Java Exploit trojan found, comes back after removal-please help!

It started about 3 wks ago, desktop started acting up. Noticed svchost was constantly using 50-80% cpu. Desktop screen flickers and appears to get hijacked.. (not sure). Ran Eset scan and found Java exploit and was removed. Feeling very uneasy using this machine. Running Win XP os on Uverse wireless dsl line. Also, it works so very different while in safe mode, much quicker and svchost issue seems to stop. I could really use some assistance with removing this nasty virus/trojan. I suspect this was a result of using outdated Java 6, but not sure. Thanks in advance for your time!!
