mad computer problems

[Computer is messed up really bad...]

Alright, I have no idea where these files came from, but
it all started like last weekend... I started up my
computer and after it was done booting up, it said that
it couldn't open up some files all starting with TFTP and
having various numbers at the end such as 1212, 3172,
etc. called... so I disabled it in the startup... Then I
realized that I didn't System Scan on Norton for a
while... and it found me a virus.. a W32.Spybot.Worm and
it was infected on the file explorer.exe located in
C:/Windows/System32 ... so I decided to delete it Then
my computer started messing up really bad... I noticed a
ntelnet.exe on my msconfig in startup... So I disabled
that too and then my computer wouldn't finish rebooting,
so I ctrl+alt+delete and found that ntelnet was
running... so I ended the process and it finished booting
up, now I can't even disable it because it keeps coming
back... and msconfig automatically closes on me... So
hopefully one of you guys knows how to help me.... I
decided to print screen when I opened msconfig-startup
and I found that axbwxzb.exe is running too and after
that, these tftp files keep trying to open themselves,
I've tried scandisk and everything, hopefully this
doens't come to re-formatting again... but if I must... I
guess it's the only way...

If you have Norton go to their website for detailed instructions on removing
the worm - its quite an involved process to thoroughly clean out (it may be
hiding in temp files and in some of your Restore Point backups too). Follow
the instructions in the suggested order.
Also consider setting your AV to auto start on boot up so it can do a boot
scan as well.
If you have it, you may as well use it fully.
Chek.
