Whenever I open a folder, another folder with the same name is
created under it.
Sol: The
system is infected by a variant of Indonesian virus called
Brontok/Rontokbro. It creates a sub-folder in a folder with same
name. Most of the times it comes from mobile memory cards. Scan with
a good anti-virus and remove the virus. Also download HijackThis and
scan your system with it in Safe Mode, then fix following entries:
C:\WINDOWS\system32\SSVICHOSST.exe
F2 -
REG:system.ini: Shell=Explorer.exe SSVICHOSST.exe

HKCU\..\Run: [Yahoo Messengger] C:\WINDOWS\system32\SSVICHOSST.exe
