Hello
KaranKohli.
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.
