Hello guys,I ask your help because I have a trouble with a possible virus in my Autocad ver. 2006. When I open autocad  it shows a pop-up  with this legend "este es un código bueno" but in the past I had never have this advise. Some commands as "explode" don't function anymore. Yesterday I did copy of some files for another collegue and when he tryed to open a file, the antivirus of his laptop detected this virus "ALS/Bursted.G Virus"in the file "acad.lsp".My PC has the Kaspersky antivirus and it has never detected this virus.Somebody can tell me how can I eliminate this virus?.Thanks a lot in advance for your support.Higbal.

I think you need to find and delete all files named "acad.lsp" and "acadapp.lsp".
 You must have received an acad.lsp file from someone along with a drawing file.
This virus is not too dangerous apparently.

higbal, did you even go back to your original post to see if THAT would fix the problem? Why create a new thread about the same thing?See this thread: http://www.cadforum.cz/forum_en/forum_posts.asp?TID=4915&KW=c%F3digo+bueno

Thanks a lot for your answering,
we found yesterday some information in order to eliminate this virus using a tool named OTMoveIT. Before to use it, the recommendation was to carry on a complete scan with ActriveScan 2.0 by Panda security in order to identify all location were the virus was allocated. Then using the mentionef tool we could remove that virus. The autocad is running well by now. If somebody needs to fix this trouble I can send you the procedure to solve it.
 
Thanks for your interesting.
Higbal
