN Search Toolbar
NT Fax Driver Agent For Bitware
zza.dll
avgw.exe
LimeWire [this says it starts from svchost.exe, should it be doing that?]
xtraMSN Search Toolbar [Listed twice?]

Also, it has blocked me access from anti-virus websites. I have found a list of the ones I am unable to access but have no idea how to change the settings for them ;\

And I now get annoying pop-ups from IE even though I only use FireFox.

Sorry this has been so long,
Help would be greatly apprecciated though.
thanks ;]

 

sorry, this probably seems like a really dumb question but once all of that is done, how do i get the log?

;]

 

okay, so i've found a couple of the folders it's stored itself in as zipped folders, how do i delete them compleatly off my computer?

thanks for the help ;]
will post logs once i've done this ;]
