OS: Windows XP Pro SP3
Uninstalled avast 7 as I had to clone the whole disk over to a new hard drive, as it was preventing me from booting it up. But after cloning and booting the system up successfully on the new hard drive, I tried to reinstall avast 2014 but failed without any error code. Tried to boot into safe mode to run avastclear.exe but stopped at loading aswrvrt.sys.
Attached FRST.txt from normal mode.
Edit: problem fixed.
