The only insanity is from the people not upgrading the the 6 versions, i find the new versions run lighter than any of the old versions and if you find that isnt so then you need to look at what other software you have running that maybe causing the slow downs.
It is strange how you can call avast bloatware as they dont put any of the rubbish into there program that alot of other companys will, everything that is in the program is neccesary for the right reasons and if there are some processes you dont wish to have they can simply not be installed via a custom install or uninstalled at a later date via remove programs.
Also to come here to the avast forums and state that your using cracked keys and then you want help on an old version of avast when there is a superiour new product in every aspect for free really makes me wonder how some people even remember to breathe.
