I have windows Xp loaded onto my computer and also had AVG free edition to protect it from Viruses.

Recently, my computer got infected with some trojan and virus that was very stubborn to remove by my AVG. Then, I removed AVG and installed bit defender free edition and Spybot Search and Destroy , both, to remove this nasty Virus from my computer. Bit defender did a whole system scan but was unable to remove the nasty Virus.

Spybot also detected a win32 virus along with some backdoor Trojan and showed that it was removed but a reboot and a system scan showed the same threat again. Now my computer becomes very slow after it boots up and mozilla firefox now takes twice the time it used to take while starting up.

Please suggest me a remedy to cure my computer from the virus.
