Hey, I downloaded Disk Cleaner to take care of the couple of problems on my PC, but it only scanned it and now asks me to buy the full version to remove the problems it found. I was considering this option for a couple of days and during that time the notifications encouraging to buy the full version kept coming! It is actually really annoying so I started doubting if i should really obtain the program at all… What should I do? Can I trust this tool?
