really bad virus....i need advice

[scarletboa]

ok, well i couldn't find these files:

For XP:
C:\ document and settings \ [user] \ local settings \ Application Data \ [RANDOM CHARACTERS] \
C:\ document and settings \ [user] \ local settings \ Application Data \ [RANDOM CHARACTERS]sysguard.exe
C:\ document and settings \ [user] \ local settings \ Application Data \ sysguard.exe

or

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run -> “[RANDOM CHARACTERS]”
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run -> “[RANDOM CHARACTERS]”

but everything seems normal at the moment. i am able to use my itunes and ccleaner, but the internet is not working due to firewall settings? i am doing a virus scan right now
