The way of installing MacPerformance is often deceptive. Now, you want to remove MacPerformance and it is a good idea because any adware program is a potential threat to your security and privacy. MacPerformance is not malicious, and your antivirus didn’t warn you about this potential threat. This happens if MacPerformance adware infected your computer when you installed it yourself or got it installed with a free program that you download. MacPerformance is a rogue application responsible for ads, deals, coupons, and pop-ups displayed in your Safari, Firefox, and Chrome.
