It also makes a fake "speedup", which installs more unwanted software (PUPs) and collects the user's information. Much like the now-viral and iconic adware BonziBUDDY, PC Optimizer Pro has received large amounts of attention after several high-profile internet live streamers examined and messed around with it, most famously Joel from Vinesauce. at times it is also misinterpreted as System Optimizer Pro.
