Top 10 spyware threats discovered for last 24 hours

Somehow I have 180searchassistant on my system and I cant get rid of it. I have tried system restore, I have tried to use my anti-virus and anti-spyware software (Norton) to remove it and it tells me it has been removed but the files and the program keep re-creating. I cannot access my task manager it says it has been disabled by the administrator which I have not done and it has taken over my desktop properties – I cannot change my wallpaper back to what I had it keeps showing something else related to the spyware/adware program. I get false security messages pops up like every 30 seconds and about every minute or so a pop up false security message. This is driving me crazy please help me fix this!
