I downloaded your virus to my virtual machine to stimulate the experience and here is how I managed to remove it..
I have enclosed an archive file "" containing 2 batch files and 2 registry files which should help you remove the virus completely ( Follow the order 1,2,3)
Extract all files to desktop and do as follow:
1- "1- kill wscript.bat" Run this batch file to kill "wscript.exe" process
2- "2- Remove updatevb.bat" Run this batch file to completely remove "update.vbs" from startup and temp folder.
3- "3- Delete Run Key.reg" Run this batch file to delete startup key pointing to update.vbs
4- "4- Disable Wscript.reg" Run this registry file to disable wscript completely and this will protect you in the future from any vbs viruses.
