Help - Multiple iexplore processes using 100% cpu but iexplore not running

help......

i noticed the other day that i had started to get popup windows, seeing that some of the windows had CID: i tried to remove it, by doing full scans of
spybot
adaware
superantispyware
malwarebytes
avg antivirus
removing/deleting all dodgy processes/files found

but the popups didnt go away, i then checked in task manager and noticed several iexplore processes and that the pc was running at 100% cpu usage,
so i tried rebooting into safe mode and redoing the scans
again clearing out any dodgy processes reported on.
when i booted up normal, the iexplore processes were there, one process started to eat up the available memory.

I did manage to kill all of them of and the pc ran as normal until it was rebooted

having read the sticky thread regarding first steps to take to clear and the problem is still there...

hence why i am raising this thread
and log files attached as requested

nb: the other odd thing is that my avg antirus doesnt seem to be updating automatically........! i have to do it manually
