I use Auslogics Defrag and have done for many years. With the last two updates, I have been clobbered by an IED called BoostSpeed. This program installs if you are not careful in reading the Wizard. I have twice hit the trip-wire.
To get rid of this pest, I use Revo-Uninstaller which scoops up over 50 left-over items in my registry. Why Auslogics trick innocent users into installing this registry saturating rubbish, I will never understand.
Honestly, can anybody support having BoostSpeed ? I see it as a potential trouble provoking nuisance, likely to interfere with the smooth operation of my computer.
