180search assistant

Hi,
I think I've been infected with spy ware -- L
-- Here's my info:

1. System: XP (User accounts: Administrator and guest)

2. Browser: SBC Yahoo! Browser DSL Version 5.01-ACSX;SP2

3. Problem: “180search Assistant” (spyware?) keeps popping up and asking to be reinstalled; and a program, “WebRebates_CDT_InstallSilent,” keeps reappearing in my Temp folder after I’ve deleted it. Also, I had a few warnings from the Norton program that “c:\temp\salm.exe” was attempting to access the internet -- I went and manually deleted that file. I believe all three of these programs are connected (???).

4. Security Software running: Norton Internet Security and AntiVirus; firewall; Spybot S&D; SpywareBlaster; CWShredder. -- They are all up to date.

5. Steps taken:
-- I’ve deleted all the files associated with these programs in the Temp folder, when I tried to delete “180search assistant” from the add/remove programs page it gave me an error message saying that it had already been deleted -- but, it still shows up on the page;
-- I’ve run virus scans on Norton (and TrendMicro online) which didn’t find anything;
-- Spybot S&D scans find “DSO Exploit” (but, I’ve been told that that’s a false positive);
-- CWShredder finds two things: “CWS.Jksearch” and “CWS.HiddenDll” (I‘ve run this scan a couple of times to remove them and they keep coming back).

6. Both Grokster and Kazaa were installed at some point -- several teenagers use my computer -- I deleted those programs a couple of months ago, but they still show up in my add/remove programs page and give me error messages when I try to delete them (I think they‘re mostly gone, though).

7. I’ve included reports from both Spybot S&D and CWShredder as attachments.


Any advice would be greatly appreciated, I'm scratching my head on this one.
-- Thanks in advance for your help!
