Use SpywareBlaster instead of SpyBot.
Add-in other on-demand scanners i.e., HitmanPro. For Google Chrome HTTPS Everywhere is good.
instead of using advanced system optimizer I recommend to switch to wisecare 365 free or iobit advanced systemcare : these two are way better then the one you are using. aso is not very trustworthy....
