In my opinion the future version of avast! Internet Security would be better to include parental control and more advanced surf protection or pc tuneup and backup…
If possible to improve avast antispyware protection to the Windows registry.
Parental Control: in the AIS yes, in the free antivirus, no.
PC Tuneup: not at all. Let they focus in security not in making a bloatware.
Backup: there is avast! Backup (online) yet.
Registry protection and cleaning: always welcome.
