The Happy Birthday virus is picking up great deal of popularity and is spreading a lot faster as compared to other virus. This virus mostly spreads through E-mails and flash drives like pen drives.
Following are the problems that this virus causes:
1. Disables registry editor, folder options and command prompt.
2. Shows a tool tip near the mouse cursor with the texts ‘Happy Birthday’.
3. Runs a process named either “explorce.exe” or “explorcr.exe” in the background processes that confuses with explorer.exe
4. Operating system shows “NTLDR Missing” problem.
Solution to fix the problem:
1. First of all we need to get our folder options and registry editor .
2. Now kill the process “explorcr.exe” or “explorce.exe” running in background.
3. Now go to Folder options -> tick Show Hidden Files and Folders and uncheck Hide Protected Operating System Files.
4. Delete the exe from “C:\Windows\system32” folder.
5. Also delete the “autorun.inf” file from the root drive.
6. Now to fix NTLDR missing problem, insert XP CD and Copy ‘NTLDR’ from i386\NTLDR to %SystemDrive%
7. Reboot the system.
The problem must have gone.
