Get infected by those AUTO-Play viruses?

One day, there were several computers in my office were infected by those auto-play viruses. eq. KillVBS.vbs, Reva.vbs, etc.

So, what should we do?

• First of all, press CTRL + ALT + DEL, bring up TASK MANAGER.
• Look for explorer.exe, then right click and END PROCESS TREE
• RUN again Explorer.exe, it will bring back your desktop
• Right click on C: drive, click Tools | Folder options | tab to VIEW | uncheck "Hide protected operating system files"
• It will shows all protected files, look for any suspicious *.vbs files and autorun.inf, remove those.
• Then, let's go to another steps, go to RUN | type MSCONFIG, tab to STARTUP
• uncheck any start up processes that execute suspicious *.vbs files.
• Finally to ensure that no startup process for those *.vbs, go to START | RUN | type REGEDIT.
• Explore to HKLM\Software\Microsoft\WINDOWS NT\CurrentVersion\WinLogon, look for Userinit
• The default value for userinit should be C:\WINDOWS\system32\userinit.exe,
• At the end, you could restart your computer now.

That's all for this..........
