well the problem is back >:(
Now both Quick scan and full scan hangs on Windows\System32\lsm.exe

I guess ill try your recommendation of uninstalling. One curious thing is I tried running HouseCall from TrendMicro. It also hangs. I know youre not supposed to have 2 installed AV’s, but I have never had a problem running TM Housecall on any other machines while another AV was present.
