It’s less common now, but I do remember helping multiple people in the past who had installed malware masquerading as “PC Optimiser” software. Usually these would contain big green buttons labelled something like “Optimise system RAM” and show lists of many problems it was helpfully fixing for you. Some users were utterly convinced that their machine was running faster than ever before, when in reality the malware did nothing other than begging for cash payments. Often the opposite by slowing down the machine with continuous pop-up advertisements and other nasties.
