While no longer supported or under development by its author, OptOut served as one of the earliest freeware Spyware detection and removal tools, and as such made for a must-have download for anyone interested in protecting and ensuring their privacy. The fact that OptOut only removed Aureate/Radiate DLL files opened the door for follow-up anti-spyware tools such as Ad-aware once development of OptOut ceased.
The rest of this review dates from the program's introduction in 2000.
