=======================

So i thought of manually removing the infected Registry keys. (Something i've done many times before)

While I was at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\
I saw a key named 'Special Accounts', it looked fishy to my paranoid eyes. Had some 'strange' values in it, None

corresponding to my Username (Administrator) or Guest. 3 were somewhat random letters with a ~, and one was '

search assistant'. Looked like malware remains of some kind, so, i deleted them all.

After that i rebooted, the welcome screen showed up (usually straightaway shows me desktop since there is just one

user 'Administrator') with the only user 'Administrator'. When i click it, it shows 'loading your personal

settings' for a second. Then it reads 'saving your settings' and stays at the logon screen. Repeated it for 10

times. Restarted and repeated. Shut Down and repeated. Always same result.

Then i tried the 'Last Know good configuration' in statup options. Still same result.
Tried 'Safe Mode' starts loading then breaks at 'unable to load NTFS.dll'
'Safe mode with networking' same logon screen and same one second login and return to logon screen.

I dont know how to login. Can someone please help. Is there a way to remotely add the keys back to my registry. Or

some way to correct this problem?

Thanks and Regards
