Im sorry I've had no Experience reading Hijack this Logs Maybe when Hellnoire comes on he can check it for you as ive not had a bit of experience in reading it. Sorry.
sometimes explorer.exe hangs, so I am unable to use the start menu or the quick launch.
care to elaborate a bit more.....any other problems other than the occassional hangs ??
btw, went through your log and it does appear clean. Still if you have doubts, download Hijackthis again, save it in a different location under a different name and then run it. See whether this new log and the old log are different in any way. If it is, then there might be a problem......
