I will not install any of that software even if I get paid for using it!
It is redundant and invasive piece of software that does nothing that cannot be accomplished using built-in utilities.
Remember the Driver Doctor that detected "bad" drivers and asked for money to install "good" drivers. It is similar to ransomware with exception it did not encrypt the files.
Partially agree with you, but FIRSTLY - Driver Booster is probably the best in the world for average user and also very popular, and SECONDLY - other IOBit softwares are also no so bad. Keep in mind that there are very large difference between experienced computer user like you and average computer user.
