How do I remove spyware from my computer

hii,i am newly joined.I read the blog by ricky on removing the malware which says "i dnt hate mozilla use firefox or else"
and followed the instructions but im not able to loctae heap41 in my computer.I am using windows xp and fedora core 7
(dual boot ) and this malware is in xp.

Actually you can't see that folder.
You have to type following in explorer address bar:

Code:

---

C:/Heap41a

---

Then only you will see the content of folder if it is there.
