AVGUI.EXE using 99 percent of processor constantly

AVG Free uses 99 per cent processor constantly. Computer is almost locked up all the time, processor very hot and the fan on constantly. Only happens if AVG Free installed.
Can Support send me the link which a Free user can use (I cannot use your Systeminfo version which asks for a subscription number ID, obviously. Then I can get the information to your support team to analyse this problem,. which is what you have asked for with other users having the same problem.
Many people have this issue and it is not resolved by uninstall and reinstall of the AVG Free program.
Many thanks.
