Bests & Worsts Reviews from Amazon

I really like Avast Mobile Security app for my Kindle Fire. It performs well and has multi functions beyond scanning for viruses. COMPLAINT: It prompts me to install Avast Cleanup & Boost but when it takes me to Amazon app store it says "currently unavailable". Cleanup will work in conjunction with Mobile Security. When will this be back in the store? THE GOOD: Mobile Security scans apps and files, checks internet security and speed, clears clipboard, can block unwanted calks on phones, check privacy issues for app, lock sensitive apps, and a lot more. NOTE: I removed Malwarebytes it didn't seem to do much and slowed my Kindle with auto scans. Please make Avast Cleanup available again!
