Is my system clean now? Please help!

Hello, while running Avast! antivirus check I got these warnings:
Sign of: "JS:ClassLoader-7" has been found
Sign of "JS:Exploit-Bytverify-11" Has been found
Sign of: "VBS:Malware[Gen]" Has been found
Sign of: "Win32:Trojano-477[Trj]" Has been found
All followed by the path where they were found. I followed the instructions on how to clean that are posted here and ran the HouseCall online scan, it came back saying that "Java Bytever-a" was found in 4 files. I followed the instructions on how to remove that and did another scan, nothing was found . I do notice now that the CPU is always at 100% usage, it wasn't like that before, also there is a process I don't remember seeing before: "UStorSrv.exe" I have no idea what that is? Here is the HijackThis log.
Thanks so much in advance.
