First time I get this virus at my computer network, this virus very strange, because I can not trace anything at startup when using HijackThis software. But when I open Recycler folder, I found a strange file name with name jwgkvsq.vmx. Also when I plug the USB flashdisk at the infected computer, it automatically create a RECYCLER folder with jwgkvsq.vmx content, also they will create autorun.inf file. Both of file and folder is hidden.
After several week, I found that Microsoft also already give a solution for the computer which is already infected by virus. By the way, the name of this virus is vary for each antivirus software. Symantec give the name Downadup for this virus, and Microsoft give name Conficker, also other antivirus give their own name. Back again to clean up this virus, Microsoft include how to find and fix this Conficker virus by download monthly Malicious Software Removal Tool. Also recommended to patch the Microsoft bug for this virus by download and running patch KB958644. All of this file can be download free at http://download.microsoft.com
Conficker is kind of unique work or virus, because this virus can infected other Windows family computers (above Windows 98), even a new service pack of Microsoft such as Windows XP service pack 3 still can be infected with this worm. But now, Microsoft is seriously try to fix this bug buy announce to Windows user to patch the computer with KB958644, and I think the Microsoft automatic update will also include this patch. At some news, they said that at 24 hours, almost 1 millions computer infected with this worm, and make the network connection become so slow. Windows 2003 server also reported down because this worm attach.
Always do a safe use for our computer. Don't forget to install the good Antivirus, we can use free for non commercial or also we can buy a better and reliable Antivirus. Don't forget to always update our Antivirus database, and always patch our computer with latest Windows Update or it is recommended to stay update with turning on automatic Windows update.
