Thanks David and Bob for trying to help, but I have absolutely nothing new running except Windows, ( and I have all Windows updates disabled) no Browsers no Emails no programmes. Once again, this new AvastUI.exe has only happened since the new release. If I reset Avast to factory settings, it disappears for several minutes and then pops back up again.
In the meantime I have had 3 crash to desktops with FSX (Flight Simulator) with out of memory errors, which has never happened before. I might add C:\FSX is listed in my Avast exclusions.
Is it possible to uninstall this new version and reinstall the previous version of Avast.?, or alternatively how to kill the process.
With kindest regards.
