Well you can manually remove browser history, cookies, etc. You can use windows own disk clean tools no need to use ccleaner. You can use windows defragler too.
Theres no point to instal junk/ bloat on your pc that might spy on you, or slow you instead of speeding your pc
All these speedup, driver install , cleaners etc are pretty much useless. They just do job for lazy people
What i have heard of avast bought piriform, maker of ccleaner, only god knows when they milk bloatware of from it
I personaly dont use any these kind of tools, when i can do all myself
Bitdefender trafficlight is pretty weak, it takes alot of memory too.
you can check this thread to see how these kind of extensions performance:
