How to remove or block Conficker worm infections.

Windows worm infection accelerates... conficker variants A,B,C

Conficker is a worm that spreads via networks and USB drives.  On usb drives it will create an Autorun.inf on your flashdrive. we can remove tha shit out.  go to command prompt (cmd) then type

del c:\autorun.* /f/s/q/a
del x:\autorun.* /f/s/q/a

* where "x" is your usb drive letter.

Now theres a 3megs of update for Windows XP (KB950582)  on which when u install this update it will resolve an issue in which AutoRun features were not correctly disabled.  download site: [http://www.microsoft.com/downloads/details.aspx?FamilyId=CC4FB38C-579B-40F7-89C4-1721D7B8DAA5&displaylang=en]

 

 .usb drive problem solved!  on the net side...

Conficker "opens a random port between port 1024 and 10000 and acts like a web server." to cut this blogpost short medyo sleepy na si carl. login to your home/soho router then go to Access Restriction.  block port both TCP and UDP ranging from 1024 upto 10,000.  if u have linksys wrt.. here's how. click add edit service





Conficker worm attempts to brute force usernames and passwords and takes advantage of Server Service vulnerability in Windows which allows for remote code execution. The worm also auto-updates itself every day from a long list of URLs so it looks like its preparing for a larger attack.

Remember to Turn off AutoRun feature for USB drives on your machines Patch your servers and workstations by visiting Microsoft Security Bulletin MS08-067.

Make sure your antivirus and security solution is up-to-date on the latest version and signature database.
