上網找的答案：

180 Search Assistance is a search engine tool very similar to google but it is also a very well known spy-ware as well. If you go into your installed programs and look for it. Once found delete it. Although it sounds like you have antivirus software already that has tried to delete it and now it's trying to get back into your system. I suggest some software called Spy-Bot and Ad-aware these are both free to down load and will go through your entire system looking for nasties ...once they are found kill them off.

I sugest to everyone they down load these programs as you will be very suprised by the amount of crap that gets pulled off pop-ups even when you don't click on them!

去到他們的網站
就能移除了

http://www.180searchassistant.com/privacy.html

可能開某些網頁，就會自動安裝吧，找出那個網頁，不要再去，不然就用一些檔****的軟體檔他...............應該有用吧

這讓我想起以前常中的 3721................

Go to Start Menu
Under Settings select Control Panel
Select Add or Remove Programs
Click on Uninstall 180search Assistant
(If you are running an older version of our software, this will be named PAD Lookups by N-Case)
Select Remove and follow instructions until prompted with "You have successfully uninstalled 180search Assistant"

問題我新增/移除程式沒有他說的那個軟體，真是見到鬼了。

如果用spybot 1.3
不知掃不掃得到？
