its done ... as simple as that .. unless u'r facing a multiple virus infection

there is a few time, im facing a multiple virus infection (bulubebek,sality & 2.bat) .. its a bit disaster but i managed to remove it by using safemode or administrator account.

for Vista user,
if bulubebek infected ur pc, u will not enter ur desktop(u will only see dark screen), it is because ur system cannot run 'explorer.exe' after the virus added value 'SCRIPT.exe' at the back of it on winlogon shell. so what i always do is :-

1. press CTRL-ALT-DEL and run task manager,
2. on menu bar, click FILE -> NEW TASK (RUN)
3. type explorer.exe to enter your desktop
4. after entering ur desktop, follow the step i show u earlier ...

Download RemoveBulubebek.inf
