yea def turn off system restore before doing any repair, remove any crap you can from the add/remove programs that you dont want, then start in safe mode with networking support so you can update definitions for removers, i use spybot, ad-aware, giant antispyware, and websweeper, if you remove everything and restart and still get more persistant stuff google searches for removers for that kind of spy ware, if you are gonna get rid of norton make sure you get their removal tool off of their website. after you are disinfected then turn back on system restore, also some helpful ideas for future use, in ad-ware options use the custom scan and go to safety options, turn on to read only host files, also giant spyware and websweeper by webroot have active monitoring kind of like antivirus but for spyware, alerts you of activity, keep in mind that when you install stuff it may still alert you of legit stuff like if you change your homepage, plus i use a different browser, ive been using mozilla firefox and have been spyware free, spybot has a free monitor thats called tea timer that comes as an option when you install spybot. good luck
