I’ve just discovered that you have branched out from anti-virus and malware fighting to cleaning up the harddisk and defragmentation. I am not very happy about this, not least because I already use ccleaner for general maintenance of the registry and removing unwanted files on the hard disk, and I never purchased avast! for that.
Also, my system disk is an SSD disk, and from Diskeeper I understand that defragmenting it may do more harm than good, and it doesn’t really speed up things anyway.
In general it is much better to specialise in what you are good at rather than starting creating a mastodont doing anything half well. So I am not at all sure that you are on the right track here. At least I am not happy with the development of avast! just now.
