What to do now?

[drongo]

Could you describe in plant english, what is the problem?
Please download avz in my signature, disable your antivirus and disconnect from internet:
execute this script in avz (http://virusinfo.info/showthread.php?t=9207 ):

begin
SearchRootkit(true, true);
SetAVZGuardStatus(True);
 QuarantineFile('C:\WINDOWS\system32\ntsim.sys','');
 QuarantineFile('C:\WINDOWS\system32\drivers\ffpjin.sys','');
 QuarantineFile('e:\dental e-books\programs\oral midicine (( case & answer ))\oral midicine (( case & answer )).exe','');
BC_ImportAll
BC_Activate;
RebootWindows(true);
end.

Your system will reboot. This make just a copy of your files, no modification to your system.

Upload all quarantined files according to Appendix #3 of Rules: http://virusinfo.info/showthread.php?t=9184 , using red link above.
