In the past week, I have received 4 notices that I was not using the most recent version of CCleaner and it downloaded a new version each time. Using Windows Professional 7, my current CCleaner is v4.19.4867 (64-bit), and I purchased it, not the free version.
WHY are there so many frequent updates in such a short period of time? Has malware hijacked my computer to come up with this, perhaps inserting garbage rather than an update? These updates appear to be originating from Piriform. If this is indeed legitimate, why not wait until all improvements are done instead of releasing multiple upgrades with what have to be minor changes so frequently?
