2-you misunderstood me. i'm a malewarebytes fan, what i was refering to is the fact that a lot of those tune up programs cause those malware software which need to be removed with malwarebytes
3-yes
4-agreed! i'm not saying they need to choose the anti-virus programs i
advised, but what i am saying a possible crashing if you are on older machines
don't just flat out say that i'm wrong or i don't know my stuff

especially if you misunderstood my point....
