i have avast 4 home installed on vista64 home premium.
i updated the latest comodo firewall and it screwed the functionality of avast.
i tried to reinstall avast 4 home and it would not do anything.
when i try to uninstall from the control panel, it gives me an error code box (sorry, i did not write it down)
i tried to delete the avast folders and files in the safe mode but it denies me the permission (same in regular windows) even though i am the administrator and the only user of the laptop.
