Please go
here & install ALL critical updates required for your system, including service pack 1a for both XP and IE6.
Most malware is designed to attack unpatched XP systems - exploiting the available 'holes' - and can bypass third-party protection on an unpatched system. The most that can be done with an unpatched system is put a temporary bandage on it. your system can potentially be reinfected within minutes of cleaning it.
