I have used AIO, All in One Toolbox for years and it really helps me keep my phone running faster. I primarily just use the boost, ram boost, clean, CPU cooler & startup manager. I also use Malwarebytes on my PC and my Note 9.(& MotoZ Play and Samsung TabE) They keep things running smoothly for me. Malwarebytes now has virus protection too so that's why I use it. It is good on all my devices. I don't mind helping a good developer for a well respected product. My son works for a place that fixes people's PC's & he's always removing viruses and malware etc. Of course he said I should get Vyper & use the smaller Malwarebytes.
(On PC) Only the latter is needed on my android. I had Avast and it seemed OK but very intrusive.
Btw, not sure if this is the same thing but there is at least one pain in the... (ex sailor censored) thing that happens from time to time but isn't malware according to the Malwarebytes tech I spoke with. It involves an intrusive ad when you go to some sites. (AC flagged my post as spam so sorry if I am not being as informative as I had tried to be. Just trying to help) It takes over your browser page and said you won blah blah blah. They told me to delete the cache, uninstall & reinstall the browser and that worked. So even when it wasn't malware, they will still help you. I appreciate that.
I hope this one goes thru.
3rd time's a charm
I give up. Don't know what's wrong with what I wrote.
