I am running a 4 month old Toshiba Satellite A135-s4467 and Vista Home Premium - every now and then I get an icon that shows up in my task bar every so often. It has no pattern of when it show up and all I have found about this program swupdate.exe that is run when I double click on the icon is that it gives me an error msg and does no updating. I only have Zone Alarm anti virus software. It speaks on the internet of an anti-virus update file that is harmless. The problem is that it wants to update and when I run it the error message appears and nothing happens so how do I get this to stop trying to run automatically?
