i use and adware 6.0 and spybot S&D 1.3 combo with norton anit virus and i always always used firefox (
www.mozilla.com) firefox will do just about everything IE does and has a builtin popup blocker. i did just run into a problem yesterday with haveing about 5 DSO exploits that spybot would find. and it would delete them but they would keep comming back. if that happens i ended up hunting down their registry entries. turns out spybot and adaware sometimes only clear they keys and don't delete them. if you delete the keys of the reoccuring DSO exploits they never come back. after i did that i've been clean since then. good luck.
