VBS/Shush-A is a VBS worm for the Windows platform.
VBS/Shush-A attempts to copy itself to connected drives with the name main.vbs, as well as dropping a file autorun.inf (also detected as VBS/Shush-A) to run itself automatically. If the file <System>\autorun.exe exists, it will copy it as well.
VBS/Shush-A copies itself to <System>\main.vbe and <System>\main.txt, dropping the file autorun.inf to the current and Windows system folders too.
VBS/Shush-A sets the following registry entry to run itself on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
explorer
main.vbe
