I ran OTL again. This time, OTL has disappeared from the download folder and I cannot see it any longer under C:\ . The OTL shortcut on the desktop doesn’t work any longer (this, I know I can safely delete). I still have on the desktop 3 RK report + 1 quarantine folder + 1 Malwarebyte log.
Thank you for the answer regarding the file hippo update checker. To make sure : will it live happy with the windows updater?
Besides, I periodically run CCleaner (from a previous computer, I learnt you should do computer cleaning as you do house cleaning) ( ;). Each time, I see CCleaner can fix registry as well. On one hand, I hear that registry is touchy matter and only skilled people should deal with it. On another hand, I hear that over time, havoc builds up in the registry and it not good for the computer. Is using CCleaner “fix registry” a safe part of good maintenance or should I keep on keeping away from it? (Hopefully you won’t tell me to download and update regularly one more software!)
