Trojan.byteVerify

I followed Quad's instructions for the removal Trojan.byteVerify, to no avail.  Malwarebytes didn't locate anything.  Yet when I reboot,  prior to connecting to the internet, Symantec prompts me it has quaratined Trojan.byteverify.

 

I have Windows XP.  I am a novice, so have tried to follow all directions exactly as stated.

I have performed full scans using housecall, symantec, adaware and microsoft security.

 

On 3-5 Symantec left alone bloodhound.exploit.288, and did a partial removal of Trojan.byteverify from pdf(1).pdf.  and quarantined Trojan.Zefrch!gen.

 

On 3-7 Symantec left an unidentified object alone in a compressed file in in the Java Cache. 

 

on 3-9 malwarebyes located a trojan.dropper and trojan.vundo.

 

I have emptied my Java Cache, removed Java entirely.

 

What next?
