[s]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.[/s]
Edit: problem fixed.
