Please reconsider on using ASC, It creates more problems than it solves. You can add HTTPS Everywhere, VTchromiser, WOT to your E&P. You can also add Sandboxie. Nice config. Thanks for sharing with us.
Your configuration shares 2 apps in common with our own Windows 8.1, Avast & (an uninstalled iObit Advanced System Care). Instead, I have been using CCleaner which according to popular opinion on MT (I trust exterminator20) as well as from my own experience, is safe enough to use daily or even more if you'd like! A "more powerful computer" doesn't have to mean indestructible. My hope is that you'll practice careful consideration of what you click upon as well as the sites you visit online. If you download programs, as often as you can, do practice downloading directly from the developers' sites, and beware of bundled adware & PUPs.
Currently, a trustworthy site providing both information and unaltered dowloads is softpedia.com
Thanks for sharing your configuration. We hope you'll enjoy the many suggestions fellow members will share with you now & in times to come as well as contributing your knowledge too.
Fine configuration, Avast Internet Security is more bit design to tweak configuration especially using like Safe Zone and their firewall settings but still protection capabilities is not a problem; using so called Hardening Mode feature is optional and may cause a bit problem in other software that marks to be unknown source but legitimate itself.
As mentioned by other users, one cleaner software is fine and you don't need other tools to clean all junk files on your system since they have so minimal difference of their accuracy.
