My PC was affected by "saie.exe", tried to remove it with "Spykiller 2005", "Adaware 6.181", and "Adware SPY", but of no use. Further, Norton system works 2004 Pro was affected. . I found out that it was in the startup, and could not be removed from tools options in the IE. I restared my PC in "safe mode" and deleted the "saie.exe" program from "C:\WINNT\System32\".
I am using system "system mechanic", where i found out the name "saie.exe" and the location. It is a search assistant.
