Reboot into safe mode (Reboot and keep tapping F8 then
choose safe mode from the list)
in Safe Mode, double-click on nailfix.bat. Your desktop
and icons will disappear and reappear, and a window
should open and close very quickly.
This will stop and delete nail.exe and svcproc.exe
Then run MS Antispy on a full system scan to remove any
other files.Ewido Security Suite and Adaware SE both
target Aurora so maybe worth trying them if you have more
problems with it.The problem is the random named file in
the system folder which will act as a re-installer each
time you reboot.Plus it changes its name whenever you
reboot.Ewido will remove those entries.Adaware will
remove Bolger and Drpmon.dll so again it could help.
