Viruses unable to clean

Dear all,
I have a problem here. the following 2 viruses was found in my PC which running Windows XP home edition.

Win32:Adware-gen(Adw)
Win32:Trojano-2873(Trj)

avast on-access scanner has detected this two viruses while PC is booting up. Although I’d deleted it but it keeps coming back each time I boot up the machine.

I’d clean my machine using Trend Micro online Spyware & Virus scan, but it won’t help.

Hope you all can help me to solve this problem a.s.a.p

Thanks a lot.
