it does more than that,cause i know the virus.it's also disabled your task manager and folder options.
somewhere on your system, hopefully the desk top,you will probably see a file 'new folder'.it's not a folder, it's an application! its 105 kb .i will attach the instructions from trend Micro for removal of the virus. i was unable to reset my folder options though, no matter how i tried.
also, u need process explorer, which is a fantastic third party task manager
and regtoy.i used regtoy to renable run.you need to do that cause you have to run regedit.
if you are running mcafee, it will detect that the virus has infected lssass, but it won't b able 2 do anything.you need process explorer to kill new folder exe process and lssass exe before it can be deleted.
i wish i knew how to restore my folder options, the methods i've tried won't work, Good luck!!!
you can get process explorer from sysinternals.com
google regtoy
go to this link
http://de.trendmicro-europe.com/consumer/vinfo/encyclopedia.php?LYstr=VMAINDATA&vNav=1&VName=WORM_SOHANAD.ACit will give u all d info about the virus and how u can remove it.i didn't quite follow their instruction, though.cheers
