avast 5 has an orange ball and when installed, it drives the user to uninstall version 4 and install the new one.
A lot of things changed: interface, automated actions, scheduling, etc. Besides, higher protection.
meanwhile it’s rather safe 2 upgrade 4.8 to 5.0…
i think u will like the new version, if u give it a try. ;D
@tech: on which systems did u experience that? (since the .462 version i never had probs on different oss with installing it over the old 4.8.1368, installer even overtakes the licences 2 the new version…)
