Hey Quads, Trojan. Gen.2 and Zeroaccess here; XP 64 bit - advice?

Appear to be having same problems popping up that others are seeing. NAV popping up windows re: Trojan. Zeroaccess.B and Trojan.Gen.2. But, not fixing problem. I was going to download the Farbar Recovery scan tool to get you a log, but, running XP (on HP HDX laptop), I don't know if what a "PE boot CD" is. Any help, direction or advice is creatly appreciated! Thanks.

 

PS - I have a flash drive available

 

Also, the details in the scan history show the infected file at:

c:\users\me\appdata\local\{ff24043d-55f8-5ce9-a20a-8337d9b4b88}\u\

80000000.@

 

I don't know if that location helps as I cannot locate that file on the system.
