Hi all !! Every time I log on I get the question if I would like to run the file lssas.exe, from an unknown publisher. Of course I do not want to run it, so I press Cancel button. What is this ? Is it the old Sasser or what ?? I have run the sasser removal tool from Symantec, in safe mode. It said it could not find anything. I have run Spybot, and fixed what it proposed to fix. I have run trough the whole system with Norton antivirus, without anything found. The system is XP Home SP2, Dell Dimension. Very, VERY grateful for any help. Thanks Åge
