I have tried to uninstall Avast4 home edition using add/remove programs in the control panel. All that happens is that it tries to reinstall Avast4.
Is their another way to uninstall Avast4 ?
Try to update your avast! program the to latest version. Then try it again.
Or you can write to support@asw.cz (or directly to my e-mail address svihalek@asw.cz) for ashClear4.exe utility to remove avast! from your system
